He blew up a lot of dams.

He waged war against the animals here in northeastern Nevada. It wasn't from meanness or cruel, it was a struggle over water. Some parts of Cottonwood Ranch were flooded and others were dried out by the animals.

Agee took over the ranch after his father died. One of the best things he has done is to welcome the beavers to work on the land.

Mr. Smith said that they are very controversial. It's getting better People are waking up.

Mr. Smith is one of a growing number of ranchers, scientists and other "beaver believers" who see the creatures not only as helpers, but as furry weapons of Climate resilience.

When Nevada experienced one of the worst droughts on record, he kept his cattle with enough water. The vast network of dams slowed a torrent of water that was raging down the mountain. Wetlands that run through the sagebrush desert have been widened thanks to the help of the beavers.

It's true that beavers can be complex partners. They swim rodents the size of basset hounds, obsessed with building dams. You can't talk about conflicts when they happen.

People want the area to be dry. They didn't think about whether humans would like the trees to stand. The federal government killed a lot of beavers.

Beaver ponds store water. In an increasingly parched West, that’s crucial.

A lot of water is stored for free by the beavers. They help with a lot more than just the dry spell. Slowing water is what they do to subdue floods from heavy rains. It replenishes the ground. The wetlands created by the beavers may be able to store carbon out of the atmosphere.

The rodents tackle another crisis unleashed by humans: rampant biodiversity loss. Wetlands are being recognized for their creation of habitats for many species.

They are having a moment. In Colorado, Idaho, Montana, Nevada, Oregon, Utah and Wyoming, the Bureau of Land Management is working with partners to build beaver-like dams that they hope will grow. The new state budget in California restores animals for climate resilience and other benefits.

Wade Crowfoot, California's secretary of natural resources, said in a webinars that they need to get the animals back to work. Full-time work for beavers. Animals work for free, that's what believers like to point out.

The job market in the east isn't as hot as it is in the west. There are more than one project. In Maryland, groups are trying to clean the water in the bay. Some of the most vulnerable areas of Milwaukee County have been found to be greatly reduced by the presence of beavers.

Chris Jordan and Emily Fairfax of California State University Channel Islands believe that the federal government should embrace beavers as an important component of federal climate adaptation.

Dr. Jordan and Dr. Fairfax wrote in the journal WIREs that the reality is that they are a force of 15-40 million highly skilled environmental engineers.

The recent research done by Dr. Fairfax focuses on how the animals interact with fires. She found that they are too wet to be burned. She said that climate change could cause that to change.

They couldn't afford to work against them anymore. They need to be worked with.

Project evaluations should be done on a case-by-case basis according to a river scientist at the consulting firm.

Dr. Nash said that it was important to identify the locations where the survival interests of the beavers and humans were compatible. It is a recipe for broken hopes and expectations and a loss of trust if you suggest that they will always be aligned.

The landscape and hydrology of North America were shaped before Europeans arrived. Their fur was popular in Europe for felted hats, but they were almost wiped out by trappers. Conflicts came as their numbers climbed back in part because of reintroduction programs. People in low-lying areas didn't like the idea of their property being returned to wetlands.

Mr. Smith said “people are starting to wake up” about beavers.

Beavers use logs, sticks, stones and mud to build dams that help them dodge bears. They store food below the surface for winter. The iron in the teeth of the beatiful strengthen them for gnawing trees.

Humans and animals can be solved without killing each other. Fence and paint can protect trees. The pipes that drain the water from the settlements of the beavers are hidden by the systems. According to advocates, such measures are more effective than removing the animals because they tend to move into empty habitats.

A growing number of groups and private businesses are looking to relocate if coexistence is not possible.

The Tulalip Tribes, a federally recognized tribe just north of Seattle, has a policy of moving unwanted beavers to land managed by the United States Forest Service.

The group wanted to expand the extraordinary habitat that is offered to salmon, a culturally and economically important species. The Tulalip Tribes had to invoke their treaty rights to relocate beavers because they weren't allowed in their area. The tribes are advising the state on a program to train others in best practices after lobbying for the legal relocation of the beavers.

The lesson was to keep the families together.

If their entire family is there, they are more likely to stay there. There are a lot of tight-knit family bonds.

In many states it is illegal to relocate animals because officials worry that people will move the problems elsewhere.

The killing of beavers is officially done by the government. Suzanne Bond, a spokeswoman for the United States Department of Agriculture, which runs the program that kills tens of thousands of beavers each year by trapping, snaring and shooting, said the agency was reviewing the relevant science.

During the spring snow melt, the sides of the dams would fail, causing damage to his hayfields. The younger Mr. Smith tried a different approach to cattle management, moving them around his land and allowing them to spend less time around the creek. The shrubs and trees along the banks made the area more stable. The surge of water would stay in the channel if the dam gave way.

Birds expanded the wetlands. There was a new meadow growing in the area. The willows sprouted from the roots of the animals. There is no water in the picture. The fish and frog are back.

If they build dams in our irrigation ditches, the only time we'll crossways with them will be then. We know how to discourage them from doing that. He said that pulling out the dams a couple of times is the best way to do it.

Mr. Smith has flexibility that has helped the partnership succeed. One section of the creek has been completely rearranged by the animals. Mr. Smith doesn't see the change as positive or negative. He said that the most important thing was the amount of water on the land.

He said that water is gold.
