USGS FORT - Rocky Mountain Arsenal National Wildlife Refuge - Bats - 1997-1998

Study Extent

In 1997 and 1998, we used mist nets to capture bats and to 1) determine local species richness and relative abundance, 2) establish roosting habits and locations , and 3) collect bats to evaluate organochlorine contaminant levels in local bats.

Sampling

Nets were set along drainage canals, across small ponds and edges of lakes, and perpendicular to patches of treees and shrubs; all were set at or near ground or water level. The nets were set from sunset to midnight and monitored continuously.

Quality Control

We reviewed and verified that the values used in the dataset represent the correct range of values (e.g., sex=male or female). All data was reviewed for completeness and accuracy prior to publishing the results. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. A formal accuracy assessment of the vertical positional information in the data set has not been conducted.

Method steps
