WGA Crucial Habitat Assessment ToolFeatured Date: December 23, 2013

WGA Crucial Habitat Assessment Tool

With the launch of this Western Governors' Crucial Habitat Assessment Tool (CHAT), the Western Governors' Association and its Wildlife Council aim to bring greater certainty and predictability to planning efforts by establishing a common starting point for discussing the intersection of development and wildlife. While not intended for project-level approval, CHAT is designed to reduce conflicts and surprises while ensuring wildlife values are better incorporated into land use decision-making, as well as large-scale conservation projects.

The History of CHAT

With the adoption of its Wildlife Corridors Initiative Report in 2008, the Western Governors created the Western Governors' Wildlife Council and tasked its members with developing policies and tools to identify and conserve crucial wildlife habitat and corridors across the region.

The Wildlife Council first approached the Governors' directive by launching regional pilot projects in 2010 with support from a grant from the Department of Energy. The year-long pilot projects allowed the Wildlife Council to test the framework outlined in their White Paper, helping to refine their vision.

In August 2011, the Wildlife Council established a plan to develop a West-wide tool with the goal of launching a public and regionally compatible crucial habitat GIS tool by 2013. All the while, the Wildlife Council has continued to support the development of state-specific CHATs in individual states.

Now guided by WGA policy resolution 13-04 and focused on implementing the CHAT model, the Wildlife Council is working to make information on important fish and wildlife habitat compatible across the West and available to the public for use in informing land use decisions.

CHATs in Individual States

Arizona, California, Kansas, Montana, Washington and Wyoming have already developed state-specific information on priority species and habitat. In addition, the Southern Great Plains CHAT provides information specific to the lesser-prairie chicken, a species with habitat ranging across five states. Other states are continuing to develop individual systems to provide additional state-specific information.

National Wetlands InventoryFeatured Date: November 12, 2013

National Wetlands Inventory

U.S. Fish and Wildlife Service - The development of the new Wetlands Mapper stems from the U.S. Fish and Wildlife Service's (Service) need to expand and improve the availability of digital wetlands data. The Service's strategic plan for digital wetland data is focused on the development, revision, and dissemination of wetlands data and information to Service resource managers and the public. The present goal of the Service is to provide the citizens of the United States and its Trust Territories with current geospatially referenced information on the status, extent, characteristics and functions of wetlands, riparian, deepwater and related aquatic habitats in priority areas to promote the understanding and conservation of these resources.

The revision of Wetlands Mapper is in direct response to the need to integrate digital map data with other resource information to produce timely and relevant management and decision support tools.

This new version of the Wetlands Mapper is designed to promote greater awareness of wetlands map data applications and to deliver easy-to-use, maplike views of America's wetland resources in a digital format. It has been developed in collaboration with the U.S. Geological Survey (USGS), Water Resource Division. This Federal partnership has yielded tremendous benefits in ongoing efforts to configure, improve and distribute the wetlands map information using newer technologies in computerized mapping and web-serving capabilities.

Gap Analysis Program (GAP) Species ViewerFeatured Date: November 05, 2013

Gap Analysis Program (GAP) Species Viewer

The Gap Analysis Program (GAP) Species Viewer displays data on vertebrate species ranges and distribution models for the continental U.S. as well as Alaska, Hawaii, Puerto Rico, and U.S. Virgin Islands. More specifically, species distribution models based on deductive modeling of habitat associations are displayed across entire species ranges for over 2000 species. Our goal is to build species range maps and distribution models with the best available data for assessing conservation status, conservation planning, and research (e.g., climate change impacts). Ranges are represented by 12-digit HUCs with attributes of occurrence/presence, origin, reproductive use, and seasonal use. Distribution models, created at 30 meter resolution, are based on habitat associations from published literature and core data sets, such as elevation and land cover. To date, we have a portion of our total species available through the GAP Species Viewer. As more species ranges and distribution models are completed, we will continually update our data on the GAP Species Viewer. Please check back for updates.
