Spring and Fall plant cover across grassland-shrubland ecotones at 3 sites in the Jornada Basin, 2005-ongoing

The objective of this ongoing study is to investigate how pulses of
precipitation translate into pulses of plant aboveground net primary
productivity (ANPP) across grassland to shrubland ecotones in the
northern Chihuahuan Desert. This dataset consists of ocular plant
cover and height measurements to be used for estimating aboveground
net primary in three habitat vegetation zones (grassland, ecotone,
and shrubland) at three grassland-to-shrubland ecotone sites in the
Jornada Basin, Dona Ana County, New Mexico, USA. Sampling is
conducted twice a year: in the spring before the growing season and
in the fall after the growing season.
