An endangered bat species has been detected in southeastern Arizona.

Researchers say the discovery of the Mexican long-nosed bat in the Grand Canyon State expands the known range of these animals. They're important pollinators for desert plants such as columnar cactus and agave.

Kristen Lear, program director for Bat Conservation International's agave restoration program, said knowing that this endangered species has been found in Arizona opens up new avenues for research and conservation.

"Some of the work for the conservation of the species for the Mexican long-nosed bat are really two things," she said. "One is roost protection, finding the caves, the mines or wherever this bat is roosting along their migratory route and protecting those roosts. And then the second aspect is maintaining healthy foraging habitat."

Lear said the discovery of the tiny bat was made possible as project participants collected what's known as environmental DNA, or eDNA, by swabbing hummingbird feeders that bats also feed on. When bats feed, they leave traces of DNA behind through their saliva, which can then be analyzed.

As bats continue to struggle to survive because of disease and habitat loss, Lear said, it is important to study them using non-invasive methods.

Mexican long-nosed bats migrate annually from south-central Mexico to the southwestern United States, spending the summer months in southwest Texas and also in the bootheel of New Mexico. However, Lear said the bats' appearance in the Grand Canyon State could be a sign of the impacts climate change could be having on migratory practices.

"We're seeing more bat species using the edge of their ranges in areas that they aren't usually found," she said, "and so that could be what is happening here, is that climate change modeling with the agave plants, that are their food source, all of the modeling shows that that area is actually going to become more important for these bats in the future."

Lear said surveys have also increased in recent years, and it is possible the Mexican long-nosed bat has been in southeastern Arizona in low numbers but simply hadn't been detected yet. She said she wants to encourage Arizonans to plant native night-blooming plants, which attract insects for insectivorous bats to eat and agaves for nectar-feeding species, such as the Mexican long-nosed bat.

The Mississippi River is the drinking water source for 20 million people and its starting point in northern Minnesota has new protections following completion of a deal to preserve several thousand acres of forested land.

The Conservation Fund and Northern Waters Land Trust said the deal, years in the making, covers more 8,200 acres across nine counties between Walker and Duluth.

Emilee Nelson, associate Minnesota state director for The Conservation Fund, said her group purchased a larger chunk of land in 2020 and since then, the Land Trust worked to secure state funding for the acreage in the deal. She pointed out downstream, the river has seen surrounding land converted to other uses, which takes away key buffers.

"The importance of leaving forests on the landscape really helps to soak up water that hits the landscape like a sponge," Nelson explained. "It helps to filter any sort of debris before it hits the Mississippi River."

Separate plans are being finalized with county governments to ensure permanent management and public access to the lands. Nelson emphasized it should benefit hunters and anglers, while protecting wildlife habitat. She added the timing is important with political pressure on the landscapes for possible industrial uses. Rep. Pete Stauber, R-Minn., is part of the push, citing the need for jobs.

Nelson pointed out with such a deal, local timber companies can still benefit from effective forest management, including the need to clear out dying trees.

"When we own it, we would contract with local loggers to help do prescribed thinnings, and to then deliver lumber to local mills, like in Bemidji," Nelson noted.

Organizations involved in the deal said it will protect jobs in the outdoor recreation and tourism sector.

Access to the beloved Pacific Crest Trail may soon be limited - due to a drop in federal grants and big layoffs proposed for federal public lands agencies.

In the next two weeks, the Trump administration is expected to release the reduction-in-force targets for the National Park Service, U.S. Forest Service and the Bureau of Land Management.

Megan Wargo, chief executive officer of the Pacific Crest Trail Association, said federal grant money dried up last October, so they've had to cancel 56 weeks of crew maintenance work on the trails.

"If large sections of the trails are forced to be closed because of this lack of maintenance and care, that's devastating that folks won't be able to access their public lands because of these cuts," she explained.

Volunteers help keep the trails clear of debris and repair erosion from storm damage. The Pacific Crest Trail runs more than 2,600 hundred miles from Mexico to Canada and includes landscapes from Anza Borrego in the South, to Sequoia, Kings Canyon, and Lake Tahoe in the Sierras, and points north.

Wargo said the National Trails System Act calls for a public-private partnership to manage the national scenic trails. The Pacific Crest Trail Association normally gets between $667 million per year in federal funding - about a quarter of what it needs to help maintain the PCT.

"Typically, that breakdown is about 25% value that's coming from the federal government, while the other 75% is coming through private donations and that volunteer service hour value," she continued.

Wargo added that cuts to the federal workforce hobble agencies' abilities to make grants and approve volunteer projects. And that means less brush gets cleared, raising the risk of wildfires in California.

April is National Native Plant Month, an observance at the core of South Dakota's identity.

People wanting to protect the state's beloved grasslands encourage landowners in urban and rural areas to set aside growing space. South Dakota's prairies often conjure up images of species like tallgrass, which have deep roots good at absorbing water. But some varieties have not fared as well because of different types of land use. The World Wildlife Fund said only 53% of the Great Plains region's grassland remains intact.

Drew Anderson, a farmer, rancher and conservation advocate from Lemmon, conserves native plants, noting every little bit helps, and they do not have to just grow in rural settings.

"There's just a growing appreciation for the native grasslands that are making their way into urban areas," Anderson pointed out. "People are using big bluestem in front of commercial buildings and places like that."

The desire is reflected in a recent ad campaign from the South Dakota Grasslands Coalition and statewide polling. In a survey commissioned by the group, there was broad bipartisan support among voters to prioritize effective grassland management. Anderson added patience is a challenge they are up against because it can take a year or two to see real evidence of native plant growth.

Anderson added it is not just livestock grazing standing to benefit from an abundance of grasslands.

"The grasses help provide habitat for many different wildlife species, whether it's migratory songbirds (or) pollinators," Anderson emphasized.

If you want to grow some native plants on your property but are unsure how to get started, Anderson recommended visiting your local Natural Resources Conservation Service office. The Grasslands Coalition also has guidance and other key information on its website.
