The California Fish and Game Commission delayed the decision again today over whether to grant state protection to the western Joshua tree.

The petition to protect the plant under the California Endangered Species Act (CESA) was submitted in 2019. If it is listed, it would be the first species to earn protection in the state because of climate change.

But the process has been contentious. And even when the decision is made, the fate of the plant is far from sealed.

How to save a tree

A member of the public must make a case to the California Fish and Game Commission that a species needs protection. In this case, the case is over the western Joshua tree, which primarily grows in California.

Their champion is Brendan Cummings. As conservation director for the Center for Biological DiversityCenter for Biological Diversity, he's litigated plenty of endangered species cases. "Fifteen or so years ago, I did the ... litigation that forced the Bush administration to protect the polar bear under the Federal Endangered Species Act."

But this species is personal. He's got dozens of them in his backyard in the town of Joshua Tree. "If you look around us here, the adult Joshua trees we're seeing were recruited into the population under a climate that no longer exists," he says.

But the case he's making isn't easy. Millions of these trees are still spanning thousands of square miles. Listing a species means businesses and residents must either avoid killing it if possible, or move it, or pay a fee if it must be killed. With so many trees left, that could be burdensome.

Kelly Herbinson says it's worth the trouble. She's the co-executive director of the Mojave Desert Land Trust, whose whole mission is to set aside acres of desert habitat for preservation.

"What we're seeing right now is unprecedented. This is serious. And I don't know that that's always obvious if you're not doing this every day and working on the land every day," she says.

At lower elevations, the western Joshua tree is facing the effects of the worst drought in more than a thousand years. "If you were to go to, say, the West Mojave, or even areas nearby where the drought has been really bad, I mean, they're mostly brown," she says.

In its middle elevations, the Joshua tree has been separated into small island habitats by decades of development as the human population in the desert continues to grow. That cuts off genetic flow between populations and creates problems like what LA's mountain lions are facing.

And then of course, at its middle and higher elevations, the Joshua tree is facing a threat it rarely encountered before: increased wildfire.

On a protected parcel of land across the street from where Herbinson works, a stray cigarette in 2020 burned most of the Joshua trees on a quarter of the 600 acres that the Mojave Desert Land Trust saved from becoming a housing development.

"That is not something that happened historically," she says. "There's this massive overgrowth of invasive plant species that are blanketing the desert and creating this massive fuel load. And then it dries out because we're in a drought. And then you just have this carpet of dried up plants that are ripe to burn."

There's also the problem of the tree's lifelong partner: the yucca moth. They're completely reliant on each other to survive.

The moth lives underground at the base of its tree for years, waiting for it to flower, and in the spring when it finally does, it emerges and pollinates the tree in exchange for food and a safe place to produce larvae.

But as the climate changes, scientists have found that the moths aren't reproducing like they used to.

The California Department of Fish and Wildlife spent months studying the trees. Their job is to provide all the data and expertise that the commission needs to make a decision. In June, the department determined that there isn't compelling evidence that the western Joshua tree is in danger of going extinct in the foreseeable future. It said the plant has time to adapt to climate change.

Almost all of the peer-reviewed scientists disagreed. At the meeting in June, hundreds of members of the public showed up to throw in their opinion too.

Local politicians, the local water board, building developers, and labor unions all argued that listing an abundant plant in the desert as endangered would hurt development and jobs.

National politicians, conservationists, scientists, local residents, and tribal groups all made the case that the western Joshua tree is disappearing, and needs to be protected.

The commission reached a stalemate in June, and then on Wednesday they decided unanimously to delay the decision again, to leave room for more tribal consultation.

Cummings says he is not surprised by the delay. But even if the commission lists the western Joshua tree next year, he doubts the fight will end there either.

"If they vote to protect Joshua trees, various business interests will undoubtedly sue, trying to overturn that protection. And conversely, if the commission votes against protecting Joshua trees, I will sue, attempting to overturn that unlawful, unscientific decision. So the future of the species is likely to be contested for the next few years," he says.

For now, the Joshua tree has temporary protection, since it is a candidate species for CESA. The commission will revisit the decision in February 2023.

An environmental group is suing the U.S. Fish and Wildlife Service to protect the Arkansas mudalia snail under the Endangered Species Act.

In Arkansas and Missouri, including along the North Fork River, mudalia are critically endangered freshwater snails.

Trisha Sharma, legal fellow at the Center for Biological Diversity, emphasized the need to save the snail from vanishing entirely. She said freshwater mollusks are the most endangered group of animals in North America, and snails are the most endangered mollusks.

"We've already lost more than 70 species of freshwater snails," Sharma pointed out. "The Endangered Species Act has a very high success rate. So if we can get it listed and protected under the ESA, it's highly likely that the species will survive and be able to continue playing its important role in the ecosystems where it's found."

Sharma noted areas where the Arkansas mudalia can be found have decreased by 90% and the main threat to the species is habitat degradation, primarily from dam construction and operation along the rivers.

Sharma emphasized mudalia is also threatened by habitat loss from grazing, logging and mining. She added climate change is also expected to threaten the species.

"Part of what can make a species more resilient to climate impacts is its ability to disperse as its habitat becomes unsuitable, and to essentially relocate to areas where it can survive," Sharma explained. "But snails have a pretty narrow set of habitat requirements and very limited dispersal capabilities."

Sharma said freshwater snails play a crucial role in managing nutrients by consuming detritus and plant matter, preventing their decay and subsequent disruption of water quality, and snails are vital for food webs, converting unusable food sources into usable ones for birds and turtles.

Today is Earth Day, and one initiative in southern Arizona is helping build public gardens providing beneficial habitat for pollinators, from Monarch butterflies to bees and bats.

Emily Bishton, founder and coordinator of the Arivaca Pollinator Pathway Project, said the human population depends on these animals and insects, as many of our foods and plant-based products require pollination. But human activity and climate change have put pollinators in jeopardy and Bishton wants to increase awareness of how crucial they are.

"The best chance you have for attracting and nurturing pollinators is with the species that they've co-evolved with," Bishton explained. "They will instinctively know that is food for them, or a place they can lay their eggs. They also are more likely to be able to put up with the way our climate is now and the way it is changing."

Bishton pointed out one focus of the project is to get Arizonans to plant more native species like milkweed, which is especially critical for Monarch butterflies. She would also like people to reconsider the use of pesticides since they do kill pests but also other beneficial insects. She suggested contacting a local county extension service or master-gardener program for alternative methods.

Madian Romero, technical assistant supervisor for the Caviglia-Arivaca Library, has been responsible for getting teenagers in the area to participate in the Arivaca Pollinator Pathway Project. They not only help build garden spaces around town but grow their knowledge behind the importance of pollinators, as well as community building.

"The teens, they've come up with ideas on how to fundraise for the projects," Romero emphasized. "Each business that agrees to have a garden, it can be free."

Romero added the project has also been a character-building exercise for the young people of Arivaca, and hopes it is an experience they will cherish.

The state Department of Natural Resources and Iowa State University are looking for volunteers to help create a new Bumble Bee Atlas.

Bees are an important part of the ecosystem, and scientists are figuring out their habitats to help them thrive.

Iowa is home to at least 14 species of bumble bees that help pollinate native wildflowers and flowering crops in farm fields and backyard gardens.

Iowa State University University Professor of Sustainable Agriculture and plant pathologist Matt O'Neal said the U.S. Fish and Wildlife Service recently listed several bee species as endangered.

"And that includes the Rusty Patch bumble bee," said O'Neal, "20% of what it used to be, and that includes parts of Iowa. There is also evidence that other bumble species are in decline and so, this survey will give us a chance to see where those bees are and how abundant they are."

With that information, O'Neal said scientists can work to protect the bees' habitats and create Iowa's Bumble Bee Atlas.

It's part of a larger project to map the bees and foster bee development nationwide. Sign up online to volunteer.

The national project is part of a collaboration with the Xerces Society for Invertebrate Conservation.

Some 900 people have volunteered for the national atlas project, and counted more than 20,000 bumble bees - which O'Neal said face several major threats.

"Pesticide exposure, parasite and pathogens," said O'Neal, "and then the last 'P,' and probably the most important, is poor forage."

The researchers will work to alleviate those threats by knowing where the bees are.

Volunteers have discovered species thought to be gone from their states, contributed to new field guides, and improved scientists' understanding of bumble bee populations across the country.
