Last December, Santa Barbara got almost half of its average annual rainfall in the course of just one week. Much of California experienced record-breaking rainfall in 2023, and now this trend has poured into 2024. Originally dubbed an “Atmospheric River,” these warm rain storms coming from the Pacific Ocean are often caused by El Niño, a natural climate pattern that occurs every 2-7 years.

Last year’s heavy rains have repeated this year, with the lake exceeding full capacity in early February. Anglers and recreational fishers will be happy to be able to take their boats out again, but happy tidings from heavy rains aren’t always reflected everywhere. Eighteen-foot waves pounded Jalama beach in late December, flooding the nearby campground. By January 2024, floods had wreaked havoc in several other parts of Santa Barbara, knocking over trees, causing road closures along Highway 154 and leaving residential areas under feet of water.

With mudslides on steep mountainsides, trees knocking over power lines and blocking roads, and floods amongst ill-equipped infrastructure, these torrential downpours can quickly become a recipe for disaster all over California, often having the most profound effect on socially vulnerable communities.

As our climate changes, California residents may continue to see more intense extreme weather patterns over time, which could mean more flooding and downpour when we get our much-needed rain, and longer and more intense drought periods when we don’t. Both of these scenarios, drought and extreme storms, can contribute to catastrophic wildfires.

Because most of California’s rainfall typically only occurs part of the year followed by periods of drought, opportunistic plants will rapidly grow during the rainy season in Winter and Spring. This explosion of green undergrowth in California’s forests, oak savannas, and woodlands tends to dry out by late Summer. While some might think flooding and extra rain would help dampen California’s fire season, the reality is that this extra undergrowth provides ample fuel for wildfire.

To make matters more interesting, areas that are scoured by catastrophic wildfire are often more prone to floods, because the vegetation that would normally absorb rainwater burns away. This fascinating connection between fire and water may seem worrisome, but we are not powerless in the face of these growing environmental challenges.

There are many things we can do in our communities right now to bolster our resilience to floods, drought, and wildfires. Emergency preparedness and updating our infrastructure are of utmost importance, but it’s also important for us to understand that these shorter-term measures will not fix the underlying problems of climate change or environmental degradation.

Here we will focus on long-term regeneration, which means reversing the damage that’s been done to our ecosystems while simultaneously improving human communities. Here are five regenerative ways we can all take responsibility for California’s climate resilience:

1. Remove Invasives and Plant Native Perennial Grasses

Did you know that before Europeans arrived, perennial year-round grasses were dominant in California ecosystems? Many invasive annual grasses were brought by settler colonialists for cattle pasture. These invasives outcompete native plants and become fuel for wildfire and erosion, because they have short root systems that don’t retain much moisture, and they produce lots of above-ground biomass that dies once they go to seed.

Native perennial grasses support fungal communities, which exchange nutrients with trees and retain moisture. Oak trees that grow in conjunction with native grasses may therefore be more healthy and resistant to wildfire. Keeping native plants on our slopes can also help prevent mudslides.

2. Use Fire-Resistant Landscaping

Unfortunately, a lot of the drought-tolerant plants that are used for landscaping California homes are also fire magnets. For example, pine trees and certain shrubs like lavender and rosemary are prone to burn bright when a fire sweeps through. Planting native fire-resistant species will help keep properties safer from wildfires. There are many options available, but xeriscaping with rocks and succulents (drought tolerant plats with low combustablity and high water content) is one way to reduce fire risk in residential neighborhoods.

3. Harvest Rainwater and Set Up Rain Gardens

Currently, much of California’s agricultural systems and lawns are watered by draining underground aquifers. This practice puts California at greater long-term risk of wildfire and drinking water depletion. Furthermore, grass lawns only soak up a tiny bit of rainwater, becoming saturated very quickly and running off into the storm drain during the rainy season. This runoff contributes to flooding in suburban and urban areas.

One alternative is to set up rainwater harvesting systems that help rainwater to slow down, spread out, sink in, and stay in the ground. Some examples include rain gardens, swales, mulch pits, ground covers, tanks and ponds that capture rainwater and hold it for longer, rather than quickly running off into streets and spillways.

4. Reuse Greywater

Greywater is the wastewater from washing our clothes, our bodies, and our dishes. Greywater can be reused, and plants love it.

It is estimated that the average American sends more than 14,000 gallons of greywater into the sewer each year. That’s enough water to sustain a 20×20 ft flower garden for over 4 years! Greywater systems are a simple solution that would help keep the land around buildings more lush and fire-resistant during the dry season, without wasting precious potable water.

However, it is important to note that greywater systems should be installed in compliance with your local water codes, to avoid health risks and contamination. Greywater is ideally used on plants that you won’t be eating.

5. Educate and Advocate Regenerative Water & Wildfire Management Practices

These steps can be implemented without requiring access to private land, as they can be promoted through local governments and community initiatives. Achieving meaningful change, however, demands a large-scale systemic shift, especially in how municipalities and land managers handle water and wildfire management. The foundation of this shift lies in educating the public on best practices tailored to each community and ecosystem, ensuring that new policies drive the most effective outcomes.

Controlled Burns and Cultural Burns

In some cases, one way we can move forward with our wildfire policies is by looking to the past. In pre-colonial California, the lands were stewarded by many indigenous peoples that practiced seasonal “cultural burning”. Cultural burning is like a low-intensity controlled or prescribed burn, with an essential indigenous cultural tradition for cultivating food and materials. In fact, Santa Barbara was once known to have regular plumes of smoke that rose throughout the hillsides as a result of Chumash cultural burns.

Both cultural burns and controlled burns have been used all over the world and have been shown to improve soil fertility, improve soil water absorption, and reduce fire fuel loads by burning the excess dry material in the understory.

Today, major wildfires have flames that reach the crowns of trees. Before cultural burns were banned in California, these types of devastating wildfires we see today were rare. Fire suppression policies have had a major impact on California’s fire-dependent ecosystems, where many native plants rely on fire for renewal, vitality, and reproduction.

You might be thinking, “wouldn’t more burning emit more greenhouse gases?” Yes and no. Prescribed burning semi-regularly would emit carbon dioxide and other harmful gases in the short term. At the same time, it would also promote healthy soil and vegetation, thus preventing future catastrophic wildfires and sequestering more carbon in the long run.

When Controlled Burns Aren’t the Answer: Balancing Restoration with Alternative Strategies

Controlled burns can be risky, and these measures are not appropriate everywhere. Controlled burns and thinning vegetation could be very destructive practices in delicate or endangered ecosystems where disturbing the land would do more harm than good to native species. This is why it is important for people to be informed of the unique ecosystems they work in and are properly trained beforehand.

When burns aren’t possible, land managers can help prevent catastrophic wildfires by clearing and woodchipping some (not all) underbrush and fallen limbs. This approach is particularly important in areas dominated by invasive species like eucalyptus, tamarisk, and cheatgrass, which regenerate aggressively after fires, create dense fuel loads, and outcompete native vegetation. Managing these species through integrated methods—such as fuel removal and native plant restoration—can reduce wildfire intensity and support ecosystem recovery.

How Water Mismanagement Fuels California’s Fire and Flood Risks

The realm of water management in California has a long way to go, too. Building developments along major waterways and redirection of water away from natural wetlands is a recipe for future flooding. The demand for drinking water and water for agriculture is ever-growing, and allowing our underground aquifers to be over-pumped is a short-sighted solution that is permanently altering our landscapes, making California drier, more flood-prone and more fire-prone. Once aquifers are drained, they can’t be replenished.

Damming up our few remaining natural watersheds also has disastrous effects, such as wiping out our native fish populations by disrupting migration, destroying habitats, destroying carbon sinks in wetlands and oceans, depriving ecosystems of nutrients, increasing wastewater, increasing sea level, and displacing the communities that live where dams are built.

Urban Planning and Land Management for Wildfire Prevention

Effective city planning, housing codes, and land management laws are essential for preventing wildfires and reducing their impact on communities. Municipalities can implement stricter building codes that require fire-resistant materials for construction, such as non-combustible roofing and siding, and ensure proper defensible space around properties. Local governments can also encourage homeowners to maintain defensible space by clearing vegetation, dead leaves, and debris within a certain perimeter of their homes.

Zoning laws can be updated to limit the spread of developments in high-risk areas, and homeowners can be incentivized to create firebreaks or fire-resistant landscaping. Additionally, municipalities can incorporate wildfire risk assessments into development approvals and engage in proactive fire mitigation strategies, such as expanding green spaces and reducing fuel loads in urban areas.

Invasive species, industrial agriculture, climate change, prolonged fire suppression, dams, wetland draining, and aquifer overpumping have already wreaked havoc on California’s ecosystems, leading to severe economic repercussions. By embracing regenerative practices and policies, California can improve quality of life for its residents while strengthening the resilience of its ecosystems, economy, and communities for the long term. To make this shift a reality, active engagement at all levels is crucial, and there are several ways you can get involved to help drive change.
