Birdwood Mammal Trapping Data, Charlottesville, VA, 1974-1978

This data was collected by Ray Dueser, Bob Rose and their students (among them, Marcia Wilson, John Porter and Bill Ingoly). It is included in the VCR LTER database for comparative purposes. The data itself consists of trapping records for 10x10 trapping grids with 7.6m (25 foot) trap spacing. (note: grid 5 had an unusual geometry due to size constraints). Up to 4 captures of an individual may be recorded on each line of data. Trapping used modified Fitch live traps with a #10 tin can as the main chamber. Traps were baited with cracked corn or hen scratch and run for 3 sequential nights in each trapping session. In addition to the basic trapping data, there are additional files such as a fortran program for detecting inconsistencies in the data (KCHECK.FOR), a listing of known problems (ERRORLIS), a program for calculating Minimum Number Known Alive (MNAPROG.FOR) and a file containing minimum number alive (BIRDMNA.DAT) for each grid, week, sex and species combination.
