Structure Assessement - Emergence Count
If an emergence survey is needed, it should begin 1/2 hour before sunset and continue for an hour or until it is too
dark to see bats. Surveyors should position themselves outside so that emerging bats will be silhouetted against
the sky. Do not conduct emergence count if temp is < 50F or if there is rain.
Temperature at start of count:___________
Emergence count starting time:____________
Time of sunset:___________
Emergence count ending time:___________
Number of bats leaving structure:___________
Can bat genus/species be determined?_________
Describe where bats exited structure:________________
Comments, notes:
Provide a diagram of the structure, where observers were placed for the emergence count, and location
of any points of ingress/egress for bats. Please include a north arrow.
