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.本项正在开展的研究旨在探究奇瓦瓦沙漠北部草原-灌丛交错带中，降水脉冲如何转化为植物地上净初级生产力（aboveground net primary productivity, ANPP）脉冲。本数据集包含目视植被盖度与株高测量数据，用于估算美国新墨西哥州多纳阿纳县霍纳塞盆地（Jornada Basin）三处草原-灌丛交错带样点的三类植被生境带（草原带、交错带与灌丛带）的地上净初级生产力。该研究每年开展两次采样：分别为生长季前的春季，以及生长季结束后的秋季。
