Litterfall data from creosote sites along the Jornada Basin LTER transect, 1985-1988

This dataset contains measurements of litterfall from creosote shrub
communities along the Jornada Basin LTER (LTER-I) transects in
southern New Mexico, USA. These transects are located in a livestock
exclosure established in 1982 in the Chihuahuan Desert Rangeland
Research Center (CDRRC) and run from the middle of the College Playa
up to the foot of Mt. Summerford (2.7 km in length). Prior to the
exclosure, the study site was moderately to heavily grazed for the
past 100 years. The treatment transect was treated annually with
ammonium nitrate fertilizer (NH4NO3 at 10g N/m2/yr) until 1987.
Creosotebush litterfall was collected monthly from traps under ten
shrubs in the creosote zones along the control and treatment
transects. Oven-dry weights of leaves, stems, and seed fractions as
well as total dry weight of monthly collections are recorded. This
study is complete.
