Executive Summary: Riparian ecosystems are vital components of the semi-arid landscape because woody riparian plants provide resources that are absent in adjacent vegetation types. Historically, flood played a key role in shaping the composition and structure of riparian forests. In recent decades, however, the frequency and magnitude of floods has decreased and the timing of peak discharge has been altered. In addition, wildfire has increased in importance as an agent of disturbance along many streams. We initiated this study to increase our understanding of fire, flood, and drought processes at our Middle Rio Grande study sites and develop tools that managers of other systems can use to project the response of...

University of Arizona will conduct an ecosystem conservation assessment for the lower San Pedro (LSP) watershed. The assessment will provide a science-based strategic design for prioritizing where conservation efforts are most needed for high-value biodiversity conservation at the landscape-level and offer insights on conservation actions practical for implementation. The assessment will include an evaluation of high-value biodiversity, hydro-ecological processes, protected areas, landscape connectivity, and climate change adaptation. The study will suggest approaches for developing a new conservation framework for watershed conservation planning.

Perennial streams in the Desert LCC support riparian trees such as cottonwood (Populus spp) and box elder (Acer negundo) that are critical components of habitat for riparian obligate birds and other wildlife species (Webb et al. 2007). Trees, snags, and fallen woody debris provide nesting and foraging sites for a variety of riparian animals (Bateman et al. 2008, Smith et al. 2012). Riparian trees require occasional floods to create space suitable for germination and are dependent on accessible groundwater for growth and survival (Lytle and Merritt 2004). Studies along the Middle Rio Grande in New Mexico have shown that rates of woody debris accumulation are also influenced by hydrology because floods physically...
