Dataset: Herbaceous Vegetation Data from Grasshopper Study Plots on the Jornada Experimental Range,1983-1985


   File description including attribute definitions: data_JornadaStudy_370_grasshopper_plot_vegetation ,    File description including attribute definitions: Plant Species Codes
   Original Investigator: David Lightfoot
   Duration: 1983 - 1985
   Dataset ID: 210370002
   DOI: 10.6073/pasta/ff5037b4a87a2f3ff13131f1acb55bed
   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.


   Methods:

field data sheets

   Methods:

One square-meter PVC pipe frame was placed  in NE corner of each quadrat (see abstract). All herbaceous plant species present in frame were recorded, including estimations of mean diameter (cm), height (cm), and total number of individuals for each species.See accompanying file, Study_370_plantspeciescodes.csv, for the species code list.

   Maintenance:

May, July, September from 1983-1985
