January 14, 2020 TO: Michael Turchy, ECAP Western regional Team Lead Environmental Coordination & Permitting Group, EAU FROM: Melissa Miller, Environmental Program Consultant Biological Surveys Group, EAU SUBJECT: Section 7 survey results for the northern long-eared bat (Myotis
septentrionalis) and gray bat (Myotis grisescens) associated with the replacement of Bridge No. 04 over Little Hunting Creek on SR 2418 in Wilkes County, TIP No. BR-0108. The North Carolina Department of Transportation (NCDOT, Division 11) proposes to replace Bridge No. 04 over Little Hunting Creek on SR 2418 in Wilkes County, TIP No. BR-0108. The existing bridge is a single span structure with steel beams, timber deck and end walls, and metal guard rails. The overall length of the structure is 41 feet. Northern long-eared bat The project to replace Bridge No. 04 has been reviewed for effects on the northern long-eared bat (NLEB). As of May 4, 2015, NLEB is listed by the U.S. Fish and Wildlife Service (USFWS) as “Threatened” under the Endangered Species Act of 1973. As of January 14, 2020, NLEB is listed by USFWS (http://www.fws.gov/raleigh/species/cntylist/nc_counties.html) as “current” in Wilkes County. USFWS also established a final rule under the authority of section 4(d) of the Endangered Species Act that provides measures for the conservation of NLEB. The USFWS has tailored the final 4(d) rule to prohibit the take of NLEB from certain activities within areas where they are in decline. This incidental take protection applies only to known NLEB occupied maternity roost trees and known NLEB hibernacula. Effective February 16, 2016, incidental take resulting from tree removal is prohibited if it 1) occurs within a ¼ mile radius of known NLEB hibernacula; or 2) cuts or destroys known occupied maternity roost trees or any other trees within a 150-foot radius from the known maternity tree during the pup season (June 1-July 31).

According to the North Carolina Natural Heritage Program (NHP) Biotics Database, most recently updated October 2019, the nearest NLEB hibernacula record is 46 miles west
of the project and no known NLEB roost trees occur within 150 feet of the project
area. NCDOT has also reviewed the USFWS Asheville Field office website (http://www.fws.gov/asheville/htmls/project_review/NLEB_in_WNC.html) for consistency with NHP records. This project is located entirely outside of the red highlighted areas (12-digit HUC) that the USFWS Asheville Field Office has determined to be representative of an area that may require consultation. For the proposed action, NCDOT has committed to the conservation measures listed below: 1) No alterations of a known hibernacula entrance or interior environment if it impairs an essential behavioral pattern, including sheltering northern long-eared bats (January 1 through December 31); 2) No tree removal within a 0.25-mile radius of a known hibernacula (January 1 through December 31); and 3) No cutting or destroying a known, occupied maternity roost tree, or any other trees within a 150-foot radius from the known, occupied maternity tree during the period from June 1 through and including July 31.
NCDOT has determined that the proposed action does not require separate
consultation on the grounds that the proposed action is consistent with the final
Section 4(d) rule, codified at 50 C.F.R. § 17.40(o) and effective February 16, 2016. NCDOT may presume its determination is informed by best available information and consider Section 7 responsibilities fulfilled for NLEB.
This project was originally state funded and was therefore evaluated on August 13, 2019.
NCDOT biologists assessed Bridge No. 04 for potential northern long-eared bat habitat. No
shallow vertical top sealed crevices or deep vertical unsealed crevices suitable for roosting
were present on the structure. No evidence (bats, staining, and guano) of bats was observed.
Based on the type of bridge and lack of evidence of bats on the bridge, NCDOT recommends a
biological conclusion of No Effect for the northern long-eared bat. Gray Bat The project to replace Bridge No. 04 has also been reviewed for effects on the gray bat (MYGR). As of April 28, 1976, the gray bat was listed by the U.S. Fish and Wildlife Service (USFWS) as “Endangered” under the Endangered Species Act of 1973. According to the USFWS Wilkes County webpage (accessed January 14, 2020), (http://www.fws.gov/raleigh/species/cntylist/nc_counties.html), the gray bat is listed by USFWS as “probable/potential” in Wilkes County.

According to the North Carolina Natural Heritage Program (NHP) Biotics Database, most recently updated in October 2019, MYGR have not been documented in Wilkes County. NHP data indicate that the closest known occurrence of MYGR is approximately 78 miles
west of the project site. In September 2019, a gray bat was found roosting in a bridge in Surry County 26 miles east of the project (personal correspondence). As of this writing, the Surry County occurrence is not yet reflected in the NHP Biotics Database. On November 13, 2019 the gray bat was added as a listed species potentially occurring in Wilkes County. This listing occurred after the survey window for bats (May 15-August 15) had closed. On January 9, 2020, NCDOT biologists assessed the bridge project footprint for potential MYGR habitat. No evidence of bats (bats, staining or guano) was observed on this small, timber deck and steel beam bridge. No shallow vertical top sealed crevices or deep vertical unsealed crevices suitable for roosting were present on the structure. No caves or mines are located within the project footprint or within line of sight of the bridge. Therefore, no suitable roosting habitat for MYGR is present. Based on the lack of evidence of bats during the recent bridge inspection and the prior August 13 field visit, the type of bridge (timber and steel) and lack of caves or mines in the project vicinity, the proposed project will have a biological conclusion of No Effect for gray bats.
