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,...

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...

Academics & scientific researchers,
Freshwater fishes are globally among the most imperiled major biodiversity groups and they are especially endangered in the North American deserts of the vast binational Desert LCC. Sixty seven native fish species of conservation concern are in the study area, which includes all of the DLCC in both the US and Mexico. Essentially all species in our study area are understudied and management of them has been greatly impeded by the intrinsic difficulties of working internationally and by relative lack of, or inaccessibility to, basic knowledge about their distributions and conservation status. We propose to mine data from all online and known US-based institutions holding specimen-based occurrence records from our...

Applications and Tools,
The Desert Landscape Conservation Cooperative (LCC) is a partnership formed and directed by resource management entities as well as interested public and private entities in the Mojave, Sonoran, and Chihuahuan Desert and montane sky island regions of the southwestern United States and northern Mexico. Desert LCC science depends on access to transboundary base datasets. Given the importance of vegetation such as grasslands and riparian vegetation in conservation science, a bi-national, landscape-scale vegetation data layer with classes relevant to Desert LCC research is crucial. One objective of this project is to investigate appropriate methodologies and landscape scales to create a Desert LCC binational land cover...
In response to the rapid and dramatic hydroecological deterioration of the Rio Grande through Big Bend, the Big Bend Conservation Cooperative (BBCC), a multi-disciplinary group of natural resource agencies, research institutions, and conservation organizations have been organizing and implementing a wide range of river rehabilitation, scientific research activities and climate change initiatives. More recently, the Basin and Bay Expert Science Team, part of an environmental flows initiative by the state of Texas, is using best available science to recommend environmental flow regimes for the major rivers of Texas. Limited understating of the sediment dynamics of the Rio Grande and riparian vegetation change hinders...
