Jornada Experimental Range Quadrants
Listed in NASA Earthdata CMR
The "Jornada Experimental Range Quadrats" data contains reduced-scale maps of vegetation on one-meter by one-meter areas were made with a pantograph.
Description
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 Experimental Range near Las Cruces, New Mexico Collection Organization: Jornada Experimental Range Collection Methodology: Reduced-scale maps of vegetation on 1m by 1m areas were made with a pantograph. A planimeter was used to measure basal area of grasses and canopy cover of shrubs and this was recorded on maps.
