Data for arthropods captured in pitfall traps on LTER II
consumer plots. Data includes order, family, genus,
species, and number.

Methods: 

field data sheets

A grid of 16 pitfall traps is located at each consumer
plot. Each trap is 40 cm deep and contains an inner plastic
container and funnel. A ceramic tile is placed over each
trap. For a 2-week period each month, from 16 June 1989 to
23 August 1991, the tiles were raised on one side, and the
traps are checked every 3 days in summer and once a week in
winter. For the period post-August 1991, the traps are
opened for 2 consecutive weeks on a quarterly basis (Feb,
May, Aug, Oct). The arthropods in the inner containers are
all combined to one container for each plot, brought to the
lab, preserved, and sorted to taxa. Non-ground dwelling
arthropods are released in the field. Large long-lived
arthropods such as tarantulas are recorded and released in
the field. See PITFALL.PRO file for detailed protocol.

Quality assurance: 

Data is entered from field data sheets using LOTUS 123
add-in called D.A.V.E. which is a data entry and
verification program.
