Speaker: Dr. Keirith Snyder, USDA ARS, Great Basin Rangelands Research Unit, Reno, NV The opportunistic encroachment of native pinyon and juniper trees into areas formerly dominated by sagebrush has reduced the presence of shrubs and grasses, impacting critical habitat and forage availability. Pinyon and juniper currently occupy 19 million hectares in the Intermountain West. Prior to 1860, it is estimated that 2/3 of pinyon and juniper woodlands were sagebrush communities. This presentation will give an overview of the Porter Canyon Experimental Watershed, where tree-felling treatments are being studied. Porter Canyon is located in central Nevada in the Desatoya Mountains. A network of sensors has been installed...

Plant phenology is recognized as important for ecological dynamics. There has been a recent advent of phenology and camera networks worldwide. The established PhenoCam Network has sites in the United States, including the western states. However, there is a paucity of published research from semi-arid regions. In this study, we demonstrate the utility of camera-based repeat digital imagery and use of R statistical phenopix package to quantify plant phenology and phenophases in four plant communities in the semi-arid cold desert region of the Great Basin. We developed an automated variable snow/night filter for removing ephemeral snow events, which allowed fitting of phenophases with a double logistic algorithm....

This research highlights development and application of an integrated hydrologic model (GSFLOW) to a semiarid, snow-dominated watershed in the Great Basin to evaluate Pinyon-Juniper (PJ) and temperature controls on mountain meadow shallow groundwater. The work used Google Earth Engine Landsat satellite and gridded climate archives for model evaluation. Model simulations across three decades indicated that the watershed operates on a threshold response to precipitation (P) >400 mm/y to produce a positive yield (P-ET; 9%) resulting in stream discharge and a rebound in meadow groundwater levels during these wetter years. Observed and simulated meadow groundwater response to large P correlates with above average predicted...
