The INVEST Act would protect and restore wildlife corridors and provide significant funding to reduce wildlife-vehicle collisions nationally

WASHINGTON, D.C. (July 2, 2021) — Marking a significant step for wildlife conservation, the Wildlife Corridors Conservation Act along with $400 million for projects to reduce wildlife-vehicle collisions, passed the United States House of Representatives as part of H.R. 3684, the INVEST in America Act. These important provisions will safeguard biodiversity while helping stimulate the U.S. economy, mitigate climate impacts, and reduce highway fatalities.

With one in five species in the U.S. at risk of extinction, biodiversity loss and the disruption of natural wildlife habitats are among the nation’s greatest conservation challenges. Connecting habitats by protecting corridors and building highway crossing structures for wildlife enables species to migrate, access resources for survival, and better adapt to changing landscapes and climate. Indeed, a new report from a biodiversity and climate change workshop co-sponsored by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and the Intergovernmental Panel on Climate Change (IPCC) calls for corridors as part of an integrated strategy to address both climate change and biodiversity loss.

The bipartisan Wildlife Corridors Conservation Act was introduced in the last Congress by Representatives Don Beyer (D-VA) and Vern Buchanan (R-FL). The Act accomplishes the following:

  • Grants authority to key federal agencies to develop a National Wildlife Corridor System on federal public land;
  • Dedicates $50 million per year to a Wildlife Movement Grant Program that will incentivize the state and tribal agencies and interested private landowners to improve habitat connectivity on non-federal lands;
  • Contains the provisions of the Tribal Wildlife Corridors Act, previously introduced by Representative Ruben Gallego (D-AZ), which provides funding and support for Tribal Nations to establish and manage wildlife corridors on tribal lands; and
  • Creates a National Wildlife Corridor Database—which will be freely available to states, tribes, federal agencies, and the public—to support decisions about wildlife corridors and develop strategies to enhance habitat connectivity.

“With time running out to protect key iconic species, the House just took decisive action by passing the Wildlife Corridors Conservation Act,” said Representative Don Beyer (D-VA). “Years ago, during my first term, I had the opportunity to meet with one of my heroes, the legendary Dr. E.O. Wilson; his argument for protecting biodiversity and his proposed solutions for doing so were the seed of this legislation. As he pointed out, simply providing wildlife the opportunity to move across lands and waters is one of the simplest and most effective ways to help preserve the many species in the U.S. at risk of extinction due to habitat loss and fragmentation. This is a great day for wildlife protection.”

Connecting wildlife corridors is a conservation strategy that is gaining broad support across the country. In 2021 alone, three states—Florida, Virginia and Colorado—have passed bipartisan legislation to protect wildlife corridors. To date, 14 states have introduced wildlife corridor legislation or issued executive orders, and nine of those states have passed the legislation. While states are initiating wildlife corridor and crossing protection, federal funding and technical assistance is needed to fully to implement these emerging state policies and projects. The INVEST in America Act provides access to significant dollars for landowners, states, federal land managers and tribes to work together to collaboratively protect wildlife.  

“Protecting wildlife corridors is one of the most important tools we have to address the biodiversity crisis, especially in the face of climate change,” said Susan Holmes, Federal Policy Director at Wildlands Network. “By investing in wildlife road crossings and providing funds for states and tribes to protect wildlife corridors, this bill will safeguard biodiversity and protect motorists while rebuilding infrastructure. Wildlands Network thanks the members of the House of Representatives who have championed wildlife corridor and crossing provisions and urges the Senate to quickly pass this important legislation.”

Reported collisions between motorists and wildlife cause more than 200 human fatalities and over 26,000 injuries each year, at an annual cost to Americans of more than $8 billion. More than one million large animals are killed annually by motorists on U.S. roads—roughly one every 26 seconds. Numerous research studies show that wildlife crossing structures and fencing that guide animals over or under our nation’s highways are highly effective, reducing wildlife-vehicle collisions by up to 97%.

Within the INVEST in America Act is the five-year reauthorization of the surface transportation bill, which:

  • Includes $400 million in dedicated funding for wildlife-vehicle collision reduction projects from a competitive grant program; and
  • Allows state and federal agencies the option to utilize other program dollars for projects that improve habitat connectivity; and
  • Provides training opportunities and research and data support to assist states to more effectively study wildlife-vehicle conflict and prioritize needed projects.

These provisions complement language included in S. 1931, the Surface Transportation Reauthorization Act of 2021 (STRA) that the Senate Environment & Public Works Committee unanimously passed in May 2021. Such funding will support state, tribal and federal efforts to protect motorists and allow wildlife to safely cross highways.

The bill is supported by nationally recognized scientists, including renowned biologist Dr. E.O. Wilson, recreation companies including Patagonia and more than 220 prominent NGOs nationwide.

“By securing funding for wildlife crossing structures and protections for wildlife corridors, the INVEST in America Act creates safer passage for both people and wildlife across our nation’s highways,” said Gary Tabor, President of the Center for Large Landscape Conservation. “Connecting habitat and protecting migration routes allows wildlife to move safely across landscapes in order to find food, mates, and refuge in a changing world. Additionally, reducing wildlife-vehicle collisions and conserving ecosystems will save money and create jobs in green infrastructure and outdoor recreation. The legislation passed by the House today is a smart economic investment and positions the U.S. as an international leader in habitat connectivity and biodiversity conservation.”

“Ensuring safe passage and migration routes for park wildlife is a commonsense and forward-thinking solution, as climate change and habitat loss threatens park wildlife and ecosystems across the United States, said Bart Melton, Wildlife Program Director at National Parks Conservation Association. “From a black bear safely crossing the road at Shenandoah to the 250,000 strong herd of Western Arctic Caribou migrating across the vast tundra at Gates of the Arctic, critical action is needed to protect, restore, and connect habitat and travel routes for national park wildlife. The INVEST Act is a vital next step in collaboratively addressing the challenges facing national park wildlife today and for the long-term.”

“This bill is truly a win for both people and wildlife,” said Curt Chaffin, Senior Government Relations Representative at Defenders of Wildlife. “Habitat destruction is one of the main drivers of the biodiversity crisis. Investments that address habitat connectivity and protect wildlife and the places they call home are an essential part of the solution. These wildlife infrastructure provisions will protect biodiversity, increase public safety and create local jobs.”.

“Habitat fragmentation is a major driver of species decline and an impediment to recovering imperiled wildlife,” said Leda Huta, Executive Director of the Endangered Species Coalition. “We thank the bill sponsors and supporters for recognizing the important role of corridors in helping our fish and wildlife migrate and move about the landscape.”

“It is fitting that the surface transportation bill includes the Wildlife Corridors Conservation Act as millions of drivers and wildlife are affected by wildlife-vehicle collisions and other problems associated with road construction and other developments that fragment habitats and migration routes,” said Sara Amundson, President of the Humane Society Legislative Fund. “Representatives Beyer and Gallego have been tireless champions in pushing for a national wildlife corridors system that will reconnect these vital habitats across federal, state, tribal, and private lands. Protecting drivers and wildlife go hand in hand here, and we’ll continue fighting to ensure this language makes it all the way through to law.”

“Habitat loss and fragmentation are leading drivers of biodiversity loss, fueling a worsening extinction crisis that threatens not only wildlife, but also the health of the critical ecosystems we rely on for our basic needs,” said Kate Wall, Senior Legislative Manager at the International Fund for Animal Welfare. “Wildlife corridors and crossings protect biodiversity by allowing wildlife to move safely in response to ever-changing conditions. These pathways not only help to maintain healthy wildlife populations, they also help protect human health and wellbeing by preventing collisions, promoting resilient ecosystems, and mitigating climate impacts on native species. We applaud the House for including support for wildlife corridors and crossings in the INVEST Act.”
