Location and Habitat
Location Accuracy (meters):
0-25
Habitat Type:
Riparian - Areas Along lake or stream
Habitat Type Notes:
Creek bed was dry, allowing us to easily traverse the rocky substrate, bank to bank. Surrounding riparian area was primarily medium-sized trees, such as oaks, hackberry, dogwood, with some understory of various (primarily native) forbs and grasses like Chasmanthium latifolium and Malvaviscus arboreus.

Light Trespass (light cast on surfaces beyond its intended target): Yes
Glare (bright light causing visual discomfort): Yes
Artificial Light Notes:
Most of the survey area was under fairly thick tree canopy with some ground cover to buffer light from nearby homes, but these provided some glare/trespass - some very bright - as one travels up and out of the creek bed. The trail we used to access the creek bed did not have any light sources directly on it.
