Stretching along the Pacific Northwest from southeastern Alaska to northern California, from the Pacific coast to the Continental Divide, the 750,000-square-mile Cascadia Bioregion includes the world’s largest temperate rain forest zone. Its lands and waters are home to wolves, salmon, orcas and other iconic species deeply connected to the ways of life of many indigenous communities and to the cultural, ecological, and economic well-being of the entire Bioregion. The region is also known as a leader in advancing sustainability in the built environment. Habitat restoration and the protection of clean water are central to our work here.

Home to the largest group of freshwater lakes in the world, the Great Lakes Bioregion extends from the southern edge of the Niagara escarpment into eastern Wisconsin. With topography carved by glacial flows, the bioregion contains a broad diversity of upland and lowland habitat susceptible to drought and wet cycles. Driven by regional passion for its unique waterbodies, as well as legacy impacts of industry and agriculture that defined the region for centuries, a robust network of dedicated agencies and organizations is improving ecology and water quality in the bioregion. We are honored to partner with many of them.

The Hudson River Bioregion flows from highly urban areas to sweeping highland within glacial fjords, and features ecosystems ranging from mixed temperate forests to coastal plains and marshes. In highly urban areas where constraints associated with historical land manipulations exist, we apply innovative approaches to restore ecological function. In less developed areas of the bioregion, we pursue conservation and enhancement.

The Appalachian Mountains and the Cumberland Plateau meet in the Ohio River Bioregion, where the climatic transition from humid continental to subtropical areas contributes to the region’s rich ecological diversity. This Bioregion primarily focuses on impacts to the Ohio River and its tributaries, in a drainage area that spans 15 states, includes 16 ecoregions, and supports more than 160 species of fish. Nature-based solutions for communities in this Bioregion are nuanced to respond to a diversity of political, social, and ecological conditions.  

Sweeping from the barrier islands of the Carolinas to the eastern edge of the Mississippi Alluvial Plain, the Southeast Atlantic Bioregion encompasses a wide variety of ecosystems, including marsh habitats. Draining to either the Atlantic Ocean or the Gulf of Mexico, the watersheds of this region support a broad diversity of life… and human livelihoods. Its municipalities—which include many coastal communities—face challenges ranging from rapid urbanization, water pollution, and environmental injustice to sea level rise and increasingly frequent storm surges. Our nature-based solutions aim to enhance biodiversity, climate resilience, water quality, and justice wherever possible.

The Southern Rocky Mountain Bioregion extends from the Big Rivers field office in Missouri westward into Utah. It serves as a regional hub for Biohabitats, and its staff support projects throughout the West. Given the breadth of the region’s biodiversity, topography, geography, precipitation, and climate risks, the team here focuses on strategic conservation planning, restoration, and adaptive management related to climate change (including fire regimes), while making every drop count with water management to support and balance natural system functions and human needs.

The Northeast Highlands & Coastal Bioregion’s diverse geography spans mountains to oceans, traversing a glaciated terrain that includes sub-alpine, temperate forest, inland wetlands, rivers, and coastal ecosystems. New Englanders embody a spirit of independence and self-determination that permeates all forms of organizations. Biohabitats brings a nuanced approach to the Northeast by applying innovative natural and nature-based solutions to match the diversity of political, social, and ecological conditions.

Situated at the convergence of multiple ecosystems, including the Rocky Mountains, Chihuahuan Desert, Great Plains, and Colorado Plateau, the Southwest Basin and Range Bioregion is an arid, yet diverse landscape rich with land-based prehistoric, historic, and modern communities that bring unique understandings of the value of water. The Bioregion is the homeland of many indigenous communities, and we work with and learn from the land and people to inform and inspire our broader work with integrated water strategies here and beyond.

Specializing exclusively in ecological restoration construction, the Biohabitats Construction team offers expertise, methods, and equipment specific to this highly nuanced work and a passion for minimizing impact and maximizing ecological uplift.
