Which types of ecosystems are prevalent in Pennsylvania?

The dominant ecosystems in Pennsylvania are characterized by a rich diversity that includes forests, wetlands, grasslands, and aquatic systems.

Forests are particularly important in Pennsylvania, covering a significant portion of the state and providing habitats for numerous species of wildlife. These forests consist mainly of deciduous trees, such as oak, maple, and hickory, which contribute to the state's ecological balance. Wetlands serve as critical areas for water filtration, flood control, and habitat for a variety of plant and animal species. Grasslands, though less common than forests, support different ecosystems and species that thrive in open areas. Additionally, Pennsylvania's aquatic systems, including rivers, lakes, and streams, are vital for sustenance and recreation, playing a crucial role in the state's overall health and biodiversity.

In contrast, deserts and tundras, mountain ranges and arctic zones, and urban environments do not represent the primary ecosystems found in Pennsylvania, as these options either describe climates or geographical features not typical of the region or narrow the focus solely to urban settings without consideration for the natural ecosystems that characterize the landscape.
