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...

Introduction: Tamarisk (Tamarix spp., also saltcedar) is a non-native tree introduced to the United States during the 19th century as an ornamental species and solution to erosion in the American West (Robinson 1965). Tamarisk can form dense monotypic stands, which have been linked to a decline in richness and diversity of native plants (Engel-Wilson & Ohmart 1978; Lovich et al. 1994) and wildlife (Anderson et al. 1977; Durst et al. 2008) in riparian areas. As a result, natural resource managers have invested millions of dollars to control tamarisk (Shafroth & Briggs 2008). Few studies have conducted community-level analyses to document the impact of one of these methods, the introduction of a native enemy or predator,...

Executive Summary: Portions of broad-scale ecoregions of the Great Plains, and Southern Semiarid Highlands were generally projected as mostly suitable for large fires of low severity within 31 years. Under a 2070 future climate scenario of high CO2 emission (HadGEM2-ES RCP8.5) a significant increase in suitability for large low severity wildfires was seen in Wyoming and Montana, which was accompanied by a decrease in suitability for the Madrean Archipelago and portions of central and west Texas. Broad scale niche model for the Southwestern Willow Flycatcher under current climate was centered within the known breeding range mostly along riparian areas. Under a 2070 future climate scenario of high CO2 emission (HadGEM2-ES...

Pectis imberbis A. Gray is an endemic plant species native to southern Arizona with fewer than 400 known individuals in existence. A total of 6 putative populations, each consisting of between ca. 10 and 180 individuals, occur at elevations of 1100-1700 m in a variety of habitats, including oak woodlands, desert grasslands, oak savannas, and disturbed areas in Arizona (road cuts, arroyos) (USFWS 2012). In the past, populations were also identified in Mexico (Keil 1978, USFWS 2012); however, Mexican populations have not been relocated in recent years (Keil 1982, Falk and Warren 1994, Sanchez-Escalante 2018a, 2018b). Resurveys of known P. imberbis sites suggest significant decline in abundance over the last two decades...
FY2016This project will evaluate the effects of vegetation treatments on population connectivity, genetic diversity and gene flow of wildlife species across the full extent of the Great Basin LCC. The recently approved BLM and Forest Service Land Use Plan Amendments will implement millions of acres of treatments in support of greater sage-grouse conservation. It is essential to evaluate the potential benefits and risks of these treatments on the connectivity and fragmentation of the landscape for multiple non-target species. We will use a dynamic landscape model to simulate fire and treatments, allowing each to vary by type (e.g., juniper removal, prescribed fire), extent, and influence on vegetation and fuels....

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...

Article Abstract: Although riparian and aquatic ecosystems make up a small fraction of the area in arid and semi-arid lands, they are critical for the survival of desert life. There are, however, few compendia of efforts to define the quantity of water needed to maintain these ecosystems and understand the risks and stressors to them. Through our analysis we found that 62% of the rivers examined in the deserts of the U.S. and Mexico have had just one study over the past four decades and 67% of studies used qualitative methods. Furthermore, only one-third of the 312 species catalogued in our work have been studied more than once and only 5% have been considered five or more times. The most common risks or stressors...

The Washington Connected Landscapes Project will provide a framework to address the interacting impacts of habitat fragmentation and climate change on ecological systems and wildlife species within the Great Northern Landscape Conservation Cooperative (GNLCC) boundary.Managing for well-connected landscapes is a key strategy to enhance resilience and ensure the long-term viability of plant and animal populations. However, conservation planning efforts have rarely included connectivity for ecological processes such as dispersal, migration, and gene flow. Connectivity conservation is particularly important in the face of climate change, because many species will require highly permeable, well-connected landscapes not...

The goals of this study are to: (1) generate a genetic toolset (80-90 microsatellite loci per species) for long term genetic monitoring of both wild and captive populations of each threatened gartersnake species (THEQ & THRU) that inhabit Arizona and New Mexico; (2) conduct field surveys at Saliz Creek to assess the genetic, demographic, and life history effects of a 2012 wild translocation event for THRU to better assess the strategies of genetic management and success of translocations; (3) conduct targeted surveys for both species at key sites to collect additional samples from geographic gaps and increase sample sizes at previously sampled sites to further evaluate connectivity and genetic diversity of these...
Sky Island Alliance (SIA) is a non-governmental organizational that works to protect and restore the rich natural heritage of native species and habitats in the Sky Island Region. We work with volunteers, scientists, land-owners, public officials, and government agencies to establish protected areas, restore healthy landscapes, and promote public appreciation of the region’s unique biological diversity. Because of our long-standing collaborative relationships with land managers and our large corps of skilled volunteers, we were in a unique position to spearhead this project.SIA initiated this springs inventory, assessment and management planning project to develop baseline information on springs in the Sky Island...

Aquatic conservation in arid ecosystems is a pressing concern for the public and land managers in the Southwest. This study focuses on aquatic conservation issues in 2 sites – 1 international site, Cuatro Ciéneags, México and 1 Arizona site, Fossil Creek which was the focus of a collaborative, multi-faceted stream restoration project. In Cuatro Ciénegas, we conducted an experiment manipulating fish access to stromatolites. We manipulated 2 fish species that occur with stromatolites, the polymorphic Herichthys minckleyi, and the pupfish Cyprinidon bifasciatus. We used a trophic cascade index as an indicator of cascade strength, and only molariform morphs were responsible for a trophic cascade, reducing snail densities...

Our 2010 statewide connectivity analysis identified broad-scale priority areas for connectivity conservation. More detailed, finer-scale analyses will give land managers the information they need to begin prioritizing and implementing conservation actions. The Columbia Plateau (Appendix A, Fig. 1) was selected for the first ecoregional-scale analysis for two reasons. First, several climate models suggest that the Columbia Plateau Ecoregion in Washington is likely to be a stronghold of shrubsteppe ecosystems under climate change. Second, despite the high level of habitat loss and fragmentation in the ecoregion, our statewide analysis identified previously undocumented patterns and opportunities for multiple-species...

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...

Resource managers must often balance the management goals of protecting wildlife species and habitats with control of non-native and invasive plants. This project will determine if the introduction of the biocontrol agent (tamarisk leaf beetle, Diorhabda spp.) as an insect consumer and defoliator of saltcedar influences wildlife populations and communities via alterations to food resources and/or habitat. By taking advantage of an unprecedented natural experiment and two years of pre-biocontrol monitoring, the researchers will track changes in amphibian and reptile (herpetofauna), and avian communities as biocontrol enters a system dominated by a non-native plant species. The investigators predict that the introduction...

The University of California, Davis in partnership with the Navajo Nation is partnering with the Southern Rockies LCC to provide estimates of habitat connectivity for focal species on the Navajo Nation and adjacent lands that the tribe wishes to incorporate into planning and implementation of adaptive management. The project will derive habitat variables as inputs for connectivity models, and model outputs likely will include habitat quality and conductance. Species-specific models will be mathematically integrated to permit probabilistic statements about simultaneous connectivity for two or more species. The spatial data developed on wildlife distributions and habitat to model connectivity and, ultimately, viability...

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...
