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.

Earth Day is celebrated annually on April 22nd, and it serves as a reminder of the importance of taking care of our planet. It’s a day to reflect on our impact on the environment and to take action to create a better future for our planet.

The first Earth Day was celebrated in 1970, and it marked the beginning of the environmental movement. Since then, Earth Day has grown into an international event, with millions of people around the world participating in activities and events to raise awareness about environmental issues.

One of the main goals of Earth Day is to encourage people to take action to reduce their impact on the environment. This can include simple actions like recycling, conserving energy, and reducing waste. It can also involve more significant actions like advocating for environmental policies and supporting sustainable businesses.

Another important aspect of Earth Day is education. It’s a time to learn about environmental issues and to understand how our actions can impact the planet. Many schools and organizations use Earth Day as an opportunity to teach children about the importance of taking care of the environment.

This year’s Earth Day theme is “Restore Our Earth”, and it focuses on the idea that we can all play a role in restoring the planet’s ecosystems. This can include actions like planting trees, reducing plastic waste, and supporting sustainable agriculture.

Earth Day is an important reminder of the impact that we have on the environment and the importance of taking action to create a better future for our planet. By working together and taking small steps, we can make a big difference in protecting the planet and ensuring that it remains healthy and beautiful for generations to come.

Mosquitoes carrying malaria are evolving more quickly than insecticides can kill them – researchers pinpoint how

The fight against infectious disease is a race against evolution. Bacteria become resistant to antibiotics. Viruses adapt to spread more quickly. Diseases transmitted by insects present another evolutionary front: Insects themselves can evolve resistance to the poisons that people use to kill them.

In particular, the mosquito-borne disease malaria kills over 600,000 people annually. Since World War II, people have battled malaria with insecticides – chemical weapons intended to kill Anopheles mosquitoes infected with the Plasmodium parasites that cause the disease.

However, mosquitoes are quickly evolving counterstrategies that make these insecticides ineffective, putting millions of people at greater risk of deadly infection. My colleagues and I have newly published research showing how.

Insecticide resistance threatens public health

As an evolutionary geneticist, I study natural selection – the basis for adaptive evolution. Genetic variants that best promote survival can replace less advantageous versions, causing species to change. Anopheles mosquitoes are frustratingly adept at evolving.

In the mid-1990s, most African Anopheles were susceptible to pyrethroids, a popular type of insecticide originally derived from chrysanthemums. Anopheles control relies on two pyrethroid-based methods: insecticide-treated bed nets to protect sleepers, and indoor residual spraying of insecticide against the walls of homes. These two methods alone likely prevented over a half-billion cases of malaria between 2000 and 2015.

However, mosquitoes today from Ghana to Malawi are often able to survive insecticide concentrations 10 times the previously lethal dose. Along with Anopheles control efforts, agriculture also inadvertently exposes mosquitoes to pyrethroids and contributes to insecticide resistance.

In some African locales, Anopheles is already showing resistance to all four main classes of insecticide used for malaria control.

Adaptation in Latin American mosquitoes

Anopheles mosquitoes and the malaria-causing Plasmodium also occur outside Africa, where insecticide resistance is less well-researched.

In much of South America, the main malaria vector is Anopheles darlingi. This mosquito species has diverged evolutionarily from the African vectors so extensively that it might be a different genus, Nyssorhynchus. Along with colleagues from eight countries, I analyzed over 1,000 Anopheles darlingi genomes to understand its genetic diversity, including any recent changes due to human activity. My collaborators collected these mosquitoes at 16 locations ranging from the Atlantic coast of Brazil to the Pacific side of the Andes in Colombia.

We found that, like its African counterparts, Anopheles darlingi shows extremely high genetic diversity – more than 20 times that of humans – indicating that very large populations of this insect exist. A species with such a vast gene pool is well poised to adapt to new challenges. The right mutation giving it the advantage it needs is more likely to pop up when there are so many individuals. And once that mutation starts to spread, it’s protected by numbers since it won’t be wiped out if a few mosquitoes die by chance.

In contrast, bald eagles in the contiguous U.S. were never able to evolve resistance against the insecticide DDT and approached extinction. Evolution is more efficient among millions of insects than mere thousands of birds. And indeed, we saw signals of adaptive evolution in the resistance-related genes of Anopheles darlingi occurring over the past few decades.

Mosquitoes evolve to detoxify poisons

Insecticides like pyrethroids and DDT share the same molecular target: channels in nerve cells that can open and close. When open, the nerve cell stimulates other cells. These insecticides force the channels to remain open and continuously fire, causing paralysis and death. However, insects can evolve resistance by changing the shape of the channel itself.

Earlier genetic scans performed by other researchers had not detected this type of resistance in Anopheles darlingi, and neither did ours. Instead, we found that resistance is evolving in another way: a group of genes encoding enzymes that break down toxic compounds. High activity of these enzymes, called P450, frequently underlies resistance to insecticides in other mosquitoes. The same cluster of P450 genes has changed independently at least seven times across South America since insecticide use began in the mid-20th century.

In French Guiana, a different set of P450 genes exhibits a similar evolutionary pattern, cementing the clear connection between these enzymes and adaptation. Moreover, when we exposed mosquitoes to pyrethroids in sealed bottles, differences among the P450 genes of individual mosquitoes were linked to the length of time they stayed alive.

Insecticide-heavy campaigns against malaria have been only sporadic in South America and may not be the main driver behind this evolution. Instead, it’s possible that mosquitoes are being exposed indirectly to agricultural insecticides. Intriguingly, we saw the strongest signs of evolution in places where farming is prevalent.

Toward more sophisticated vector control

Despite new vaccines and other recent advances against malaria, mosquito control remains essential for reducing disease.

Some countries are launching trials of gene drives to control malaria, which involve forcing a genetic modification into a mosquito population to reduce their numbers or their tolerance for Plasmodium. Such prospects are exciting, though the relentless adaptability of mosquitoes could be an obstacle.

I and others are revising methods to efficiently test for emerging insecticide resistance. Genome-scale sequencing remains important to detect new or unexpected evolutionary responses. The risk of adaptation is highest under a continuous, strong selection pressure, so minimizing, switching and staggering pesticides can help thwart resistance.

Success in the fight against evolving resistance will require a coordinated effort of monitoring, and reacting accordingly. Unlike evolution, humans can think ahead.

Simple Ways to Make At-Home Recycling More Effective

(Feature Impact) Recycling is a simple way households can reduce waste and help protect natural resources. While many communities offer curbside recycling programs, some people still wonder if they’re doing it correctly or if they’re missing opportunities to recycle more.

To create a more eco-friendly household, consider these practical tips to help you reduce waste, stay organized and make recycling part of your everyday routine.

Know What Your Local Program Accepts

Recycling rules vary depending on your city or waste management provider. Most curbside programs include items like cardboard, paper, aluminum cans and plastics, but others – such as glass – may require drop-off recycling. Review your community guidelines so recyclables don’t accidentally end up in the regular trash.

Create a Simple Sorting System

Set up clearly labeled bins – separated for paper, plastics and metals – in a high-traffic area like the kitchen, garage or laundry room.

Rinse Before You Recycle

Food residue can contaminate other recyclables and may cause entire batches of materials to be rejected during the recycling process. Quickly rinsing yogurt cups, jars or soup cans of leftover residue helps keep recycling streams clean and more likely to be processed properly.

Break Down Boxes

Cardboard boxes are among the most commonly recycled household materials. Flattening boxes before placing them in the recycling bin saves space and allows collection trucks to hold more.

Compost Food Scraps

Not everything belongs in the recycling bin, particularly food waste. Composting fruit peels, vegetable scraps, coffee grounds and eggshells is an easy way to reduce the amount of trash your household produces. Finished compost can be used in gardens, flower beds or houseplants, turning kitchen waste into a valuable resource.
