United States Connectivity

Creating Safe Passage for People and Wildlife

Animals need to move to survive and thrive. We use science such as spatial models and maps to help planners throughout the U.S. identify how and where animals move across the landscape, and how people help or hinder that movement. We apply this knowledge to support on-the-ground action, from helping wildlife safely cross roads to identifying and protecting vital ecological linkages.

In addition to this technical guidance, the Center provides policy advice and expertise. We work with national, state, and local decisionmakers and stakeholders to collaboratively develop, advance, and implement policies that protect wildlife movement, improve habitat connectivity, and support conservation at the landscape scale.

Integrating Habitat Connectivity into Local Planning

Local governments have land use authority across nearly two-thirds of land in the U.S. and have a key role to play in preserving wildlife habitat connectivity. In recognition of the importance of local action, we’ve created a new report on wildlife connectivity and local government to bring together the policy tools and practical strategies that every community and community member—whether you’re a resident, planner, biologist, developer, or legislator—can consider using to help keep our landscapes connected.

Creating Safe Passage for Desert Tortoises

Desert tortoises need to move—and often cross roads—to find food, to reach water, and for other activities essential for survival. Unfortunately, this threatened species is being struck and killed by the thousands each year by motorists in the southwestern US, and their population numbers continue to decline. The Center is working with the US Fish and Wildlife Service and other public and private partners to minimize tortoise deaths along roadways. The initiative aims to establish standard policies and practices that can be implemented consistently across the desert tortoise’s four-state range, with the goal of providing these animals with habitat connectivity and safe passage across roads.

US-191 Wildlife Crossings Project

The Greater Yellowstone Ecosystem is home to the largest concentration of wildlife in the lower 48 states. But as the numbers of area residents and visitors have grown, so has the incidence of wildlife-vehicle collisions. On US Highway 191 through and around Yellowstone National Park, large mammals like elk and deer are hit with increasing frequency, and rising traffic volumes make it harder for wildlife to access habitat on either side. To address these problems, the Center for Large Landscape Conservation and Montana State University’s Western Transportation Institute embarked upon a two-year study to better understand wildlife movement and improve road safety along this busy route.

Recommendations for State Wildlife Action Plans

State Wildlife Action Plans (SWAPs) are important vehicles for connectivity conservation that state wildlife agencies must complete to qualify for a federal funding program designed to conserve at-risk species and their habitat. SWAPs are recognized as “conservation blueprints” that compile the best available science, identify conservation priorities, and promote coordination across various partners. A report prepared by the Center provides SWAP planners and partners with a comprehensive “menu” of actions and recommendations for addressing habitat connectivity. Learn more
