The U.S. Fish and Wildlife Service has a long tradition of scientific excellence and always uses the best-available science to inform its work to conserve fish, wildlife, plants, and their habitat for the benefit of the American public.
Created in 1903 by President Theodore Roosevelt, today's National Wildlife Refuge System protects habitats and wildlife across the country, from the Alaskan tundra to subtropical wetlands. Managed by the U.S. Fish and Wildlife Service, the Refuge System's 560-plus refuges cover more than 150 million acres and protect nearly 1,400 species of birds, mammals, reptiles, amphibians, and fish.
While national wildlife refuges were created to protect wildlife, they are for people too. Refuges are ideal places for people of all ages to explore and connect with the natural world. We invite you to learn more about and visit the national wildlife refuges and wetland management districts in Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming.
The Mountain-Prairie Region's Office of Ecological Services (ES) works to restore and protect healthy populations of fish, wildlife, and plants and the environments upon which they depend. Using the best available science, ES personnel work with Federal, State, Tribal, local, and non-profit stakeholders, as well as private land owners, to avoid, minimize, and mitigate threats to our Nation's natural resources.
Providing leadership in the conservation of migratory bird habitat through partnerships, grants, and outreach for present and future generations. The Migratory Bird Program is responsible for maintaining healthy migratory bird populations for the benefit of the American people.
The U.S. Fish & Wildlife Service Fish and Aquatic Conservation Program in the Mountain-Prairie Region helps conserve, protect, and enhance aquatic resources and provides economically valuable recreational fishing to anglers across the country. The program comprises 12 National Fish Hatcheries.
Law enforcement is essential to virtually every aspect of wildlife conservation. The Office of Law Enforcement contributes to Service efforts to manage ecosystems, save endangered species, conserve migratory birds, preserve wildlife habitat, restore fisheries, combat invasive species, and promote international wildlife conservation.
External Affairs staff in the Mountain-Prairie Region of the U.S. Fish and Wildlife Service provides support to the regional office and field stations to communicate and faciliate information about the Service's programs to the public, media, Congress, Tribes, partners, and other stakeholders in the 8-state region.
Delivering Digital Wetlands Data Using a
Web-Based Browser-Driven Mapper By Bill O. Wilen, Ph.D. and Deb Southworth
U.S. Fish and Wildlife Servic
The U.S. Fish and Wildlife Service's National Wetlands Inventory has made digital wetlands data for one million square miles of the surface of the conterminous United States viewable over the internet through the Wetlands Interactive Mapper. It is a web-based, browser-driven system that allows anyone with an internet connection to: 1) view digital wetlands data, 2) conduct basic processing (e.g., zoom, pan, identify, etc.), and 3) print custom maps and acreage reports on their desktop color printers. The map display includes a tool bar with processing operations, message box, map coordinate display, map scale display, legend, and help button. There is also a link to the Microsoft Terraserver, which allows the user to view an aerial photograph or a U.S. Geological Survey map for the area displayed. The mapper is available on the National Wetlands Inventory web site at http://wetlands.fws.gov. The U.S. Fish and Wildlife Service and the U.S. Geological Survey are agencies within the U.S. Department of the Interior.
Value of Wetlands
Wetlands are the cornerstones of many important and complex ecosystems that provide countless benefits for fish, wildlife, and people. They are living filters that help purify our nation's waters. Marshes, swamps, and bogs serve as water storage basins that help lower the magnitude and frequency of floods. Wetlands provide critical habitat for the survival of a major portion of the migratory and resident fish and wildlife of the nation. Many common and rare species use wetlands for food, water, cover, or reproduction.
Engaging the Public
The need for digital data that identifies potential environmental conflicts and tracks natural resource trends is growing rapidly. Maintaining wetlands and other natural resources is a quality of life issue. Livability starts with healthy ecosystems. Maintaining healthy ecosystems requires sound planning and management, as well as the support and understanding of the citizenry. With improved access to wetland information, they can better understand these systems and become involved in identifying and voicing enlightened opinions on community issues and policies involving these important habitats. By putting more information into the hands of the public, they can exercise their decision-making power to maintain or improve the livability of their communities.
Wetlands Interactive Mapper
Currently, the Internet connected public can view digital wetlands data, produce a custom map, and print the map along with an acreage summary on their desktop color printer. The mapper allows them to make wetland maps of their county, city, town, and, most importantly, their neighborhood. The mapper is part of the Service's Environmental Conservation Online System (ECOS), an ongoing project to make environmental data available on the web.
Making A Map
The mapper is initiated by typing in a county name, city name, zip code, or the name of a Fish and Wildlife Service National Wildlife Refuge. The map display includes wetlands, streams, and roads. The user can add railroads or refuge boundaries to the display. Spatial processing buttons allow the user to zoom in to an area of interest. As the user zooms in, more map detail is provided. The wetlands legend also changes to provide additional information concerning the different types of the wetlands. Zooming out results in doubling the spatial area of the map. The Identify tool allows the user to identify not only the classification of individual wetlands, but also the names of roads and streams. The results from the identification search appear in the expandable query and results frame below the map. This frame is entitled "Map Utilities." Most of the processing features work on a point and click basis. More advanced users can use the download icon to transfer spatial themes for use in geographic information systems.
Printing a Map and Acreage Report
Once the desired map is displayed on a screen, the map can be formatted for printing by clicking on that option in the Map Utilities frame below the map. When the link is made, a new window will open containing the desired map and legend. It can be printed by selecting File/Print from the menu. The map can be printed with either a portrait or landscape orientation. Wetland acreage summaries for the map can be generated by general type, class, subclass, or full attribute. This is accomplished by clicking on the desired level of detail below the title View Wetland Acreage Summaries. When the desired level of detail is selected, a new window will open. The acreage summary will appear in the window. The acreage report can also be printed.
Other Important Links
The Map Utilities frame has a link to the Microsoft Terraserver. It allows the user to view an aerial photograph or United States Geological Survey map of the area. The final link is to the National Wetlands Inventory's map status page. This provides a link to graphics of digital wetlands data and access to the Wetland Maps Database through a search form. This link is important because the wetland maps must be in a digital format to be viewable over the internet. Digital wetlands data (see figure) is available for one million square miles of the surface of the conterminous United States. Final maps for an additional million square mile area are awaiting to be digitized. Funding for the existing digital data has been provided by 52 agencies and organizations including Federal, State, and county agencies; Native American Tribes; and such private sector organizations as Ducks Unlimited.
The interactive mapper is the beginning of web-based tools to provide the general public with a better geographic view of the wetlands near the places where they live. It is becoming an effective way to provide the public with detailed environmental information about wetlands, important landscape features, and other conservation issues.
