Our proposal addresses Funding Category Ill by evaluating natural resource management practices and adaptation opportunities. More specifically, our project addresses Science Need #6 to improve monitoring and inventory of watersheds and ecosystems (including invasive species). Our proposed study will occur within the Southern Rockies Landscape Conservation Cooperative (LCC) (upper Virgin River, UT) and the Desert LCC (lower Virgin River, AZ and NVL and therefore will be submitting to both cooperatives. Invasive saltcedar (Tamarix spp.) is the third most abundant tree in Southwestern riparian systems (Friedman et al. 2005). Resource managers must often balance the management goals of protecting wildlife species and...

The importance of riparian ecosystems in semiarid and arid regions has generated interest in understanding processes that drive the distribution and abundance of dominant riparian plants. Changes in streamflow patterns downstream of dams have profoundly affected riparian vegetation composition and structure. For example, in the southwestern United States, flow regulation has contributed to the replacement of many riparian forests historically dominated by the native Populus fremontii (Fremont Cottonwood) and Salix gooddingii (Goodding’s Willow) by the exotic species Tamarix spp. (Salt Cedar). The proposed project will help guide reservoir release decision making to enhance downstream recruitment of native cottonwood...

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...

A strong data foundation is needed to inform science-based decisions for fisheries management at a watershed level. In preparation for a shift towards comprehensive watershed-scale planning, Arizona Game and Fish Department (AGFD) is developing a fisheries data management system with an initial focus on compiling and formatting several hundred thousand fish survey and stocking records. Fish data will be integrated within a Geographic Information System (GIS) by georeferencing observations to an existing national spatial framework (National Hydrography Dataset), which will allow for broader transferability to watersheds shared with neighboring states, creating a seamless layer not limited by state boundaries. In...

The Grassland, Shrubland, Desert Program of the U.S. Forest Service, Rocky Mountain Research Station intends to evaluate the interactive effects of fire and climate change on the presence and long-term persistence of native and non-native species within Rio Grande riparian and wetland habitats of the Desert and Southern Rockies LCCs. Decision support tools and maps will be produced that will help resource managers identify conditions and locations where biodiversity will be most affected by future changes and identify needs with respect to species conservation and invasive species management.This project was co-funded by multiple Landscape Conservation Cooperatives: Desert LCC and the Southern Rockies LCC.

Changing climate conditions have been identified as a major threat to the sustainability and availability of water resources in the Southwestern U.S. Long-term decreases in precipitation can lead to reductions in regional groundwater levels and loss of groundwater storage in aquifers for some communities. Reduced precipitation can also lead to lower water levels in streams and losses in the vegetation that grows alongside riverbanks. The goal of this project was to identify how hydrologic systems in the Southwest might respond to changes in climate and the degree to which this response is dependent on the characteristics of the hydrologic system. To do this, researchers developed a tool that simulates how quickly...

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...

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...

Despite the lack of surface flows, the Colorado River riparian corridor in Mexico has proven to be ecologically resilient. Floods in the 1980s and 90s in the region brought back large swaths of native riparian habitat, which still persist today in some areas along the river. Because the historic floodplain is extremely important for agricultural production and therefore the local economy, habitat maintenance must be integrated with continued utilization of lands and water for this purpose.The riparian, marsh, and open-water areas found in Reach 4 provide critical habitat for both migratory and resident riparian bird species. Due to its ecological importance, the riparian corridor and Reach 4 in particular have been...
