Data from: Evapotranspiration response to multiyear dry periods in the semiarid western United States

Joseph Rungee, Roger Bales, Michael Goulden, Gerald Flerchinger, Greg Barron-Gafford & Xiande Meng
Analysis of measured evapotranspiration shows that subsurface plant‐accessible water storage (PAWS) can sustain evapotranspiration through multiyear dry periods. Measurements at 25 flux tower sites in the semiarid western United States, distributed across five land cover types, show both resistance and vulnerability to multiyear dry periods. Average (±standard deviation) evapotranspiration ranged from 660 ± 230 mm yr−1 (October–September) in evergreen needleleaf forests to 310 ± 200 mm yr−1 in grasslands and shrublands. More than 52% of...

Multi-scale drivers of soil resistance predict vulnerability of seasonally wet meadows to trampling by pack stock animals in the Sierra Nevada, USA

Joy S. Baccei, Mitchel P. McClaran, Tim J. Kuhn & Stephen C. Hart
Background Meadow ecosystems have important ecological functions and support socioeconomic services, yet are subject to multiple stressors that can lead to rapid degradation. In the Sierra Nevada of the western USA, recreational pack stock (horses and mules) use in seasonally wet mountain meadows may lead to soil trampling and meadow degradation, especially when soil water content is high and vegetation is developing. Methods In order to improve the ability to predict meadow vulnerability to soil...
