Maps of bird species can help protect living things

The researchers calculated that the number of bird species found in areas adjacent to the US Blue, there are fewer birds than in the green or yellow areas. Found: Kathleen Carroll and Anna Pidgeon

New, more accurate, and more secure maps of bird life can help prevent predators or threats.

Researchers at the University of Wisconsin – Madison has developed maps in a highly effective way to help administrators put their practices where they can help the birds – in counties or forests, rather than in all states or districts.

The maps apply to the U.S. and predict the diversity of birds living in a given area, depending on factors such as nest on land or disaster. Those predictions are based on both bird’s and natural characteristics about bird levels, such as the height of forest cover or the temperature of an area.

“With these maps, executives have tools they didn’t have before so they can have a broad view and insight into the level of detail needed for their design. work, ”said Anna Pidgeon, a professor of forestry and wildlife at UW – Madison who helped develop the maps.

Pidgeon worked with UW -Madison professor Volker Radeloff, postdoctoral researcher and lead author Kathleen Carroll and others to publish the research and final papers April 11 in the journal. Ecological applications. Maps for download to the public are available from the Dryad website.

The research was designed to address two important issues in management.

“All over the world we’re seeing the biggest losses. In North America, 3 billion birds have gone missing since 1970. This is close to all habitat species,” Carroll said. “And we’re seeing a difference between what scientists do to maintain it and how it translates to boots-on-the-ground navigation.”

Many resources previously available to administrators, such as various types of maps, have not been used or tested for accuracy.

To overcome those challenges, Carroll and his team wanted to develop maps that were based on data on bird life. They created maps by increasing birdwatching from scientific research to mile-by-mile predictions of habitat of different species. Those predictions are based on factors such as rainfall, forest cover levels and the amount of human influence on the environment, such as urban areas. Not farmers.

To improve the predictive power of their maps, scientists have gathered a variety of methods such as habitat, habitat, food, or care – such as those who eat fruits or vegetables. forest dwellers. These groups are called guilds. There are a lot of care decisions at the guild level, not at the genres level. Guilds can eliminate little knowledge about the most evil types.

The final maps cover 19 different guilds at resolutions of 0.5, 2.5 and 5 kilometers. While the best maps aren’t accurate, the 2.5-kilometer resolution maps provide a balance of accuracy and usefulness for real-life care needs, scientists say. With a 5-kilometer solution, the maps provide the most accurate and reliable to security personnel working in large areas.

“We find this to be appropriate for things like forest management plans for the U.S. Forest Service,” Carroll said. “They can pull up these maps for an interesting group, and they can get a very clear picture of the areas they want to limit human use.”

Maps can help private landowners decide where to first choose low -income resources to increase biodiversity protection.

Carroll is now working to extend the look to different types, rather than guilds created in multiple types. A higher level of detail can help special care managers improve their performance, especially those who intend to avoid a condition.
