Small mammal trapping (LTER-II)

Small mammal live-traps are located on consumer pitfall
plots. A grid of 20 traps is located on each consumer plot.
Small mammals are trapped daily for a one-week period in the late
spring and again in the late summer of each year. Data on
species, sex, toe marks, weight, and reproductive condition are
taken.

Pitfall trap grids have been installed at three creosotebush
sites, three grassland sites, three mesquite sites, and two tarbush
sites. Jornada LTER II consumer plots during this period were
located at T-WEST, T- EAST, M-RABB (2 grids), M-WELL, G-IBPE (2
grids), G-BASN, C-SAND (2 grids), and C-CALI sites.
