2024 Research Brief
Description
Rates of tree death soared in the Sierra Nevada during the severe 2012-16 drought. While the acute effects of drought occurred over a short period, the mass mortality event kickstarted a decades-long process of snag fall, increased fuel loads, and changed fuel composition. Fuel loads, snag density, and snag fall rate were collected at two sites in Yosemite National Park (YOMI = mixed conifer site, YOPI = pine-dominated site) and one at Sequoia/Kings Canyon National Park (SEKI) and modeled to predict future fuel loads and snag fall rates.
