PHOENIX - Nearly a million acres of public lands, mainly in western Maricopa County, which has Phoenix as its seat, would be preserved as wilderness, national conservation and special management areas under a bill introduced by Arizona Congressman Raul Grijalva.

According to Grijalva, the measure would benefit wildlife, the state's military bases, and the tourism economy.

"One of the key ones is of course the environmental protection that would come, the conservation that would be locked into place, and as a money maker for the state, those would be protected for the long haul," the congressman said.

He said the Air Force's Barry Goldwater Range would also be protected from encroachment by development.

The Arizona Sonoran Desert Heritage Act is the result of years of work by a diverse collection of interests, including conservationists, developers, and military interest groups.

A major goal of the legislation is protection of flight corridors on the Goldwater Range, used for pilot training by several military bases in the state. According to the Range's retired director, Jim Uken, both the military and wildlife, such as the endangered Sonoran Pronghorn Antelope, stand to benefit.

"To me it's more than a natural marriage because we would like to preclude further urbanization underneath those corridors, and those same corridors then could serve as wildlife corridors between different areas to the west of Phoenix, for example," Uken said.

Ron Sites is president of Fighter Country Partnership, a non-profit advocacy group for Luke Air Force Base. In addition to protecting Luke's military training routes, Sites said, the Sonoran Desert Act will provide a buffer around the Goldwater Range.

"If they run into a situation where there's endangered species on some of the lands that are off the range, and because of development they get forced onto the range, those create some challenges for the Department of Defense and the Air Force when they're managing those lands," he said.

Grijalva said his bill will not affect hunting, game and fish management, existing grazing permits or utility corridors. And it deals only with public lands.

"There's no taking, there's no eminent domain, there is no private land," he declared. "These are already federal land. We're doing a consolidation. Some have been redesignated as wilderness, but essentially, we're talking about no additional acquisition."

Grijalva said he's heard no objections to his bill from the rest of the state's congressional delegation, and hopes several of them will sign onto the measure as co-sponsors.

Arizona conservation groups and sportsmen alike say they're pleased the Bureau of Land Management will now recognize conservation as an integral part of public lands management.

The agency's new rule puts protecting the environment on par with other land-use priorities.

Scott Garlid, executive director of the Arizona Wildlife Federation, said historically the BLM has done what he termed a "pretty good job," not only managing about 12 million acres of public lands in Arizona, but also protecting natural resources.

"They've got a tough job," Garlid acknowledged. "I think this rule helps make their job a little bit easier because it gives them some tools to balance those different demands on the 12 million acres that they manage."

Garlid predicted the rule will raise what he terms "harder-to-quantify conservation values" to the same level of importance as more extractive land uses like oil and gas exploration and mining. He thinks most Arizonans will recognize the new rule as a positive. A solid majority of Arizona voters across party lines say they are conservationists and use public lands for recreation.

To Garlid, the rule makes it clear the BLM is recognizing certain parts of federal lands, in Arizona and around the West, have been degraded. He contended restoration leases will be a good tool, allowing the BLM to lease acres to groups specifically to improve the conditions on a given landscape. He noted opponents of the new rule might see the leases as a way to "lock up" land but he argued it is not true.

"One example could be a nonprofit, like the Arizona Wildlife Federation," Garlid pointed out. "We could get a conservation lease from the Bureau of Land Management to do riparian restoration work, or work to remove invasive species along a creek bank."

According to the BLM, while a restoration or mitigation lease is in place, casual uses of the leased lands like recreation, hunting, fishing and research activities would generally continue.

State and federal agencies are collaborating to increase the use of prescribed fires in the Northwest.

Prescribed fire is the controlled use of burns to minimize the larger risks of wildfires and smoke. It is seen as an increasingly important strategy as wildfire seasons pose greater threats to the Northwest.

Casey Sixkiller, Northwest regional administrator for the U.S. Environmental Protection Agency, said authorities want to work together to maintain forest habitats.

"Prescribed burn is one of the best tools we have for making our forests more resilient against catastrophic wildfires and they help to manage and target hazardous fuels and make for healthier forests," Sixkiller explained.

Sixkiller pointed out the EPA is involved because wildfire smoke poses risks to people's health. The collaboration is between federal agencies, departments in Oregon and Washington, and tribal governments.

Sixkiller noted the collaboration needed a formal agreement to move forward.

"That is what we've been able to do here with this agreement," Sixkiller emphasized. "To get federal land managers and states and us all in the same room, making sure that we're all on the same page about what success looks like."

Sixkiller added the collaboration has another advantage: It helps drive engagement with communities potentially in the path of prescribed burns.

"They have the confidence that the effort that's gone into planning that activity has been thought out from soup to nuts," Sixkiller acknowledged. "And that they have a seat at the table and are being engaged and their concerns are being addressed as we go forward with that activity."

A new study in the journal Nature Communications by Montana researchers said suppressing small wildfires is leading to larger, more intense and damaging blazes.

According to the U.S. Forest Service, about 98% of wildfires are fully suppressed before they grow to 100 acres; most of them within 72 hours. In Montana, the latest data show crews kept 95% of wildfires in Montana to no more than 10 acres in 2022.

Mark Kreider, a doctoral candidate in forest and conservation science at the University of Montana and co-author of the report, said the strategy leads to what is known as fire "suppression bias."

"Removing more of one type of fire than the other, what we're left with is bias towards the higher intensity fires, these more extreme fires," Kreider explained.

Montana state policy calls for crews to extinguish fires as quickly as possible, even small ones. Kreider pointed out researchers recommend letting low-intensity fires burn where possible to reduce the risk and damage potential for larger, hotter-burning and more catastrophic blazes.

Kreider acknowledged as the population grows along the urban-wildland interface, letting fires burn is not always possible, but argued it might be the best strategy for heading off catastrophic fires later.

"Especially in the western U.S. where people live close to forests, fire suppression is very important and we still must do it," Kreider noted. "But this research helps to show when possible in places where it's safe to do so, we really may benefit from allowing more low and moderate intensity fire to burn."

The National Interagency Fire Center said the number of acres scorched by wildfire has doubled since the 1980s, and the cost to battle the fires has risen to nearly $3 billion a year.
