Total Annual Aboveground Net Primary Productivity across grassland-shrubland ecotones at 3 sites in the Jornada Basin, 2006-ongoing

The objective of this ongoing study is to investigate how pulses of
precipitation translate into pulses of plant aboveground net primary
productivity (NPP) across grassland to shrubland ecotones in the
northern Chihuahuan Desert. This dataset consists of annual
aboveground net primary productivity estimates 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. The annual ANPP estimates are derived from
plant cover measurements (see methods). Due to its growth form,
Yucca elata (YUEL) has been found to produce large errors in
interyear biomass estimates. This data package contains annual ANPP
estimates both with and without YUEL, but the authors strongly
recommend using the non-YUEL estimates for most purposes. Data
collection is ongoing with new observations in spring and fall of
each year; data from both annual sampling times are required to
estimate annual ANPP.
