ALBUQUERQUE, N.M. - A new report published by the U.S. Geological Survey includes detailed maps of Global Positioning System tracked migration routes for mule deer, elk, pronghorn, moose and bison. The tracking tool will help stakeholders, from conservation groups to transportation agencies, understand how big-game species move across the landscape.

Jesse Deubel, executive director of the New Mexico Wildlife Federation, said the new study maps more than 40 big-game migration routes to provide connectivity among multiple states.

"Wildlife doesn't recognize state borders," said Deubel. "So cross-jurisdictional collaboration when it comes to the management of wildlife, and when it comes to the protection of key wildlife corridors, is absolutely critical."

A poll last year found more than eight in ten residents of New Mexico and Colorado support protecting wildlife migration routes.

Deubel said in the Gila region, all kinds of species are moving between New Mexico and Arizona - but it isn't a seasonal migration. Instead, big-game animals are looking for water.

Forest fires, many due to climate change, also affect big game migration in New Mexico. That's another important reason to maintain habitat connectivity, according to Nicole Tatman - big game program manager with the state's Department of Game and Fish.

"Animals will move out of an area when a wildfire is occurring," said Tatman. "But they'll move back into that area after the fire has gone and maybe rains have come and brought up some green vegetation that they can take advantage of."

In addition to wildfires, drought can make finding that green vegetation harder for big-game animals, according to Matthew Kauffman, wildlife researcher with the U.S. Geological Survey.

Kauffman, the report's lead author, said food is often absent along ancient migration corridors.

"Drought disrupts that 'green wave,' and makes it more difficult for animals to surf," said Kauffman. "They still try, they do their best given the drought conditions, but they just can't be in the right place at the right time."

The new study builds on more than two decades of research by state wildlife agencies including GPS tracking-collar data, mapping migration routes in Arizona, Idaho, Nevada, Utah and Wyoming.

The Mexican Gray Wolf population in Arizona is on the rise.

For the first time since reintroduction into the wild, the population of wolves across Arizona and New Mexico sits at more than 240, with 105 of them in the Grand Canyon State.

According to the U.S. Fish and Wildlife Service, last year's population represents a 23% increase from the 196 wolves seen in 2021.

Craig Miller, senior representative in Arizona for the nonprofit Defenders of Wildlife, has been involved with Mexican gray wolf recovery efforts since the beginning. The group is celebrating the 25th anniversary of the wolf's reintroduction. He said collaborative efforts among agencies, conservation groups and the public are to credit for the recovery.

"At the end of the day, the decision was made to proceed with reintroduction," he said. "In 1998, I had the privilege of witnessing the return of one of the most endangered land mammals the world."

Miller said his organization over the years has managed to create partnership projects that have led to the reduction of vulnerability to wolf depredation. He added that the partnerships and projects to help the Mexican gray wolves are updated and improved every year.

Regardless of the tools used by ranchers and farmers to mitigate livestock predation, he said, there will continue to be incidents involving wolves. However, Miller stressed the tools are far less important than the partnerships that have evolved from experimenting with different management strategies.

"There are a lot of tools that we can use to reduce conflicts between wolves and livestock, but by far the best tool is the human mind," he said. "And the best way to use the human mind is by connecting with others with diverse experience and diverse perspectives."

Miller said flags, air horns, electrified fencing and strobe lights are all ways in which wolves are deterred from pursuing domestic livestock and encouraged instead to pursue natural prey.

Some $20 million of Utah's whopping $29 billion state budget will be spent on building wildlife crossings and fences across the state in an effort to keep wildlife off of highways.

Rep. Doug Owens, D-Salt Lake, said the appropriation is "non-lapsing," meaning the funds can be spent over time. Owens added the federal government needs to approve a four-to-one match, which would make a grand total of $100 million available for the projects statewide.

"That is a lot of money for fencing, and crossings and underpasses," Owens pointed out. "Hopefully we'll get all that $100 million spent here in the next few years, to keep our roadways safe."

Owens noted before the legislative session began, he asked the Utah Department of Transportation to put together a list of the top 10 hot spots where wildlife mitigation projects are needed most. He added with the estimated cost of the projects, $100 million will be enough to fund them.

An estimated 5,000 deer and 1,000 elk are involved in vehicle collisions in Utah every year.

Owens argued the number of large animal and vehicle collisions needs to come down, to prevent injuries and deaths for humans and animals alike, as well as the material damage. He called the appropriation a "win for everybody."

"Utahns incur about $130 million of expense every year fixing cars that have hit animals," Owens reported. "And that doesn't even include any of the medical costs, and even the occasional fatality of a person hitting a large animal."

Utah made history in 1975 as the first state to complete a wildlife overpass on Interstate 15 near Beaver. Since then, more than 100 projects have been executed, and Owens added he is excited to see more implemented around the state.

As part of the Inflation Reduction Act, the Interior Department has announced it is investing $120 million to restore and rebuild key segments of America's wildlife management systems, especially in key areas of the Midwest.

The money will be used to address species climate adaptation and invasive species threats, and provide additional data collection needed to support successful natural resource resilience. The money will be especially important in high-priority areas of the Midwest known as Prairie Potholes.

Christy Plumer, chief conservation officer for the Theodore Roosevelt Conservation Partnership, said the potholes are shallow wetlands where wildlife have been threatened.

"It is what we call the duck factory," Plumer explained. "A lot of waterfowl species spend really important components of their life within the Prairie Pothole region. It is a region that has a complicated set of both threats and opportunities within it."

Some $23 million is earmarked for landscape conservation and restoration in parts of Iowa, Minnesota, Montana, and North and South Dakota. The investment comes at the same time the Endangered Species Act turns 50 years old.

Plumer added much of the $120 million investment will go right to work on the land of individuals who want to protect sensitive, low-lying wetlands on their property ...

"... but still utilize the upland areas for growing crops, ranching and for other needs," Plumer emphasized. "I think a program like this provides that blend of opportunities for willing landowners to do great conservation work while also thinking long term about the economic vitality of their farms and their ranches."

Plumer noted in addition to restoring habitat and increasing land resilience, the Prairie Potholes project will also secure environmental justice for historically disadvantaged communities.
