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. 166 over West Prong Roaring River on SR 1745
in Wilkes County, TIP No. BR-0124.
The North Carolina Department of Transportation (NCDOT, Division 11) proposes to
replace Bridge No. 166 over West Prong Roaring River on SR 1745 in Wilkes County, TIP
No. BR-0124. The existing bridge is a three span structure with steel plank deck, steel I -
beams, timber end walls and metal guard rails. The overall length of the structure is 136
feet.
Northern long-eared bat
The project to replace Bridge No. 166 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/nccounties.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 1/4 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 42 miles west
of the project and no known NLEB roost trees occur within 1SO feet of the project
area.
NCDOT has also reviewed the USFWS Asheville Field office website
(httl2://www.fws.gov/asheville/htmIs/12roject 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. 166 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 (metal and steel) 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. 166 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 74 miles
west of the project site. In September 2019, a gray bat was found roosting in a bridge in
Surry County 24 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
metal 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 (metal
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.
