These heatmaps show a top 3 stressor or service, as ranked by participants, and the concentration of participants who reported as working in each municipality or county who also voted for that stressor or service across the landscape. This map shows the percentage of participants from each county and municipality who ranked Domestic Development as a top 3 ecosystem stressor in the Montane Habitat Fragmentation and Loss category in their region. 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...

Prymnesium parvum (golden alga, GA) is a toxigenic harmful alga native to marine ecosystems that has also affected brackish inland waters. The first toxic bloom of GA in the western hemisphere occurred in the Pecos River, one of the saltiest rivers in North America. Environmental factors (water quality) associated with GA occurrence in this basin, however, have not been examined. Water quality and GA presence and abundance were determined at eight sites in the Pecos River basin with or without prior history of toxic blooms. Sampling was conducted monthly from January 2012 to July 2013. Specific conductance (salinity) varied spatiotemporally between 4408 and 73,786 mS/cm. Results of graphical, principal component...

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...

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...

These heatmaps show a top 3 ecosystem service that could benefit most from collaborative conservation, as ranked by participants, and the concentration of participants who reported as working in each municipality or county who also voted for that service 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 services that participants chose. Counties with a small number of participants were not adjusted for small sample size. These results were shared via...

The Nature Conservancy has been a leader in spatial conservation planning for many years. The primary planning tool used by the Conservancy for landscape-scale conservation planning over the past decade has been Ecoregional Assessments. Our United States Ecoregional Assessments identify priority areas for conservation within the United States. This includes data from 67 Ecoregional Assessments, which identified over 9,000 conservation priority areas. Importantly, this dataset contains the conservation targets that we hope to conserve within these priority areas. Conservation targets include both species and habitat types (e.g. plant communities; ecosystems). Our dataset includes 8,507 unique species and 6,633 habitat...

This data layer was developed for use by regional conservation organizations and partners located in or adjacent to the Sky Islands region of the Southwest and to fill a key data gap, namely detailed, consistent, and project-relevant spatial datasets on land cover. These data emerged, in part, from a stakeholder-based process that involved the participation of multiple organizations, including Conservation Science Partners, Northern Arizona University, The Nature Conservancy, USGS, USFWS, Arizona Game and Fish Department, Borderlands Restoration, Sky Islands Alliance, Arizona-Sonora Desert Museum, and Universidad de Hermosillo. Development of these data was generously supported by Wilburforce Foundation. We developed...

The Environmental Conservation Online System (ECOS) is a gateway web site that provides access to data systems in the U.S. Fish and Wildlife Service (Service) and other government data sources. This central point of access assists Service personnel in managing data and information, and it provides public access to information from numerous Service databases. ECOS serves a variety of reports related to FWS Threatened and Endangered Species. A selection of our most popular reports is listed below. See the Species Reports for the complete list.

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.

The Sonoran Joint Venture Bird Conservation Plan (Plan) provides the biological foundation for the activities of the Sonoran Joint Venture (SJV). The Plan summarizes the status of avian species, prioritizes these species, provides habitat discussions and conservation recommendations, and lists Focus Areas for conservation action. This Plan will be a blueprint for regional bird conservation. It will guide the SJV staff, Board, and committees in their actions and inform SJV partners of beneficial activities. Finally and most importantly, this Plan demonstrates and emphasizes the need for conservation action and for the resources to achieve the SJV’s biological objectives. There are approximately 740 species documented...

About VAs: Although there are different definitions of vulnerability assessment, we adopted the definition provided by IPCC (2007) that pertains to climate change and suggests an understanding of vulnerability of a particular target, asset, or resource can be can be achieved through the assessment of exposure (magnitude and rate of climate change a resource is likely to experience), sensitivity (characteristics of a particular resource that mediate tolerance to climate change), and adaptive capacity (the inherent ability of the resource to moderate the impacts of climate change; IPCC 2007). This is also the most commonly used definition by the natural resources community (e.g., Glick et al. 2011). However, we...
