What Native-held lands in California can teach about resilience and the future of wildfire

It took decades, stacks of legal paperwork and countless phone calls, but, in the spring of 2025, a California Chuckchansi Native American woman and her daughter walked onto a 5-acre parcel of land, shaded by oaks and pines, for the first time.

This land near the foothills of the Sierra National Forest is part of an unusual category of land that has been largely left alone for more than a century. The parcel, like roughly 400 other parcels across the state totaling 16,000 acres in area, is held in trust by the federal government for the benefit of specific Indigenous people – such as a family member of the woman visiting the land with her daughter.

Largely inaccessible for more than a century, and therefore so far of little actual benefit to those it is meant for, this land provides an opportunity for Indigenous people to not only have recognized land rights but also to care for their land in traditional ways that could help reduce the threat of intensifying wildfires as part of a changing climate.

In collaboration with families who have long been connected to this land, our research team at the University of California, Davis is working to clarify ownership records, document ecological conditions and share information to help allottees access and use their allotments.

California’s unique historical situation

As European nations colonized the area that became the United States, they entered into treaties with Native nations. These treaties established tribal reservations and secured some Indigenous rights to resources and land.

Just after California became a state in 1850, the federal government negotiated 18 treaties with 134 tribes, reserving about 7.5 million acres, roughly 7.5% of the state, for tribes’ exclusive use.

However, land speculators and early state politicians considered the land too valuable to give away, so the U.S. Senate refused to ratify the treaties – while allowing the tribes to think they were valid and legally binding. As a result, most California Native Americans were left landless and subject to violent, state-sanctioned removals by incoming miners and settlers.

Then, in 1887, Congress passed the Dawes Act, which allowed Native people across the U.S. to be assigned or apply for land individually. Though it called the seized land – their former tribal homelands – the “public domain,” the Dawes Act presented a significant opportunity for the landless Native people in California to secure land rights that would be recognized by the government.

These land parcels, called allotments, are not private land, public land or reservation land – rather, they are individual parcels held in trust by the federal government for the benefit of allottees and their descendants.

Many of these allotments were remote – ecologically rich, yet hard to access. They were carved out of ancestral territories but often lacked access to infrastructure like roads, water or electricity. In some cases, allotments were separated from traditional village sites, ceremonial areas or vital water resources, cutting them off from broader ecosystems and community networks.

Federal officials often drew rough or incorrect maps and even lost track of which parcels had been allotted and to whom, especially as original allottees passed away. As a result, many allotments were claimed and occupied by others, coming into private hands without the full knowledge or consent of the Native families they were held in trust for.

There were once 2,522 public domain allotments in California totaling 336,409 acres. In 2025, approximately 400 of these allotments remain, encompassing just over 16,000 acres. They are some of the only remaining, legally recognized tracts of land where California Native American families can maintain ties to place, which make them uniquely significant for cultural survival, sovereignty and ecological stewardship.

The allotments today

Because of their remoteness, many of these lands remained relatively undisturbed by human activity and are home to diverse habitats, native plants and traditional gathering places. And because they are held in trust for Native people, they present an opportunity to exercise Indigenous practices of land and resource management, which have sustained people and ecosystems through millennia of climate shifts.

We and our UC Davis research team partner with allottee families; legal advocates including California Indian Legal Services, a Native-led legal nonprofit; and California Public Domain Allottee Association, an allottee-led nonprofit that supports allottees to access and care for their lands. Together, we are studying various aspects of the remaining allotments, including seeking to understand how vulnerable they are to wildfire and drought, and identifying options for managing the land to reduce those vulnerabilities.

An opportunity for learning

So far, our surveys of the vegetation on these lands suggest that they could serve as places that sustain both flora and fauna as the climate changes.

Many of these parcels are located in remote, less-developed foothills or steep terrain where they have remained relatively intact, retaining more native species and diverse habitats than surrounding lands. Many of these parcels have elements like oak woodlands, meadows, brooks and rivers that create cooler, wetter areas that help plants and animals endure wildfires or periods of extreme heat or drought.

Allotment lands also offer the potential for the return of stewardship methods that – before European colonization – sustained and improved these lands for generations. For example, Indigenous communities have long used fire to tend plants, reduce overgrowth, restore water tables and generally keep ecosystems healthy.

Guided by Indigenous knowledge and rooted in the specific cultures and ecologies of place, this practice, often called cultural burning, reduces dry materials that could fuel future wildfires, making landscapes more fire-resilient and lowering both ecological and economic damage when wildfires occur. At the same time, it brings back plants for food, medicine, fiber and basketry for California Native communities.

Challenges on allotments

The Chuckchansi family who reached their land for the first time in the spring of 2025 would like to move onto the land. However, the parcel is surrounded by private property, and they need to seek permission from neighboring landowners to even walk onto their own parcel.

In addition, a small number of employees at the Bureau of Indian Affairs are responsible for allotments, and they must also deal with issues on larger reservations and other tribal lands.

Further, because the lands are held in federal trust, allottees’ ability to engage in traditional management practices like cultural burning often face more stringent federal permitting processes than state or private landowners – including restrictions under the Clean Air Act and the National Environmental Policy Act.

To our knowledge, no fire management plans have been approved by the Bureau of Indian Affairs on California Native American public domain allotments. Nonetheless, many families are interested in following traditional practices to manage their land. These efforts were a key topic at the most recent California Public Domain Allottees Conference, which included about 100 participants, including many allottee families.

Why it matters

As California searches for ideas to help its people adapt to climate change, the allotment lands offer what we believe is a meaningful opportunity to elevate Indigenous leadership in climate adaptation. Indigenous land stewardship strategies have shown they can reduce wildfire risk, restoring ecosystems and sustaining culturally important plants and foods. Though the parcels are small, the practices applied there – such as cultural burning, selective gathering and water stewardship – are often low-cost, community-based and potentially adaptable to larger parcels elsewhere around the state.

One option could be to shift some of the regulatory authority from the Bureau of Indian Affairs to the allottees themselves. Shifting authority to Indigenous peoples has improved forest health elsewhere, as found in a collaborative study between University of California Extension foresters and Hoopa Tribal Forestry. That research found that when the Hoopa Tribe gained control of forestry on their reservation along the Trinity River in northern California, tribal leaders moved toward more restorative forestry practices. They decreased allowable logging amounts, created buffers around streams and protected species that were culturally important, while still reducing the buildup of downed or dead wood that can fuel wildfires.

At a time when California faces record-breaking wildfires and intensifying climate extremes, allotments offer rare pockets of intact habitat with the potential to be managed with cultural knowledge and ecological care. They show that adapting to change is not just about infrastructure or technology, but also about relationships – between people and place, culture and ecology, past and future.

After the January 2025 Moss Landing battery storage fire, researchers found nickel, manganese and cobalt particles raining onto nearby wetlands. A new study shows how toxic metals settled, spread with tides and rain, and may bioaccumulate through Elkhorn Slough’s food web—raising fresh questions about battery storage safety.

Moss Landing Battery Fire Fallout: Study Finds Toxic Metals Captured in Nearby Wetlands

Ivano W. Aiello, San José State University When fire broke out at the world’s largest battery energy storage facility in January 2025, its thick smoke blanketed surrounding wetlands, farms and nearby communities on the central California coast. Highways closed, residents evacuated and firefighters could do little but watch as debris and ash rained down. People living in the area reported headaches and respiratory problems, and some pets and livestock fell ill. Two days later, officials announced that the air quality met federal safety standards. But the initial all-clear decision missed something important – heavy metal fallout on the ground.

When battery energy storage facilities burn, the makeup of the chemical fallout can be a mystery for surrounding communities. Yet, these batteries often contain metals that are toxic to humans and wildlife. The smoke plume from the fire in Vistra’s battery energy storage facility at Moss Landing released not just hazardous gases such as hydrogen fluoride but also soot and charred fragments of burned batteries that landed for miles around. I am a marine geologist who has been tracking soil changes in marshes adjacent to the Vistra facility for over a decade as part of a wetland-restoration project. In a new study published in the journal Scientific Reports, my colleagues and I were able to show through detailed before-and-after samples from the marshes what was in the battery fire’s debris and what happened to the heavy metals. The batteries’ metal fragments, often too tiny to see with the naked eye, didn’t disappear. They continue to be remobilized in the environment today.

What’s inside the batteries

Moss Landing, at the edge of Monterey Bay, has long been shaped by industry – a mix of power generation and intensive agriculture on the edge of a delicate coastal ecosystem. The Vistra battery storage facility rose on the site of an old Duke Energy and PG&E gas power plant, which was once filled with turbines and oil tanks. When Vistra announced it was converting the site into the world’s largest lithium-ion battery facility, the plan was hailed as a clean energy milestone. Phase 1 alone housed batteries with 300 megawatts of capacity, enough to power about 225,000 homes for four hours. The energy in rechargeable batteries comes from the flow of electrons released by lithium atoms in the anode moving toward the cathode. In the type of batteries at the Moss Landing facility, the cathode was rich in three metals: nickel, manganese and cobalt. These batteries are prized for their high energy density and relatively low cost, but they are also prone to thermal runaway. Lab experiments have shown that burning batteries can eject metal particles like confetti.

Metals found in wetlands matched batteries

When my team and I returned to the marsh three days after the fire, ash and burned debris covered the ground. Weeks afterward, charred fragments still clung to the vegetation. Our measurements with portable X-ray fluorescence showed sharp increases in nickel, manganese and cobalt compared with data from before the fire. As soon as we saw the numbers, we alerted officials in four counties about the risk. We estimate that about 25 metric tons (55,000 pounds) of heavy metals were deposited across roughly half a square mile (1.2 square kilometers) of wetland around Elkorn Slough, and that was only part of the area that saw fallout. To put this in perspective, the part of the Vistra battery facility that burned was hosting 300 megawatts of batteries, which equates to roughly 1,900 metric tons of cathode material. Estimates of the amount of batteries that burned range from 55% to 80%. Based on those estimates, roughly 1,000 to 1,400 metric tons of cathode material could have been carried into the smoke plume. What we found in the marsh represents about 2% of what may have been released.

These contour maps show how metals from the Moss Landing battery fire settled across nearby wetlands. Each color represents how much of a metal – nickel, manganese or cobalt – was found in surface soils. Darker colors mean higher concentrations. The highest levels were measured about two weeks after the fire, then declined as rain and tides dispersed the deposits. Charlie Endris
We took samples at hundreds of locations and examined millimeter-thin soil slices with a scanning electron microscope. Those slices revealed metallic particles smaller than one-tenth the width of a human hair – small enough to travel long distances and lodge deep in the lungs. The ratio of nickel to cobalt in these particles matched that of nickel, manganese and cobalt battery cathodes, clearly linking the contamination to the fire. Over the following months, we found that surface concentrations of the metals dropped sharply after major rain and tidal events, but the metals did not disappear. They were remobilized. Some migrated to the main channel of the estuary and may have been flushed out into the ocean. Some of the metals that settled in the estuary could enter the food chain in this wildlife hot spot, often populated with sea otters, harbor seals, pelicans and herons.

Making battery storage safer as it expands

The fire at Moss Landing and its fallout hold lessons for other communities, first responders and the design of future lithium-ion battery systems, which are proliferating as utilities seek to balance renewable power and demand peaks. When fires break out, emergency responders need to know what they’re dealing with. A California law passed after the fire helps address this by requiring strengthening containment and monitoring at large battery installations and meetings with local fire officials before new facilities open.
How lithium-ion batteries work, and why they can be prone to thermal runaway.
Newer lithium-ion batteries that use iron phosphate cathodes are also considered safer from fire risk. These are becoming more common for utility-scale energy storage than batteries with nickel, manganese and cobalt, though they store less energy. How soil is tested is also important. At Moss Landing, some of the government’s sampling turned up low concentrations of the metals, likely because the samples came from broad, mixed layers that diluted the concentration of metals rather than the thin surface deposits where contaminants settled.

Continuing risks to marine life

Metals from the Moss Landing battery fire still linger in the region’s sediments and food webs. These metals bioaccumulate, building up through the food chain: The metals in marsh soils can be taken up by worms and small invertebrates, which are eaten by fish, crabs or shorebirds, and eventually by top predators such as sea otters or harbor seals. Our research group is now tracking the bioaccumulation in Elkhorn Slough’s shellfish, crabs and fish. Because uptake varies among species and seasons, the effect of the metals on ecosystems will take months or years to emerge. Ivano W.

Severe weather can produce dramatic sights—but not every spinning column of air is a tornado.

A [gustnado](chatgpt://generic-entity?number=0) is a brief, ground-level swirl of rotating air that forms along a thunderstorm’s gust front. Gustnadoes often appear suddenly, kicking up dust or debris, which can make them look more dangerous than they actually are.

Unlike tornadoes, gustnadoes do not connect to a storm’s rotating updraft. Because of this, they are usually weaker, short-lived, and difficult to detect on weather radar.

Gustnadoes typically last only seconds to a few minutes and are most commonly spotted in dry regions, where loose soil makes their rotation visible.

The takeaway: If it’s spinning near the ground ahead of a storm, it may look intense—but it’s not always a tornado.

How China cleaned up its air pollution – and what that meant for the climate

How China cleaned up its air pollution: Beijing’s air quality went from hazardous to good while Delhi and Lahore still struggle. Discover how China dramatically reduced pollution since 2013—and why cleaner air may have unintended consequences for global warming and climate change.

How China cleaned up its air pollution – and what that meant for the climate

Gemma Ware, The Conversation
Delhi: 442. Lahore: 334. Beijing: 16. These are the levels of PM 2.5, one of the principle measures for air pollution, on November 19. As Pakistanis and Indians struggle with hazardous air quality, in Beijing – a city once notorious for its smog – the air quality is currently rated as good. Ahead of the 2008 Beijing Olympics, the Chinese government was so concerned about pollution that it introduced temporary restrictions on cars, shut down factories and stopped work on some construction sites. The measures worked and one study later found that levels of air pollution were down 30% during the period when the temporary Olympic restrictions were in place. It would take a few more years before the Chinese government implemented a clean air action plan in 2013. Since then, China has achieved a dramatic improvement in its air quality. In this episode of The Conversation Weekly podcast, we speak to Laura Wilcox, a professor at the National Centre for Atmospheric Science at the University of Reading in the UK, to understand how China managed to clean up its air pollution. But Wilcox’s recent research uncovered some unintended consequences from this cleaner air for the global climate: the pollution was actually helping to cool the atmosphere and by taking it away, it may have accelerated global warming. Wilcox explains:
 What we’re seeing is a removing of cooling that’s revealing warming that’s already there. So the air pollution isn’t the cause of the warming. It’s just letting us see stuff that we’ve already done.
