2023-06619. Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for Rufa Red Knot

AGENCY:

Fish and Wildlife Service, Interior.

ACTION:

Proposed rule; revisions and reopening of comment period.

SUMMARY:

We, the U.S. Fish and Wildlife Service (Service), announce the reopening of the comment period on our July 15, 2021, proposed rule (hereinafter the “2021 proposed rule”) to designate critical habitat for the rufa red knot ( Calidris canutus rufa) under the Endangered Species Act of 1973, as amended (Act). In this document, we present revisions to the critical habitat designation we proposed for the species in the 2021 proposed rule. As a result of the critical habitat revisions, we now propose to designate a total of approximately 683,405 acres (276,564 hectares) as critical habitat for the rufa red knot across 127 units (18 of which are further subdivided into 46 subunits) in Massachusetts, New York, New Jersey, Delaware, Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and Texas. This amounts to an overall increase of 32,615 acres (13,199 hectares) in our proposed critical habitat designation for the species. This revision includes seven new units in Massachusetts, New York, Virginia, North Carolina, South Carolina, and Georgia; revised units in Massachusetts, New Jersey, South Carolina, Georgia, and Texas; and corrections to reported acreages/hectares for four other units and the total acreage in the 2021 proposed rule. We are reopening the comment period to allow all interested parties the opportunity to comment on the 2021 proposed rule, as well as the revisions described in this document. Comments previously submitted need not be resubmitted, as they will be fully considered in preparation of the final rule. If the determination is finalized, the final rule will include responses to the comments previously received from the 2021 proposed rule and any comments received as part of this document's reopening of comments.

SUPPLEMENTARY INFORMATION:

Public Comments

We will accept written comments, information, and additional data during this reopened comment period on our July 15, 2021, proposed rule to designate critical habitat for the rufa red knot (86 FR 37410) (hereinafter the “2021 proposed rule”), the revisions to the proposed critical habitat designation that are described in this document, and our revised draft economic assessment (DEA) of the proposed critical habitat designation. We will consider information and recommendations from all interested parties. We are interested in comments concerning:

(1) The reasons why we should or should not designate habitat as “critical habitat” under section 4 of the Act (16 U.S.C. 1531 et seq.), including information to inform the following factors that the regulations identify as reasons why designation of critical habitat may be not prudent:

(a) The species is threatened by taking or other human activity and identification of critical habitat can be expected to increase the degree of such threat to the species;

(b) The present or threatened destruction, modification, or curtailment of a species' habitat or range is not a threat to the species, or threats to the species' habitat stem solely from causes that cannot be addressed through management actions resulting from consultations under section 7(a)(2) of the Act;

(c) Areas within the jurisdiction of the United States provide no more than negligible conservation value, if any, for a species occurring primarily outside the jurisdiction of the United States; or

(d) No areas meet the definition of critical habitat.

(2) Specific information on:

(a) The amount and distribution of rufa red knot habitat;

(b) What areas, that were occupied at the time of listing (specifically referring to January 12, 2015, which is the effective date for the December 11, 2014, final listing rule (79 FR 73705)) and that contain the physical or biological features essential to the conservation of the species, should be included in the designation and why;

(c) Special management considerations or protection that may be needed in critical habitat areas we are proposing, including managing for the potential effects of climate change; and

(d) What areas not occupied at the time of listing are essential for the conservation of the species. We particularly seek comments regarding:

(i) Whether occupied areas are adequate for the conservation of the species; and

(ii) Specific information regarding whether or not unoccupied areas would, with reasonable certainty, contribute to the conservation of the species and contain at least one physical or biological feature essential to the conservation of the species.

(3) Information on land ownership and land use designations and current or planned activities in the subject areas and their possible impacts on the proposed critical habitat.

(4) Information on the projected and reasonably likely impacts of climate change on the rufa red knot's proposed critical habitat.

(5) Any probable economic, national security, or other relevant impacts of designating any area that may be included in the final designation, and the benefits of including or excluding specific areas.

(6) Information on the extent to which the description of probable economic impacts in the draft economic analysis is a reasonable estimate of the likely economic impacts.

(7) Whether any specific areas we are proposing for critical habitat designation should be considered for exclusion under section 4(b)(2) of the Act, and whether the benefits of potentially excluding any specific area outweigh the benefits of including that area under section 4(b)(2) of the Act, in particular those based on a conservation program or plan, and why. These may include Federal, Tribal, State, county, local, or private lands with permitted conservation plans covering the species in the area such as habitat conservation plans, safe harbor agreements, or conservation easements, or non-permitted conservation agreements and partnerships that would be encouraged by designation of, or exclusion from, critical habitat. Detailed information regarding these plans, agreements, easements, and partnerships is also requested, including:

(a) The location and size of lands covered by the plan, agreement, easement, or partnership;

(b) The duration of the plan, agreement, easement, or partnership;

(c) Who holds or manages the land;

(d) What management activities are conducted;

(e) What land uses are allowable; and

(f) If management activities are beneficial to the rufa red knot and its habitat.

(8) Ongoing or proposed conservation efforts that could result in direct or indirect ecological benefits to the associated habitat for the rufa red knot; as such, those efforts would lend to the recovery of the species and therefore areas covered may be considered for exclusion from the final critical habitat designation.

(9) Whether we could improve our data or modify our approach to designating critical habitat in any way to provide for greater public participation and understanding, or to better accommodate public concerns and comments or to better effectuate the purposes of the Act.

If you submitted comments or information on the 2021 proposed rule or DEA during the comment period that was open from July 15, 2021, to September 13, 2021, please do not resubmit them. Any such comments are already part of the public record of this rulemaking proceeding, and we will fully consider them in the preparation of our final determination. Once the determination is finalized, the final rule will take into consideration all written comments and any additional information we receive during both comment periods. The final decision may differ from this revised proposed rule, based on our review of all information we receive during this rulemaking proceeding.

You may submit your comments and materials by one of the methods listed in ADDRESSES . We request that you send comments only by the methods described in ADDRESSES .

If you submit a comment via https://www.regulations.gov, your entire comment—including any personal identifying information—will be posted on the website. We will post all hardcopy comments on https://www.regulations.gov as well. If you submit a hardcopy comment that includes personal identifying information, you may request at the top of your document that we withhold this information from public review. However, we cannot guarantee that we will be able to do so.

Comments and materials we receive, as well as supporting documentation we used in preparing the proposed rule and DEA, will be available for public inspection on https://www.regulations.gov at Docket No. FWS–R5–ES–2021–0032, or by appointment, during normal business hours, at the U.S. Fish and Wildlife Service, New Jersey Ecological Services Field Office (see FOR FURTHER INFORMATION CONTACT ).

Background

It is our intent to discuss in this document only those topics directly relevant to these revisions of the proposed designation of critical habitat. For more information on the species, its habitat, and previous Federal actions concerning the rufa red knot, refer to the 2021 proposed rule. Proposed critical habitat for the rufa red knot consists of the area described in the 2021 proposed rule, as modified by the revisions explained in this document; both together constitute the revised proposed designation of critical habitat.

On July 15, 2021, we published the 2021 proposed rule to designate critical habitat for the federally threatened rufa red knot in 120 units (18 of which are further subdivided into 46 subunits) encompassing approximately 649,066 ac (262,667 ha) in Massachusetts, New York, New Jersey, Delaware, Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and Texas. In addition, we announced the availability of a DEA of the proposed critical habitat designation. We accepted comments on the proposed rule and DEA for 60 days, ending September 13, 2021. We also received a congressional request for additional time to review and comment on the proposed rule. Based on information we received during the public comment period and our reanalysis of the best available information, we propose to revise the critical habitat designation and are, therefore, reopening the comment period to allow the public additional time to submit comments on both the 2021 proposed rule as well as the revisions described in this document.

New Information and Revisions to Proposed Critical Habitat

During the public comment period, we received 92 comment letters, 59 of which contained substantive comments on the proposed critical habitat designation. We became aware of some new information during this time period, including some information based on comments received ( i.e., site-specific survey or observation data from multiple sources, and flock count data across the range of the species from bandedbirds.org). This new information and comments received during the open comment period prompted us to reevaluate the best available information across the range of the species. In some areas, this resulted in the addition or revision of unit boundaries per the methodology used to designate critical habitat (see https://www.regulations.gov, Docket No. FWS– R5–ES–2021–0032, Supplementary Document FWS–R5–ES–2021–0032–0004). This information has resulted in changes to six units described in the 2021 proposed rule's critical habitat designation, and the addition of seven units based on areas that we found to meet the definition of critical habitat. No new areas are being proposed beyond the coastal States and counties already included in the 2021 proposed rule's critical habitat designation. The revised and new units are described in this document.

In this document, we propose certain revisions to the critical habitat designation we proposed for the rufa red knot in the 2021 proposed rule. Because of these revisions, the numbering for some of the critical habitat units has changed from the 2021 proposed rule, although the names and descriptions remain the same for these units/subunits (with the exception of one unit in Georgia (GA–7) with a name change). All revisions to unit numbers are described below and listed in table 1.

Specifically, there are no changes within the States of Alabama, Louisiana, and Mississippi. We corrected acreages, hectares, or both for Unit DE–4 in Delaware, VA–14 in Virginia, GA–9 in Georgia, and FL–1 in Florida that were incorrectly reported in the 2021 proposed rule; no other changes were made to these or other units in Delaware, Virginia, and Florida. We propose the following unit revisions or unit additions in the States of Massachusetts, New York, New Jersey, Virginia, North Carolina, South Carolina, Georgia, and Texas; all revisions or additions are areas occupied by the rufa red knot at the time of listing. Our regulations at 50 CFR 424.02 define the geographical area occupied by the species as an area that may generally be delineated around species' occurrences, as determined by the Secretary ( i.e., range). Such areas may include those areas used throughout all or part of the species' life cycle, even if not used on a regular basis ( e.g., migratory corridors, seasonal habitats, and habitats used periodically, but not solely, by vagrant individuals). Revisions are summarized here and full descriptions and acreage changes follow in the “Revised Proposed Critical Habitat Designation” section, below:

(1) Massachusetts: We are revising unit numbers because we are adding one unit based on our review of comments received during the previous open comment period. Specifically, this addition is based on our reanalysis and consideration of observation data (Harrington et al. 2010, entire; Faherty 2021a, pers. comm.; Faherty 2021b, pers. comm.), and consideration of flock count observations between 2010 and 2019 from bandedbirds.org (BandedBirds 2021, entire). The new Unit MA–1 (Nauset Marsh) occurs in the towns of Orleans and Eastham in Barnstable County, to include the area of Salt Bay Pond, Nauset Bay, Nauset Spit, and Coast Guard Beach. We are also revising Unit MA–2 (Pleasant Bay; formerly Unit MA–1) based on our review of the same bandedbirds.org flock count observations. This revised unit begins at the northeastern end of Little Pleasant Bay and continues south along Nauset Beach South and North Beach to North Beach Island, terminating at the natural channel between North Beach Island and South Beach Island (Chatham).

(2) New York: We are revising unit numbers because we are adding one unit based on our reanalysis of information in our files ( i.e., past surveys by Virginia Tech conducted on Fire Island for the Service between 2016 and 2018). In other words, during our reevaluation of the best available information, we determined an error when applying the methodology and this unit should have been included previously. The new Unit NY–2 (Old Inlet) occurs in Suffolk County, surrounded by the waters of Bellport Bay and the Atlantic Ocean. Also, we corrected the county name on the map for NY–1 to Suffolk County.

(3) New Jersey: We are revising the boundary of Unit NJ–1 to reflect the development and growth of a new island east of Little Beach Island. Little Beach Island is within the Edwin B. Forsythe National Wildlife Refuge (NWR). The new island, located approximately 1,250 feet (ft) (381 meters (m)) offshore of Little Beach, is State-owned land. Prior to emerging as a full island in 2020, a smaller exposed shoal was present in this area in 2017, and was known to support rufa red knots during fall migration by 2019. Based on the high quality of this habitat, the high level of use by rufa red knots, and its protection from disturbance, we made a minor adjustment to the boundary of this unit to include the entire island at its current size and configuration. Due to the highly dynamic and shifting nature of this new island, the expanded boundary also includes areas of open waters surrounding the island in which shoaling was indicated in recent years. These minor adjustments to the boundary of this unit were made by referencing recent base maps that show the current extent of the island.

(4) Virginia: We are revising some unit numbers because we are adding two units based on rufa red knot occupancy and habitat use information received by The Nature Conservancy (TNC) and also recommended by the State of Virginia (Virginia Department of Wildlife Resources 2021, p. 1; TNC 2021, p. 2; Wilke 2021, pers. comm.). The new Unit VA–12 (Ship Shoal Island) occurs in Northampton County, including both Ship Shoal Island and the area known as Godwin Island. The new unit VA–15 (Fisherman Island) occurs in Northampton County at the mouth of the Chesapeake Bay and just south of the tip of the Eastern Shore peninsula, surrounded by the waters of the Chesapeake Bay and Atlantic Ocean. As noted above, we also corrected the acreage/hectares that were incorrectly reported for Unit VA–14 (Smith Island; formerly VA–13) in the 2021 proposed rule.

(5) North Carolina: We are revising some unit numbers because we are adding one unit based on rufa red knot occupancy and habitat use information received from Audubon North Carolina (Audubon North Carolina 2021, p. 2; Addison 2021, pers. comm.). The new Unit NC–6 (Lea-Hutaff Island) occurs in Pender and New Hanover Counties, stretching from the west side of New Topsail Inlet channel west across the Rich Inlet channel to the northeast end of Figure Eight Island.

(6) South Carolina: We are revising some unit numbers because we are adding one unit based on our review of comments received from the South Carolina Department of Natural Resources (SCDNR) (SCDNR 2021, p. 3). The new Unit SC–22 (Bay Point Beach) occurs east of Hilton Head Island on the eastern side of Port Royal Sound in Beaufort County. We are also revising and renaming Unit SC–21 (Fripp Island, Pritchards Island, and Little Capers Island Beaches) and revising Unit SC–25 (Turtle Island and Tomkins Island Beaches; formerly Unit SC–24, Turtle Island Beach) based on our review of comments received from the SCDNR (SCDNR 2021, p. 3). Units SC–21 and SC–25 include both a change to the unit name and the unit boundary. The revised Unit SC–21 begins at the Fripp Inlet shoreline of Fripp Island, continues along the Atlantic coast shoreline of Fripp Island, and now extends along the Atlantic coast shoreline of Pritchards Island and Little Capers Island. The revised Unit SC–25 begins at the Calibogue Sound shoreline of Turtle Island and now includes all of Tompkins Island in Calibogue Sound east of Turtle Island, although the adjusted boundary actually resulted in an overall decrease of 27 ac (11 ha) in unit size compared to the 2021 proposed rule.

(7) Georgia: We are revising unit numbers because we are adding one unit and revising two units based on our review of comments received from the Georgia Department of Natural Resources (GADNR) (GADNR 2021, p. 2; Smith 2021, pers. comm.). The new Unit GA–1 (Cockspur Island and Daymark Island Beaches) occurs in the Savannah River adjacent to Tybee Island in Chatham County. Units GA–5 and GA–10 include both a change to the unit name and the unit boundary; we also renamed Unit GA–7 to St. Catherine's Island Beach and St. Catherine's Island Bar (formerly St. Catherine's Island Beach). The revised Unit GA–5 (Little Ogeechee River Shoreline and Raccoon Key; formerly Raccoon Key) now begins at the Green Island shoreline of the Little Ogeechee River, continues east along the shorelines of Little Wassaw Island and Pine Island to the Odingsell River entrance behind Wassaw Island. The revised Unit GA–10 (Queens Island, Wolf Island, Egg Island, Little Egg Island, and Little Egg Bar; formerly Wolf Island, Egg Island, Little Egg Island, and Little Egg Island Bar) now begins at the Black River shoreline of Queens Island and extends south along the Wolf Island shoreline, which includes Wolf Island Bar, to the eastern and southern shorelines of Little Egg Island Bar Natural Area southwest to Egg Island in the Altamaha Sound. As noted above, we also corrected the acreage/hectares that were incorrectly reported for Unit GA–9 (Sapelo Island Beach; formerly GA–8), and changed the name for Unit GA–7 to “St. Catherine's Island Beach and St. Catherine's Island Bar” (formerly GA–6, St. Catherine's Island Beach) in the 2021 proposed rule.

(8) Texas: We are revising two proposed units of critical habitat—Units TX–1 (Rollover Pass to Bolivar Flats) and TX–11 (South Bay/Boca Chica)—based on our reanalysis of the best available information, including comments received during the open comment period. In our review of the flock count observation data from bandedbirds.org provided during the open comment period, we identified an error in the proposed boundary of Unit TX–1, which occurs in Galveston County. Based on eBird data and our assessment of habitat features, as described in the 2021 proposed rule, unit description, Unit TX–1 should include additional sand flats habitat on the bayside of Rollover Pass. Additionally, due to an oversight, we are proposing including additional adjacent habitat to the proposed Unit TX–11, which occurs in Cameron County. This unit should be extended to the east of South Bay to include important habitat features that should have been included previously; although the boundary should change to incorporate adjacent habitat features, the detailed unit description will not change.

Finally, when we conducted a reanalysis of the best available information, we determined two incorrect total State acreages for rufa red knot proposed critical habitat that affected the calculation for the overall/total acreage of the proposed critical habitat designation. In short, the total acreages calculated for the States of North Carolina and Florida were incorrectly summed, resulting in the overall proposed critical habitat acreage reported as 649,066 ac (262,668 ha). With the corrected summed values for these two States, the total acreage for the 2021 proposed rule should have been 650,791 ac (263,366 ha). When considering this corrected total acreage and the revisions, additions, and corrections described herein, the revised proposed critical habitat designation total is 683,405 ac (276,564 ha), resulting in an overall increase in proposed critical habitat of 32,615 ac (13,199 ha).

All of the additional unit acreage in the above-described revised and new units were occupied at the time of listing and are currently occupied, contain one or more of the physical or biological features to support life-history functions essential to the conservation of the rufa red knot, and may require special management considerations or protection from threats as described in the 2021 proposed rule. For clarity, we also propose to add short textual descriptions of each proposed unit in the regulatory text of the critical habitat designation.

The Draft Economic Analysis (DEA) for the proposed critical habitat designation, entitled: Draft Screening Analysis of the Likely Economic Impacts of the Proposed Rule to Designate Critical habitat for the Rufa Red Knot (IEc 2021a) has been revised to include additional information for the counties containing the new units (MA–2, NY–2, VA–12, VA–15, NC–6, SC–22, and GA–1) and revised units (Units NJ–1, SC–21, SC–25, GA–5, GA–10, TX–1, and TX–11) (IEc 2021b). Based on consultation history for the rufa red knot and with consideration of the areas added in this revised proposed rule, the number of future consultations, including technical assistances, is likely to be approximately 250 per year on average. The additional administrative cost of addressing adverse modification in these consultations is likely to be less than $550,000 per year. This represents a 15 percent increase in cost relative to the April 2021 version of the DEA, which also likely overstates rather than understates the impacts (IEc 2021b, p. 17).

Physical or Biological Features Essential to the Conservation of the Species

For a full description of the physical or biological features essential to the conservation of the rufa red knot, refer to the 2021 proposed rule. No changes were made to the physical or biological features, which include:

(1) Beaches and tidal flats used for foraging;

(2) Upper beach areas used for roosting, preening, resting, or sheltering;

(3) Ephemeral and/or dynamic coastal features used for foraging or roosting;

(4) Ocean vegetation deposits or surf-cast wrack used for foraging and roosting;

(5) Intertidal peat banks used for foraging and roosting;

(6) Features landward of the beach that support foraging or roosting; and,

(7) Artificial habitat mimicking natural conditions or maintaining the physical or biological features 1 to 6 (above).

Revised Proposed Critical Habitat Designation

In total, we now propose to designate approximately 683,405 ac (276,564 ha) in 127 units (18 of which are further subdivided into 46 subunits) as critical habitat for rufa red knot in Massachusetts, New York, New Jersey, Delaware, Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and Texas. The proposed critical habitat areas described below constitute our best assessment, at this time, of areas that meet the definition of critical habitat, and all units were occupied at the time of listing and are considered currently occupied by the species. Table 1, below, shows the proposed unit or subunit names, land ownership, and approximate acreage. Where appropriate, table 1 also notes the previous number for units for which the numbering has changed.

As noted in the 2021 proposed rule, the land ownership values in many (but not all) proposed critical habitat units also include a category called “uncategorized lands.” For the purposes of this analysis and proposed critical habitat designation, this category refers to open water. Although open water is not rufa red knot habitat per se, it is an integral part of the habitat mosaic that these birds require. Rufa red knots use the edges of certain coastal ponds, marsh blowouts, salt pannes, and sand or mud flats that may be classified by some States as open water if they are submerged during high tides. Additionally, open waters at inlets are regularly reshaped by natural coastal processes that create and maintain dynamic and ephemeral rufa red knot habitat features, such as shoals and spits.

The areas we propose as critical habitat for the rufa red knot are organized by State, north to south; thus, some units were renumbered when new units were included in between other units that were presented in the 2021 proposed rule's critical habitat designation. This document presents brief descriptions of the revised and new units, including the reasons why they meet the definition of critical habitat for the rufa red knot. Also, many of the proposed units presented in the 2021 proposed rule (including some of the revised and new units presented in this document) overlap in part or whole with existing critical habitat designated for one or more other federally threatened species ( i.e., the piping plover (Charadrius melodus), the loggerhead sea turtle (Caretta caretta), the Gulf sturgeon (Acipenser oxyrinchus desotoi), and the West Indian manatee (Trichechus manatus)), and one federally endangered species ( i.e., the aboriginal prickly-apple (Harrisia aboriginum)). Table 2, below, shows the acreage of overlap between the rufa red knot proposed critical habitat designation and the existing critical habitat designated for these other federally listed species, including notation of changes based on this revised proposed rule.

Additional considerations for the previously proposed units and the revised or new units presented in this document include:

(1) Most of the units contain highly dynamic barrier beaches and intertidal seashore areas that are covered at high tide and uncovered at low tide. This area has the potential to vary year-to-year. In other words, the precise location of the physical or biological features may shift daily as a result of tides, but also may shift over time somewhat because of the intrinsically dynamic nature of shorelines and due to sea level rise. In general, the physical or biological features we describe are the intertidal areas and sandy beaches up to the vegetated or developed areas that do not contain the physical or biological features.

(2) The availability of different habitats based on the tide cycle may also cause rufa red knots to vary foraging or roosting locations throughout a day and/or forage at night.

1  The amount of rufa red knot proposed critical habitat overlapping with piping plover designated critical habitat increased by 852 ac (345 ha) in North Carolina, 660 ac (267 ha) in South Carolina, 508 ac (205 ha) in Georgia, and 371 ac (150 ha) in Texas; this resulted in a total increase of 2,413 ac (976 ha) for piping plover compared to the July 15, 2021, proposed rule. The amount of rufa red knot proposed critical habitat overlapping with loggerhead sea turtle designated critical habitat was corrected for North Carolina, to include adding acreage for the new NC–6 unit, to 3,438 ac (1,391 ha); overlap also increased by 692 ac (280 ha) in South Carolina, resulting in a total increase of 608 ac (246 ha) for loggerhead compared to the July 15, 2021, proposed rule.
2  Totals may not sum due to rounding.

The revised proposed critical habitat designation is defined by the map or maps, as modified by any accompanying regulatory text, presented at the end of this document under Proposed Regulation Promulgation. The rule portion of this document depicts all the proposed critical habitat units, including those originally proposed July 15, 2021, and unchanged via this document. Because we are adding proposed critical habitat units, the paragraph designations have changed, so we are setting forth the entire proposed rule in this document instead of just the new and revised proposed critical habitat units.

We include more detailed information on the boundaries of the revised proposed critical habitat designation in the discussion of new and revised proposed individual units below. For units for which we are not proposing any changes from the July 15, 2021, proposed rule, please refer to information at https://www.regulations.gov under Docket No. FWS–R5–ES–2021–0032.

Unit MA–1: Nauset Marsh

Unit MA–1 consists of approximately 2,219 ac (899 ha) of highly dynamic barrier beaches and intertidal ( i.e., seashore that is covered at high tide and uncovered at low tide) areas in the towns of Orleans and Eastham in Barnstable County, Massachusetts. The unit includes exposed intertidal flats, shoals, mudflats, and intertidal salt marsh pannes in Salt Pond Bay and Nauset Bay, and ephemeral tidal pools, primary sand dunes, and beaches associated with Nauset Spit (Orleans and Eastham) and Coast Guard Beach (Eastham). The southern end of the unit begins at Nauset Spit north of Mill Pond where the peninsula is bordered by bay and oceanside waters, and heads east following the mainland shoreline past Woods Cove (but not including the cove) to the shoreline of Fort Hill (Eastham). The unit then follows the shoreline around Salt Pond Bay to the north end of Nauset Bay where the boundary continues east across Coast Guard Beach to mean low low water (MLLW; i.e., the lowest of the low tides per day averaged over a 19-year period) on the ocean side. The eastern unit border continues south crossing the inlet between Coast Guard Beach and Nauset Spit (Eastham) following oceanside MLLW until the spit is no longer bordered by the bay and ocean, at which point the boundary heads west. Lands within this unit include approximately 1,340 ac (543 ha; 60 percent) in Federal ownership, 136 ac (55 ha; 6 percent) in private/other ownership, and 744 ac (301 ha; 34 percent) that are uncategorized. General land use within this unit is primarily recreational, including offshore and surf fishing, shellfish digging (both recreational and commercial), boating, over-sand vehicle use, sunbathing, swimming, and walking.

Unit MA–1 is occupied by the species and contains one or more of the physical or biological features essential to the conservation of the species. The unit contains a high concentration of rufa red knots during the fall migration period, serving as an important southbound stopover site in the New England portion of the subspecies' range. Additionally, this location consistently supports large concentrations of migrating rufa red knots annually due to the large intertidal areas and beach habitat that provides multiple foraging and roosting habitat areas for the birds to build energy resources for migration.

Threats identified within Unit MA–1 include disturbance of foraging and roosting rufa red knots by humans and human activities including but not limited to, pets and domestic animals, off-road vehicles (ORVs), powered and unpowered boats, surf kites, and surf fishing, predation (especially by migrating raptors and owls), possible modification or loss of habitat ( i.e., dredging), and natural or human-caused disasters ( i.e. hurricanes, oil spills). Special management considerations or protection measures to reduce or alleviate the threats may include managing access to rufa red knot foraging habitat and adjacent saltmarsh and upland roosting habitat during migration (through restrictions on timing, locations, and types of activities), and addressing the impacts of potential oil spills through protective spill response plans and training (see Special Management Considerations or Protection in the 2021 proposed rule). The National Park Service (NPS) lands within the unit ( i.e., Cape Cod National Seashore) are managed under a comprehensive shorebird management plan (NPS 2018, entire).

Unit MA–2: Pleasant Bay

Unit MA–2 consists of approximately 4,959 ac (2,007 ha) of highly dynamic barrier beaches and intertidal areas in the towns of Chatham and Orleans in Barnstable County, Massachusetts. The unit includes exposed intertidal flats, shoals, mudflats, and intertidal salt marsh pannes in Little Pleasant Bay and Pleasant Bay, and ephemeral tidal pools, primary sand dunes, and beaches associated with Nauset Beach South (Orleans), North Beach (Chatham), and North Beach Island (Chatham). The unit begins at the northeastern end of Little Pleasant Bay going east to the edge of the saltmarsh, continuing south on the interior of Nauset Beach South approximately 1.7 mi (2.7 km) then east to MLLW on the east side of Nauset Beach South, continuing south along Nauset Beach South and North Beach to North Beach Island at MLLW and terminating at the natural channel between North Beach Island and South Beach Island (Chatham). The western side of the unit runs offshore of the mainland, west of small islands in Pleasant and Little Pleasant Bays (Little Sipson Island, Strong Island, and Tern Island) and east of Hog Island and Sampson Island, incorporating intertidal lands associated with the islands. Lands within this unit include approximately 126 ac (51 ha; 3 percent) in Federal ownership, 2,005 ac (812 ha; 40 percent) in private/other ownership, and 2,827 ac (1,144 ha; 57 percent) that are uncategorized. General land use within this unit is primarily recreational, including offshore and surf fishing, shellfish digging (both recreational and commercial), boating, over-sand vehicle use, sunbathing, swimming, and walking.

Unit MA–2 is occupied by the species and contains one or more of the physical or biological features essential to the conservation of the species. The unit contains a high concentration of rufa red knots during the spring and fall migration periods, serving as an important northbound and southbound stopover site in the New England portion of the subspecies' range. Additionally, this location consistently supports a few thousand migrating rufa red knots due to the large intertidal areas and beach habitat that provides multiple foraging and roosting habitat areas for the birds to build energy resources for migration.

Threats identified within Unit MA–2 include disturbance of foraging and roosting rufa red knots by humans and human activities including but not limited to, pets and domestic animals, ORVs, powered and unpowered boats, surf kites, and surf fishing, predation (especially by migrating raptors and owls), possible modification or loss of habitat ( e.g., dredging or mining of sand flats), and natural or human-caused disasters ( i.e., oil spills). Special management considerations or protection measures to reduce or alleviate the threats may include managing access to rufa red knot foraging habitat and adjacent saltmarsh and upland roosting habitat during migration (through restrictions on timing, locations, and types of activities), and addressing the impacts of potential oil spills through protective spill response plans and training (see Special Management Considerations or Protection in the 2021 proposed rule). The National Park Service (NPS) manages Cape Cod National Seashore under a comprehensive shorebird management plan (NPS 2018, entire) (Shorebird Plan). However, due to the small and isolated nature of NPS inholdings in this unit, these areas are not actively managed under the Shorebird Plan.

Unit NY–2: Old Inlet

Unit NY–2 (Old Inlet) consists of 1,781 ac (721 ha) of highly dynamic beach, sand flats, bay islands, back bay shoreline, intertidal areas, and surface water within the town of Brookhaven, Suffolk County, New York. The unit is irregularly shaped and bounded to the south by the Atlantic Ocean, to the west by the Fire Island National Seashore's Federal Otis G. Pike Wilderness Area, and to the east by the continuation of the Federal wilderness area. Its northern boundary lies approximately in the lower third of Bellport Bay. Additionally, portions of the northern and southern areas of the unit are not contiguous, as they are separated by a vegetated dune and washover areas. Lands within this unit include approximately 1,481 ac (599 ha; 83 percent) in Federal ownership; 232 ac (94 ha; 13 percent) in State ownership; and 67 ac (27 ha; 4 percent) in private/other ownership (including the town of Brookhaven). General land use within this unit is recreational activities ( e.g., fishing, bird watching, boating, open space use). Coastal engineering structures are absent, but beach nourishment programs are implemented along the ocean beach to the east by the U.S. Army Corps of Engineers at Smith Point County Park (via coordination and agreements with the State of New York and Suffolk County).

Unit NY–2 is occupied by the species and contains one or more of the physical or biological features essential to the conservation of the species. This unit contains a high concentration of rufa red knots during the fall migration period, serving as an important southbound stopover site. The area has a relatively undeveloped character that provides protection from intensive human uses. Episodic storm events have also contributed to habitat creation, and, in turn, optimal rufa red knot habitat conditions. The bay islands and associated wetlands are managed for wildlife, which provides some limits to the amount of disturbance that rufa red knots or their habitat may experience from recreation and other human activities ( e.g., commercial shell fishing, dredging, and shoreline dock/pier projects).

Threats identified within Unit NY–2 include: (1) Sea level rise; (2) coastal engineering activities ( e.g., beach nourishment that could remove habitat, preclude the formation of habitat such as exposed shoals, and impact adjacent shoreline habitats by altering currents and sediment transport/deposition patterns); (3) predation in nonbreeding areas; and (4) human disturbance ( e.g., recreational fishing and driving, and motorized boat traffic or aircraft that create noise disturbance). Special management considerations or protection measures to reduce or alleviate the threats may include reducing disturbance ( e.g., humans, pets, vehicles, and watercraft), conducting predator control, and implementing conservation measures that help reduce modification or loss of habitat from soft beach stabilization efforts ( e.g., time-of-year restrictions for beach nourishment and dredging activities, establishing temporary sanctuaries and management during certain times of year to address erosion) (see Special Management Considerations or Protection in the 2021 proposed rule).

The town of Brookhaven lands (both marine and estuarine habitats within this unit) are managed in cooperation with the New York State Wildlife Action Plan (New York State Department of Environmental Conservation 2015, entire). Additionally, the designated South Shore Estuary Reserve implements a Comprehensive Management Plan (South Shore Estuary Reserve Council 2001, entire), which encompasses Units NY–1, NY–2, and NY–3, and serves as a guidance document for municipalities and private/public sectors to conserve or protect habitats and waters within the Reserve. Unit NY–2 is within the boundaries of the Fire Island National Seashore's Federal Otis G. Pike Wilderness Area. The NPS prepared the “Fire Island National Seashore Wilderness Breach Management Plan/Environmental Impact Statement” to provide a thorough evaluation to determine the potential benefits and consequences of management strategies prior to making a decision on how to manage the wilderness breach (NPS 2017, entire).

Unit NJ–1: Brigantine and Little Egg Inlets

Unit NJ–1 consists of 9,952 ac (4,027 ha) of beach, dune, shoals, open water, and tidal marsh associated with two inlets ( i.e., small arms of the ocean) in Ocean and Atlantic Counties, New Jersey, extending from the northern boundary of the Holgate Unit of Edwin B. Forsythe (Forsythe) NWR, west to the “Seven Islands” portion of Great Bay Boulevard Wildlife Management Area, and south nearly to 15th Street North in Brigantine City. To the north, the unit encompasses the Holgate Unit of the Forsythe NWR and includes several areas within the Great Bay Boulevard Wildlife Management Area, owned by the State of New Jersey ( e.g., Seven Islands and other islands on either side of Great Bay Boulevard south of Big Sheepshead Creek). The unit also includes portions of Little Beach Island within the Forsythe NWR, and portions of the North Brigantine Natural Area owned by the State of New Jersey. This unit includes extensive areas of shoals and sand or mud flats (such as the new island east of Little Beach Island that is within the Edwin B. Forsythe NWR), which are generally owned by the State. Lands within this unit include approximately 1,560 ac (632 ha; 16 percent) in Federal ownership, 3,187 ac (1,291 ha; 32 percent) in State ownership, 10 ac (4 ha; less than 1 percent) in private/other ownership, and 5,194 ac (2,101 ha; 52 percent) that are uncategorized. General land use within this unit is almost entirely undeveloped and managed for wildlife and other natural resource values, as well as recreation.

Unit NJ–1 is occupied by the species and contains one or more of the physical or biological features essential to the conservation of the species. This unit contains a high concentration of rufa red knots during the spring and fall migration periods, serving as an important northbound and southbound stopover site. This unit has an undeveloped character that provides protection from intensive human uses. The lack of hard structures and other coastal engineering practices in this unit allows optimal rufa red knot habitat conditions to be created and maintained by natural coastal processes, which is a condition that is rare in the mid-Atlantic. The Little Egg Inlet is the only unmodified inlet in New Jersey and one of only two unmodified inlets between Montauk, New York, and Chincoteague, Virginia, a shoreline distance of nearly 350 mi (563 km) (Rice 2016, pp. 24–25). Nearly all the lands in the unit are managed for wildlife, which limits disturbance of rufa red knots from recreation and other human activities.

Threats identified within Unit NJ–1 include: (1) Sea level rise that may accelerate faster than landforms can migrate through natural coastal processes; (2) coastal engineering activities ( e.g., ongoing updrift beach nourishment; proposed enlargement of a terminal groin immediately adjacent to the unit's northern limit; ongoing and proposed dredging that could remove habitat ( e.g., exposed shoals), preclude habitat formation, and/or impact adjacent shoreline habitats by altering sediment transport/deposition patterns); (3) aquaculture leases; (4) predation in nonbreeding areas; and (5) human disturbance ( e.g., recreational fishing and driving in the fall, motorized boat traffic and aircraft year round). Special management considerations or protection measures to reduce or alleviate the threats may include managing sources of disturbance ( e.g., humans, pets, vehicles, and watercraft), managing predator populations, and implementing conservation measures to abate habitat impacts from coastal engineering projects and from sea level rise (see Special Management Considerations or Protection in the July 15, 2021, proposed rule). Federal lands in this unit are managed under the Edwin B. Forsythe NWR Comprehensive Conservation Plan (Service 2004a, entire). State lands within the North Brigantine Natural Area are covered by a Beach Management Plan (Service and New Jersey Department of Environmental Protection 2019, entire).

Unit VA–12: Ship Shoal Island

This unit consists of a total of 2,426 ac (982 ha) in Northampton County, Virginia, including both Ship Shoal Island and the area known as Godwin Island. The north boundary is Red Drum Drain and New Inlet, the south boundary is Ship Shoal Inlet, the west boundary is South Bay, and the east boundary is the Atlantic Ocean. The boundary for the island and marsh complex extends outward past the MLLW line and includes the areas that are slightly inundated with less than 3 in (7.6 cm) of water. The unit is composed of 426 ac (172 ha; 18 percent) in State ownership, 1,941 ac (785 ha; 80 percent) in private/other ownership, and the remaining 60 ac (24 ha; 2 percent) is uncategorized. The island is composed of extensive mud flats, low marsh, sandy beaches, overwash areas, and tidal channels. General land use within this unit is scientific research ( e.g., surveys and monitoring for nesting shorebirds); this area is closed to visitor use at all times for scientific research and safety reasons (TNC 2017, p. 1).

Unit VA–12 is occupied by the species and contains one or more of the physical or biological features essential to the conservation of the species. This unit is essential to the conservation of the species because it is used by rufa red knots in conjunction with other proposed critical habitat units with large concentrations of rufa red knots observed during the spring migration season and provides high-quality habitat that is protected from disturbance. Additionally, rufa red knots are known to move from island to island daily within the barrier island chain; the whole chain of islands serves as important foraging and roosting habitat for the rufa red knot. Therefore, inclusion of unit VA–12 accurately captures how rufa red knots are using the available habitat along Virginia's Eastern Shore.

The threats identified within Unit VA–12 include: (1) Natural ( e.g., hurricanes) or human-caused ( e.g., oil spills) disasters, and (2) erosional processes and accelerated loss of shoreline habitat in response to climate change and sea level rise. Special management considerations or protection measures to reduce or alleviate the threats may include managing scientific research activity access to rufa red knot foraging habitat and adjacent upland roosting habitat during migration, and establishing temporary sanctuaries and management during certain times of year to address erosion (see Special Management Considerations or Protection in the 2021 proposed rule). The island is owned and managed by TNC as part of the Virginia Coast Reserve, management of which is identified in a Conservation Action Plan that outlines priorities and strategies for conservation activities (Wilke 2020, pers. comm.).

Unit VA–15: Fisherman Island

This unit consists of a total of 2,413 ac (977 ha) in Northampton County, Virginia. The unit is an oval-shaped island located at the mouth of the Chesapeake Bay and is just south of the tip of the Eastern Shore peninsula. The island is surrounded by the waters of the Chesapeake Bay and Atlantic Ocean. It is bisected by U.S. Route 13 and the Chesapeake Bay Bridge–Tunnel complex. The interior boundary is along the dune line where the habitat changes from sandy beach with little vegetation to densely vegetated dunes or marshland, as well as densely vegetated forested or herbaceous vegetation landward of the beach and primary dune. The unit extends seaward past the MLLW line and includes areas that are slightly inundated with less than 3 in (7.6 cm) of water. The unit is federally owned by the Service's Eastern Shore of Virginia NWR. General land use within this unit includes low-impact recreational day use ( e.g., hiking, bird watching, photography) only provided through guided tours from September through February. In addition, scientific research ( e.g., survey and monitoring of natural resources, such as federally listed species) may occur year-round.

Unit VA–15 is occupied by the species and contains one or more of the physical or biological features essential to the conservation of the species. This unit is essential to the conservation of the species because it is used by rufa red knots in conjunction with other proposed critical habitat units with large concentrations of rufa red knots observed during the spring migration season and provides high-quality habitat that is protected from disturbance. Additionally, rufa red knots are known to move from island-to-island daily within the barrier island chain; the whole chain of islands serves as important foraging and roosting habitat for the rufa red knot. Therefore, inclusion of unit VA–15 accurately captures how rufa red knots are using the available habitat along Virginia's Eastern Shore.

Threats identified within Unit VA–15 include: (1) Disturbance of foraging and roosting rufa red knots by trespass recreational beach use, (2) natural ( e.g., hurricanes) or human-caused ( e.g., oil spills) disasters, and (3) accelerated loss of shoreline habitat from erosional processes in response to sea level rise. Special management considerations or protection measures to reduce or alleviate the threats may include managing access to rufa red knot foraging habitat and adjacent upland roosting habitat during migration (through restrictions on timing, locations, and types of activities), and establishing temporary sanctuaries and management during certain times of year to address erosion (see Special Management Considerations or Protection in the 2021 proposed rule). Currently, Eastern Shore of Virginia and Fisherman Island NWRs address some of these threats in their Comprehensive Conservation Plan (Service 2004b, entire) and Habitat Management Plan (Service 2018, entire).

Executive Order 12866 provides that the Office of Information and Regulatory Affairs (OIRA) in the Office of Management and Budget will review all significant rules. OIRA has determined that this revised proposed rule is significant.

Executive Order 13563 reaffirms the principles of Executive Order 12866 while calling for improvements in the nation's regulatory system to promote predictability, to reduce uncertainty, and to use the best, most innovative, and least burdensome tools for achieving regulatory ends. The executive order directs agencies to consider regulatory approaches that reduce burdens and maintain flexibility and freedom of choice for the public where these approaches are relevant, feasible, and consistent with regulatory objectives. Executive Order 13563 emphasizes further that regulations must be based on the best available science and that the rulemaking process must allow for public participation and an open exchange of ideas. We have developed this revised proposed rule in a manner consistent with these requirements.
