We don't have any major concerns; however, we have a few recommendations for the Line 333 Retrofit project in
Randolph County.
• The state special concern Greensboro burrowing crayfish (Cambarus catagius) has been documented in
Randolph County; however, the full extent of its distribution in this watershed is unknown due to lack of
targeted surveys. We request site inspections for the Greensboro burrowing crayfish. We have included an
information sheet on preliminary site inspections for this species. Please notify Brena Jones, Central Aquatic
Wildlife Diversity Coordinator ([e-mail], 919-707-0369), if any potential Greensboro
burrowing crayfish or burrows are located.
• Stringent erosion and sedimentation control measures should be installed prior to any land -disturbing activity
and maintained throughout the entire project. Ensure the temporary bridges do not impact the form and
function of streams and if needed, the banks should be stabilized once bridges are removed.
• During construction, equipment should not be staged in stream channels or riparian buffers.
• We recommend not using heavy, tracked equipment in wetlands but rather use hand tools if possible, and leave
downed trees and shrubs so the wetland is not damaged by heavy equipment.
• All mechanized equipment operated near surface waters should be inspected and maintained regularly to
prevent contamination from fuels, lubricants, hydraulic fluids or other toxic materials.
• Ensure all silt fencing is removed once vegetation has reestablished and soils have stabilized.
• Avoid the removal of large trees at the edges of construction corridors. Re -seed disturbed areas with native
seed mixtures that are beneficial to wildlife. Avoid fescue -based mixtures and lespedeza as these species are
non-native and/or invasive.
Please let me know if you have questions. Thanks,
Olivia

Burrowing Crayfish Preliminary Site Inspection
RESOURCES
COMMISSION
The NC Wildlife Resources Commission (NCWRC) is seeking information on the Greensboro Burrowing Crayfish (GBC;
Cambarus catagius), a rare endemic species and state listed as Special Concern. We are requesting assistance from
consultants and other workers in the field to help identify sites in the permit review process which may have
populations of GBC. This entails simply looking for signs of activity (details below) while you are already on the property.
This may assist both the applicant and NCWRC with a more efficient project review. NCWRC is also interested in
expanding and updating the understanding of GBC distribution and biology.
While walking the property, look for signs of burrowing crayfish activity. This may include entrance holes in the ground
or in the banks/sides of ditches and streams, approximately 1-3" in diameter, or crayfish (photos on pg. 2). Greensboro
Burrowing Crayfish are not currently known to build chimneys at burrow entrances but have been found near other
chimney -building species.
This species does not require flowing surface water and can dig extensive burrows over 4' deep, so they can be found in
lawns or even dirt floors of garages or outbuildings.
If an inspection for crayfish is conducted, please note:
• How much and which portion of the property was inspected and by whom.
• If signs of activity are seen, please make note of where they are. Photographs are welcome.
• If no activity is seen after a targeted inspection, please note that information as well.
Include this information with permit application materials. If signs of burrowing crayfish activity are noted, a follow-up
survey is recommended to determine whether GBC are present. If onsite staff have appropriate permits (state Scientific
Collection Permit for Endangered Species) & expertise, they may conduct the survey. Contact Olivia Munzer with the
NCWRC at [e-mail] with questions.
