Important Bird Areas


Important Bird Areas

Habitat loss is one of the most significant threats to not only bird populations, but all wildlife populations. Because no species can survive in isolation, the protection of significant areas of wildlife habitat is critical to any conservation movement. Important Bird Areas (IBAs) are sites that are recognized as being globally important for bird populations.

There are nearly 10,000 IBAs all over the world, with those in the United States being administered by the National Audubon Society. The first statewide IBA program was formed in Pennsylvania in 1996 and there are now over 80 IBAs recognized in Pennsylvania.

The best way to appreciate the importance of an IBA is to visit one yourself. The following is a list of nearby IBAs of southeastern Pennsylvania. Click on the location to learn more about each IBA.
