These heatmaps show a top 3 invasive and problematic plant stressor for montane areas in the Chihuahuan Desert, as ranked by participants, and the concentration of participants who reported as working in each municipality or county who also voted for that stressor across the landscape. Symbology represents the percentage of participants with 0% = dark green, 0.0001 % - 24.99% = light green, 25% - 49.99% = yellow, 50% - 74.99% = orange, 75% - 100% = red. All counties and municipalities identified by participants as areas where they work were given a tally for each of the top 3 stressors that participants chose. Counties with a small number of participants were not adjusted for small sample size. These results were...

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 four primary objectives of this project were to: (1) compile a dataset of fish occurrence records for the entirety of the Rio Grande drainage in the US and Mexico; (2) improve that dataset by reformatting dates, synonymizing species names to a modern taxonomy, georeferencing localities, and flagging geographic outliers; (3) for those species with sufficient data for modeling, create species distribution models (SDMs); (4) use the environmental conditions determined via those models to project the species distributions into the future under two climate scenarios. To accomplish those objectives, we compiled 495,101 fish occurrence records mined from 122 original sources into a single database. We then, on the...

Native Nations face unique challenges related to climate change, many of which are detailed in recent reports as part of the U.S. National Climate Assessment (Bennett et al. 2014; Hiza Redsteer et al. 2013). Native Americans have a deep connection to the natural environment within which their livelihoods, cultural identity, and spiritual practices are rooted. Changes to hydrologic regimes, landscapes, and ecosystems, in combination with socio-economic and political factors, amplify tribal vulnerabilities to climate change. In the Southwest, tribes are already experiencing a range of impacts that are at least partially related to climate change. They include serious water supply and water quality issues in the...

Abstract: Topock Marsh is a large wetland adjacent to the Colorado River and the main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, the U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010–11. U.S. Geological Survey Fort Collins Science Center (FORT) scientists collected an assemblage of biotic, abiotic, and hydrologic data from Topock Marsh during the drawdown and immediately after, thus obtaining valuable information needed by FWS. Building upon that work,...

Executive Summary: We provide an analysis of Sonoran Desert water network connectivity to inform managers of current conditions for target wildlife and how the connectivity will change as the landscape becomes more water limited.Climate change is expected to lead to fragmentation of the network, increasing coalescence distance by 8% and reducing the persistence and overall number of waters on the landscape. Identification of key water sites, ranked by network connectivity metrics, are presented in Appendix B. Wetland number under our scenario of water limitation will decline by 43% reducing network resilience.Anurans and Caudates, although varying in ability to disperse, generally experienced reduced connectivity...

ELCOM and CAEDYM are three-dimensional finite-difference codes; they were used to simulate three-dimensional transport and the interactions of flow, physics, biology, and chemistry in the reservoir. The study indicated that the hydrodynamic flow patterns within Boulder Basin are mainly driven by the Colorado River inflow, the Hoover Dam outflow, and meteorological parameters. However, the water quality of Boulder Basin is also affected by the load of nutrients from the Las Vegas Wash, which carries the treated wastewater effluents from municipal wastewater treatment plants, surface runoff, and groundwater discharges into the basin.The goal of this proposed project is to assess the potential for changes in water...

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...

Pilot areas A and B produced in site selection process and analysis was centered on input criteria from DLCC stakeholders for the best representation of the desert land cover and priority habitats. The input from the DLCC stakeholders was compiled into a Weighted Matrix. The Weighted Matrix was ranked (with values assigned between 1 and 10) based on the level of importance held by the criteria and based on the datasets used for analysis.

The climate data were collected between 1988 and 1995 and include portions of 25 volumes of fan-fold line-printer computer printouts, with 10 columns of variables per page. The legacy weather data was entered into Excel spreadsheets and delivered to the Arizona State Climate Office, Navajo Nation, and the Desert and Southern Rockies LCCs. This project was completed by the USGS Arizona Water Science Center in cooperation with the Navajo Nation.
In September 2013 the Springs Stewardship Institute received funding from the BOR to map springs and springs-dependent species in the DLCC. Since then we have configured our server, migrated our geodatabase to an ArcSDE, and published several WMS and WFS to our domain at https://arcgis.springsdata.org/arcgis/rest/services . This includes a WMS of springs in the DLCC that we have also made available through ArcGIS Online at http://bit.ly/1k6zo7p . We have also migrated our non-spatial survey data to an online application at http://springsdata.org/index.php . This is a user-friendly interface for a MySQL database that includes georeferencing, geomorphology, flow, flora, fauna, water quality, and condition assessment...

Climate change predictions include warming and drying trends, which are expected to be particularly pronounced in the southwestern United States. In this region, grassland dynamics are tightly linked to available moisture, yet it has proven difficult to resolve what aspects of climate drive vegetation change.Here, we combine climate and soil properties with a mechanistic soil water model to explain temporal fluctuations in perennial grass cover, quantify where and the degree to which incorporating soil water dynamics enhances our ability to understand temporal patterns, and explore the potential consequences of climate change by assessing future trajectories of important climate and soil water variables.Our analyses...
Riparian ecosystems are vital components of aridlands within the southwestern United States. Historically, surface flows influenced population dynamics of native riparian trees. Many southwestern streams has been altered by regulation, however, and will be further affected by greenhouse warming. Our analysis of stream gage data revealed that decreases in volume of annual discharge and mean peak discharge and a shift to earlier peak discharge will occur in the Southern Rockies region of Colorado, New Mexico, and Utah. These changes will likely decrease rates of reproduction and survival of cottonwood (Populus fremontii and Populus deltoides ssp. wislizenii), Goodding’s willow (Salix gooddingii), and boxelder (Acer...

Executive summary: The avifauna within the Sky Islands of southeastern Arizona includes species found nowhere else in the U.S. Thus, birdwatchers from across the globe visit the region, providing a vibrant state and local ecotourism industry. RMRS scientists initiated a study in the 1990s on avian distribution and habitat associations within the Sky Islands. Since then, the region has been under increased stress from ongoing droughts and wildfires, likely associated with climate change. By re-measuring vegetation and bird populations in 2014 following wildfires and applying climate change models, we will assess the singular and synergistic effects of climate change and wildfire and provide strategies for managing...
