Projected water deficits mean that land and water managers must be proactive in their management of rivers and shallow aquifers, if they want to maintain the ecosystems dependent upon them. To do this, managers and decision makers need easy access to the best techniques available for determining how much water ecosystems need. This project will result in a Desert LCC-wide database of environmental flow needs and responses (environmental water demands) to help water and land managers make management decisions. This project will identify critical data gaps in flow need and flow response data in the Desert LCC (especially related to baseflow dependent streams) and result in a user-friendly, one-stop-shop for managers...

In regulated rivers of the southwest, reduced flooding and the invasion of tamarisk contributes to accumulation of greater fuel loads and increased riparian fire frequency. As a result, some desert riparian areas, historically considered barriers to wildfire, have been converted into pathways for wildfire spread. Fire-smart management strategies are needed to protect sensitive riparian species and reduce fire risk from increased fire frequency due to interactions of climate change, tamarisk invasion, and tamarisk beetle activity. Fire niche simulations will be used to project impacts of fire frequency and climate change, which can be used to highlight areas of the Desert LCC where Southwestern Willow Flycatcher,...

Accurate estimation of evapotranspiration (ET) is essential for assessments of water balance and hydrologic responses to forest restoration treatments in uplands adjacent to the Desert LCC. As part of the Four Forests Restoration Initiative, a new paired watershed study is being planned to assess the hydrologic effects of mechanically thinning and restoring a more frequent fire regime to the ponderosa pine forests of Arizona. Water and energy balances will be measured and modeled in these paired watersheds to help inform and better plan for the hydrologic responses of future forest restoration actions. Researchers at Northern Arizona University have collected six years of eddy covariance measurements of ET in the...

The U.S. Forest Service plans to conduct forest restoration treatments through the Four Forest Restoration Initiative (4FRI) on hundreds of thousands of acres of ponderosa pine forest along the Mogollon Rim of Arizona over the next 20 years with the goals of reducing wildfire hazard and improving forest health. The 4FRI’s key objective is to thin and burn the forests to create within-stand openings that “promote snowpack accumulation and retention which benefit groundwater recharge and watershed processes at the fine (1 to 10 acres) scale.” However, little is known about how these openings created by restoration treatments affect snow water equivalence (SWE) and soil moisture, which are key parts of the water balance...

The substantially natural hydrography of the upper Gila River supports one of the highest levels of aquatic and riparian biodiversity in the region, including the largest complement of native fishes and some of the best remaining riparian habitat in the lower Colorado River Basin. Native vegetation dominates the broad and structurally diverse floodplain, creating habitat for hundreds of birds and other wildlife. Two of the Gila’s fish species, spikedace and loach minnow, and a neotropical migratory bird, the southwestern willow flycatcher, are federally listed as endangered. The yellow-billed cuckoo, a candidate species for listing, nests in the Cliff-Gila Valley. Changes to the river’s hydrology, including peak...

Northern Arizona University will build upon the U.S. Forest Service Four Forest Restoration Initiative in Northern Arizona to investigate how restoration efforts can affect the water volume available in the snowpack and soil moisture in the Desert LCC. This project will result in a tool that can be used to predict the water volume in snowpack and soil moisture response to various forest treatments.

Riparian vegetation provides crucial habitat for wildlife and is a high conservation priority for land managers throughout the Southwest but a central scientific challenge is to generate quantitative predictions of how changes in water availability will affect the amount and quality of riparian wildlife habitat. Researchers will study areas that have long-term datasets available (i.e., hydrological, geomorphological, biological), that characterize a broad range of riparian conditions found in the Southwest. Building on recently developed models funded by the USGS National Climate Change and Wildlife Science Center (NCCWSC), this work will link various hydrologic, geomorphic and habitat models to better understand...
