Summary

Explore climate change impacts on vegetation across the Desert and Southern Rockies LCCs using historical monitoring data collected from 23 sites across the Sonoran, Chihuahuan, Mojave and Colorado Plateau deserts for 30-50 years. This data will then be combined with ecosystem water balance model simulations to establish features of water availability critical for plant species response. Results will allow managers to identify species and communities at risk under future climate scenarios based on predicted changes in plant water availability. Due to the high variability in soils, incorporating a detailed understanding of soil water availability beyond bioclimatic envelope approaches in the desert Southwest is essential to accurately [...]

Purpose

Overall goal is to understand how climate change will impact desert vegetation from a hydrological perspective. To accomplish this goal, we have the following specific objectives: 1) Simulate water balance and availability at long-term vegetation monitoring plots. 2) Compare the model output with observed vegetation patterns to identify the features of water availability that are crucial for plant species responses. 3) Assess the vulnerability/sustainability of individual plant species and functional types by simulating site-specific water balance and availability under future climate scenarios. 4) Create ecosystem-specific applied science tools to allow managers to identify species and communities at risk under future climate scenarios based on predicted changes in plant water availability.
