Animals in Delaware

Delaware is the second-smallest state in the US, with most of its land area on a coastal plain. It is the state with the lowest mean elevation in the country, not above 60 feet from sea level. Naturally, the Atlantic Ocean heavily influences Delaware’s climate and the habitat of the native wildlife. Its northern regions are covered in temperate broadleaf and mixed forests, while the southern parts have coastal forests.

Though the state has seen a lot of habitat loss due to deforestation and agricultural development, it is still home to numerous small and large animals – terrestrial, avian, and aquatic. And despite the small size, there are national parks and protected areas like the Chesapeake Bay Watershed and the Delaware Water Gap where you can experience nature and wildlife.
