University of Arizona will conduct an ecosystem conservation assessment for the lower San Pedro (LSP) watershed. The assessment will provide a science-based strategic design for prioritizing where conservation efforts are most needed for high-value biodiversity conservation at the landscape-level and offer insights on conservation actions practical for implementation. The assessment will include an evaluation of high-value biodiversity, hydro-ecological processes, protected areas, landscape connectivity, and climate change adaptation. The study will suggest approaches for developing a new conservation framework for watershed conservation planning.

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.

ABSTRACT: The Lower Colorado River and Rio Grande Basins are home to many riparian vertebrate species with different degrees of rarity. In our study, we focused on two species of birds and two species of gartersnakes that are associated with riparian areas: the Yellow-breasted Chat (Icteria virens), the Yellow Warbler (Setophaga petechia), the Northern Mexican Gartersnake (Thamnophis eques megalops) and the Narrow-headed Gartersnake (T. rufipunctatus). While the extent of distributions of these species is relatively large, they are often patchily distributed in populations that are small; in addition, both gartersnake species are listed as threatened under the Endangered Species Act. Aside from detrimental effects...

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...

Executive Summary: Our project combined field surveys of fish communities and habitat characteristics with estimates of population genetic structure to identify and evaluate critical factors influencing fish communities in the Gila River basin of New Mexico. Fish communities were structured along a strong habitat gradient associated with stream size, with distinct differences in the distribution of native and nonnative fishes. Nonnative warm-water species generally occurred in mainstem habitats, whereas coldwater nonnative salmonids occurred in high elevation tributaries. Habitat affinities of native species varied, with some occurring in mainstem habitats and others in tributaries. Several native species, such...

Final Report WaterSMART Agreement No. R13AP80033Introduction: Sky Island Alliance is a non‐governmental organization 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.Springs are keystone ecosystems in the Sky Island Region, exert disproportionate influence on surrounding landscapes, and are known to be biodiversity hotspots. Although they are abundant in this arid region, they are poorly documented and little studied. Changing...

Rocky Mountain Research Station scientists initiated a study in the 1990s on avian distribution and habitat associations within the Sky Islands. By re-measuring vegetation and bird populations following wildfires and applying climate change models, they will assess the singular and synergistic effects of climate change and wildfire and provide strategies for managing resilient forests and conserving the avian community structure. They will also continue and expand citizen science efforts to develop a long term avian monitoring plan, as well as simulation studies to provide optimal monitoring designs for avian species to detect changes from large-scale stressors.
