Summary
Abstract:
The "Jornada Experimental Range Quadrats" data contains reduced-scale maps of
vegetation on one-meter by one-meter areas were made with a pantograph. A planimeter was used to measure the basal area of grasses and canopy cover of shrubs. This information was then recorded on maps. These data were collected to assess changes in vegetation due to precipitation and livestock grazing on the Jornada ...
