Make a Difference in Maryland and DC
From Western Maryland's Central Appalachian forests to our nation's capital and beyond to the Chesapeake Bay, we're working to deliver large-scale, science-based conservation solutions for both people and nature.
Our Priorities
Learn more about our conservation efforts across the region.
Appalachian Forests
Western Maryland holds a critical slice of the Appalachian range. With large scale conservation lands to the south in West Virginia and to the north in Pennsylvania, keeping the forests of western Maryland healthy and connected is a top priority.
Chesapeake Bay
The Chesapeake Bay is the largest estuary in North America and one of its most vital ecosystems. Although the brackish waters of the Bay only touch Maryland and Virginia, its 64,000-square-mile watershed spans six states and the District of Columbia connects a diverse landscape of farms, forests, cities and wetlands.
Policy and Government Relations
The Maryland/DC chapter's Government Relations team works at the state level to advance forward-thinking policies on conservation and climate issues such as climate change mitigation, climate resilience and investments in nature.
