Former wildlife agency leaders, scientists, and other natural resource experts line out the requirements for successful policy on this conservation challenge
In a letter to New Mexico Governor Michelle Luhan Grisham, 14 wildlife and natural resources professionals thanked the governor for the state’s leadership on the issue of migration corridor conservation and urged the state to continue its efforts on this critical issue.
These professionals—each with between 20 to 50 years of experience in wildlife and natural resources management, research, and conservation—came together to request that decision-makers in New Mexico build upon the bipartisan support demonstrated by the passage of the Wildlife Corridors Act in 2019, the first-of-its-kind legislation in the country. They emphasized the need for adequate funding and a long-term, holistic view of migration corridor and habitat conservation if the state hoped to succeed in its efforts.
“As a longtime wildlife professional and New Mexico resident, I appreciated Governor Lujan Grisham and the New Mexico Legislature passing the Wildlife Corridors Act,” said Dr. Bill Dunn, a 40-year veteran wildlife biologist and environmental consultant. “This bill is the first of its kind in America and should benefit conservation of migration corridors vital to our wildlife populations.”
In recent years, big game migration has become a priority for conservationists. “We’ve long known the importance of migration to and from seasonal habitats, but new technology has made the importance of these habitats for mule deer, pronghorn and other animals even clearer,” said Dr. Ed Arnett, chief scientist for the Theodore Roosevelt Conservation Partnership.
The letter asks that funding for migration corridor conservation extend beyond coordination and planning for transportation-related issues such as wildlife-vehicle collisions and crossing structures. Currently, the state has only set aside funding under the Corridors Act for such
projects. “It is important,” the signers noted, “for policy- and decision-makers and the public to remember that wildlife corridors may not necessarily intersect highways and roads.”
The breadth of the issue will require the state to utilize funds other than those set aside specifically for game protection, noted the letter, and it “encourage[d] New Mexico legislators to work closely with NMDGF and the New Mexico State Game Commission to ensure adequate funding is made available to support implementation…while maintaining funding for other agency priorities.”
Another challenge highlighted by the letter is coordinating the management of the full suite of habitats required by big game animals as they move across the landscape, including summer and winter range, migration corridors, and stopover habitats. To do this effectively, the state will need to conduct extensive research that could take years to complete. In the meantime, the letter urged state agencies to “develop interim guidance and recommendations while data are being gathered to ensure appropriate management and protection of potentially unmapped corridors.”
Additionally, the letter encouraged the BLM to work proactively with the New Mexico Department of Fish and Game to ensure that energy development on public lands does not disrupt wildlife migrations, as research has shown the impacts to be significant and long-lasting.
“Even though data are still being collected in New Mexico, the weight of existing evidence is clear that development does impact migratory movements and habitat use,” said Arnett. “We should anticipate potential conflicts with wildlife migrations that interface with all forms of energy development and other disturbance.” The signers noted that “Ensuring migration movement and functionality may require the state wildlife agency request leasing deferrals…or implementation of special management recommendations.”
The letter concluded by emphasizing that “the state and federal departments and agencies, and private landowners all must have long-term, institutionalized support for corridor conservation” and encouraged the state “to pursue all avenues that secure long-term support for conservation that will transcend multiple Administrations at both the state and federal levels.
“Healthy populations of mule deer, elk and other big game are a key economic driver for New Mexico’s economy,” says Dr. Ben Brown, a New Mexico resident and retired wildlife biologist with 48 years’ experience in wildlife conservation. “Conservation is a long-term endeavor. Both the state and federal governments need to ensure the functionality of habitat and migratory movements with long-term, institutionalized policy and funding for these efforts.”

I just wanted to put it out there it’s not only public lands but also private land that is land locked the way it is now the rich just take over the land that is land locked they don’t pay the taxes on the private land they use as there own and most don’t have permits for the public land they use as there own and because of there deep pockets nobody will challenge them I’m a land owner who is surrounded by a wealthy ranch who told me they would not give me an easement to my land I ended up finding one that even the county didn’t know about and even though it is 100 percent leagle the ranch is trying to challenge it it is a sad place were the wealthy can force people off the land they own or the public land they have the right to be on and for the most part nothing is done about it they are crooks stealing land because the government won’t do anything and the private land owner doesn’t have the money to fight the rich land thiefs
