Understanding the physiological impacts of climate change on arid lands species is a critical step towards ensuring the resilience and persistence of such species under changing temperature and moisture regimes. Varying degrees of vulnerability among different species will largely determine their future distributions in the face of climate change. Studies have indicated that Northern Mexico and the Southwestern United States are likely to become climate change hotspots, experiencing significantly drier and warmer average conditions by the end of the 21st century. However, relatively few studies have examined specifically the physiological effects of climate change on species inhabiting this region. This manuscript...

There is a need to understand how alteration of physical processes on the Rio Grande River have impacted aquatic biota and their habitats, and a need to predict potential future effects of climate change on biotic resources in order to prescribe research and management activities that will enhance conservation of aquatic species. We propose a project with the goal of developing monitoring recommendations and identifying research needs for aquatic ecological resources in the Big Bend region of the Rio Grande. This goal will be targeted by synthesizing and analyzing available data and literature for aquatic species in the project region. In particular, we will work to develop time series of abundance and population...

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...

There are few resources that provide managers cross-scale information for planning climate adaptation strategies for species and taxa at risk. Appropriate allocation of resources requires an understanding of mechanisms influencing a species’ risk to global change. Dr. Griffis-Kyle will produce a manuscript for peer-reviewed publication and create content for web pages that can be included on the Desert LCC website that provide modules on amphibian climate adaptation strategies. This work is associated with addressing Desert LCC Critical Management Question 4: Physiological Stress of Climate Change and follows a webinar that Dr. Griffis-Kyle presented for the Desert LCC’s CMQ 4 team, titled “Climate and Desert Amphibian...

The Bird Conservancy of the Rockies will use, combine and optimize an array of remote sensing techniques to identify the most efficient process that characterizes grasslands and level of shrub component in those grasslands. The project will classify a pilot area, the Janos Grassland Priority Conservation Area, which contains the majority of the Janos Biosphere Reserve, using a variety of remote sensing approaches. In the process they will identify the best techniques for decomposing grass-shrub intermix at low densities and identify the best approaches for large scale application of remote sensing to classify the desert grasslands and shrublands.

Our approach will include sampling a wide range of habitats and environmental conditions throughout the middle and lower Pecos River basin, across an 18 month time-span to account for seasonal and phenological events. We will utilize a suite of univariate and multivariate statistical techniques to relate occurrence and density of golden alga to environmental factors and other co-occurring organisms. The proposed research will benefit managers of the Pecos River, of its associated reservoirs and unique habitats (sinkholes on the Bottomless Lakes State Park and Bitter Lakes National Wildlife Refuge), and of its resident aquatic biota by identifying specific water quality attributes that promote golden alga bloom development...
The Desert LCC will provide the 50% of the Federal component of funds, and the work designed will support the science objectives for the Desert LCC and its partners as well as provide needed improvements to the National Hydrography Dataset (NHD) in the Lower Colorado River Region, and beyond. Basic improvement of the NHD at the 1:24,000 scale will provide an important framework basis for the development of hydrologic models required to address effects of climate change. An accurate surface water map will support the following specific DLCC objectives and needs: Hydrologic and biological modeling Accurate determination of perennial and intermittent classification Impacts on flow due to storms (particularly in the...

Topock Marsh is a large wetland adjacent to the Colorado River and main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, 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 2010-2011. Co-applicants Daniels and Haegele of FORT monitored Topock Marsh during the drawdown and immediately after, thus obtained information on immediate effects. However, stress from the drawdown may have a delayed effect on aquatic resources; additionally, significant changes to the infrastructure...

University of California Riverside’s Center for Conservation Biology will create a sustainable resource monitoring framework that will provide empirical data identifying if and how climate change is changing the composition and vitality of Joshua Tree National Park. These data will then help focus the Park’s resource management programs to help ensure the Park’s rich biodiversity can be sustained to the extent possible. A broader goal is to have this framework adopted across the surrounding public lands to then integrate data from multiple sites and land management philosophies to create an unambiguous picture of the impacts of climate change across the desert region.
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...

Assessing the vulnerability of species or ecosystems to climate change and formulating appropriate management responses requires predictions of the exposure and sensitivity of the species or ecosystems to projected changes. This collaborative effort by the Sonoran Joint Venture, Desert Landscape Conservation Cooperative, and Point Reyes Bird Observatory will develop a foundation for monitoring environmental change in the desert southwest by identifying where and what to monitor in order to evaluate climate-change impacts.Climate change will not have the same effects in all locations of the southwest. Some areas will change quickly (hotspots) and others will change slowly (refugia). Identifying both types of areas...

Grasslands are among the most threatened ecosystems on the planet (Hoekstra et al 2004). Recently, the bird conservation and grasslands communities have united around a forward looking approach to conservation planning. To accomplish this the following information is needed:1) The location, quantity, and quality of desert grasslands,2) the regional risks associated with loss or degradation of grasslands,3) the vulnerability of those grasslands and the species that depend on them to environmental and climate stressors,4) where and what types of programs or partnerships exist on the landscape to address system stressors and implement further conservation programs, and5) what capacity for conservation do these entities...

Freshwater systems are critically imperiled and continue to be threatened by human encroachment and water development. The upper Gila River in New Mexico is one of the last unobstructed rivers in the Colorado River basin with a mostly intact native fish fauna, including two federally listed and one state-listed fish species. Kansas State University will develop methodologies or decision support tools to assess or evaluate current or existing resource management practices to learn and adapt to the effects of climate change on fish species. The researchers will investigate how the connectivity of the Gila River habitat impacts the fish population with respect to the behavior of native and non-native species.

Riparian ecosystems are among the most productive and diverse ecosystems in desert biomes. In the Sonoran, Chihuahuan, and Mojave deserts of the United States and Mexico, riparian ecosystems support regional biodiversity and provide many ecosystem services to human communities. Due to the dynamic nature of these ecosystems and their abundance of resources, riparian areas have been modified in various ways and to a large extent through human endeavor to manage water and accommodate various land uses, particularly in lowland floodplains and stream channels. Modifications often interfere with multiple and complex ecological processes, resulting in the loss of native riparian vegetation and increasing vulnerability...
