The Pennsylvania Natural Heritage Program has amassed a tremendous amount of biodiversity data over its existence. Putting that information to work for conservation is primary to our mission and creating tools that allow people to use it has become a critical part of our program. Our interactive maps, reports, and other conservation tools serve different functions but can work together to provide maximum information about the potential biodiversity of a given area.
