Discover Pennsylvania’s Important Bird Areas
Great Marsh, Chester County
Pennsylvania’s IBAs include a great diversity of locations to
protect our great diversity of birds. They range from city parks
that are important migrant stopover habitat or contain a critical heron
colony to large wetlands or forest blocks that support populations of
many birds that need that habitat. These IBAs also vary greatly
in ownership and size. Recent studies have suggested that
Pennsylvania’s wetland birds are declining even faster than realized
previously. Due to its extensive forest cover, Pennsylvania is
critical to the conservation of several woodland songbirds such as Wood
Thrush and Scarlet Tanager. 
Visit the IBA website, including its conservation plans, maps, and,
even more important, visit the sites and watch birds there. Your
eBird data collected at these sites will help everyone better
understand how they support critical wildlife resources and will
contribute to our ability to protect and manage these sites for future
generations. It also will help us monitor changes in bird
populations at each site.
There currently are 85 designated IBAs in the state. Many
eBird hotspots are either a part of or an entire
IBA. To help facilitate community involvement, Audubon
Pennsylvania initiated the IBA Stewardship Adoption Program in 2001.
This program encourages and enables individuals, organizations or
institutions to “adopt” a specific IBA and partner directly with us to
monitor and protect that site.
Get involved by contacting Audubon Pennsylvania.
