Title:Herbaceous Vegetation Data from Grasshopper Study Plots on the Jornada Basin LTER,1984-1985
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This data on annual herbaceous plants was measured on Jornada grasshopper study plots located on the east bajada of the Dona Ana Mts. Three plots were situated on the bajada parallel to and 200m south of the LTER transect. Two additional sets of three plots were located 5km and 10km south of the LTER transect. Each plot was composed of two 50m belt transects, each divided into ten 5m2 quadrats. Annual plants were measured in the NE 1m2 of each quadrat, once in May, July and September in 1983, 1984 and 1985. All individuals of each species were counted and measured. A mean diameter, height, and the total number of individuals/1m2/quadrat were recorded. This study is complete.
