Good News - Near Containment of Santa Rosa Island Fire

As of Tuesday, May 26, 2026 – The wildfire on Santa Rosa Island is 97% contained !

A historic 18,837 acres were burned, making this the largest wildfire recorded across the California Channel Islands.

A huge thank you to the firefighters that fought and contained this fire. In places were firebreaks were carved out by small earth-moving equipment, efforts have been made to mitigate environmental disturbance–like the wattle rolls placed on the hillside in the above photo from US Wildfire.gov.

As the firefighting wraps up, we hope to hear from scientists on the ground about island foxes and other Santa Rosa Island species.

Santa Rosa Fire Update - Sat., May 23, 2026

As the updated incident map from U.S. Wildland Fire Service shows, the edge of the active fire has been contained to the areas of bold red line. (Click on image to go to link.) The fire is considered to be 72% containment. Firefighting aircraft have been released, though they remain available if needed. The active fire edge and hot spots will be the focus over the weekend.

Drone footage of the rare Santa Rosa Island Torrey pine grove has been made public at:

The videos provide hopeful images of pines still standing.

Information on island foxes will not be available until the firefighting effort has concluded. FIF hopes to have more information, soon.

While the active fire seems to be coming under control, this has become the largest fire documented in modern times on the California Channel Islands with 18,379 acres burned.

Update on Santa Rosa Fire and Island Foxes

 

As of Thursday, May 21, 2026:

The fire on Santa Rosa Island has now burned 17,554 acres, but is reported to be 44% contained. Specific news on wildlife and rare plants remains limited. This is what we know:

Official report from government agencies 5/21/26 on the fire (https://inciweb.wildfire.gov/incident-information/cacnp-santa-rosa-island-fire)

Highlights: Increased humidity has assisted firefighting. Today firefighters along the western fire edge are concentrating on the Cloud Forest area and working south. The fire has passed through Water Canyon, but damage to the campground was minimal. 

According the official report: "Resource Advisors continue working alongside firefighters to ensure that sensitive species and the island's cultural assets are accommodated as effectively as possible throughout firefighting operations." 

The Santa Barbara Independent reports that members of the Chumash Fire Department have joined the firefighting effort and will work with Resource Advisors on protecting Chumash cultural resources.

Containment lines are being established along Telephone Road in the area of Cherry Canyon.  

Regarding island foxes:

Like the rest of us, NPS biologists are watching the firefighting effort from the mainland. They hope to check on the status of collared foxes as soon as possible. From a small plane they will fly over the island searching for the signals of radio-collared island foxes and accessing survivorship. 

Once it is safe for biologists to return to the island, they'll be able to determine what their population wide response and capacity will be.  

Fire of this size on Santa Rosa is unprecedented since the island became part of the National Park and the full impact may not be known until island-wide island fox monitoring takes place later this summer.

When FIF has more info on specific needs for Santa Rosa Island foxes, we will post it here on islandfox.org and through our social media.

Regarding the Torrey Pines:

The fire is believed to have burned quickly through the stand of rare Santa Rosa Island Torrey pines. In 2015, approximately 10,000 pines were counted in the single grove. Fire has not accessed these trees since the National Park was established. Firefighters report that the fire burned less intensely as it came down the slope. Preliminary firefighter reports are that pines are still standing and the grove remains. The full extent of the damage, however, will not be known until ecologists and tree experts can access the island.

Fire Burning on Santa Rosa Island Impacts Island Foxes

As of 4:30 pm Tuesday, May 19, the wildfire on Santa Rosa Island continues to burn. CalFire estimates 16,938 acres have burned so far. The fire is being fought by federal fire fighters and, today, winds have decreased allowing aircraft to assist with firefighting. (CalFire is not fighting this fire, but their website is posting updates)

While the ignition of the wildfire is officially under investigation, the blaze was most likely human-caused. Early Friday morning, flames spread quickly through dry grassland vegetation.

When similar wildfire events have occurred on other Channel Islands, adult island foxes have been able to flee the fire's edge and survive. (Burnie Boots - 2007) We are hopeful that the same will be true in this case.

Unfortunately, pups born in April are currently in dens and not able to flee. In other spring-time wildfire events, pups did not survive. It is highly likely that fox pups in the fire zone will be lost.

Santa Rosa Island foxes are currently at carrying capacity for the island. The 2025 population was estimated at over 2,000 individuals. While this will most likely cause a temporary decline in the island population, island foxes and island spotted skunks have shown resilience to wildfire. Following smaller wildfire events both species have been quick to return to burned territories and able to find food resources. 

Santa Rosa is the only island were island foxes are currently monitored and studied with GPS collars. These GPS-collared individuals may provide insight into exactly how island foxes react in the face of wildfire. This data may help us understand what is important for them to survive fire events.

Our thoughts are with our National Park friends as they work to protect rare plants, like the Santa Rosa Island Torrey pine and other endemic island species, and to preserve infrastructure that enables biologists and researchers to study the island ecosystem.   

 

 

Island Foxes and the Thomas Fire

Santa Cruz Island shrouded in Thomas Fire smoke, 12/12/17

Yes, there is smoke on the water. While the Thomas Fire is burning on the mainland in Ventura and Santa Barbara Counties, smoke has blown off-shore engulfing the islands. On satellite images, Santa Cruz Island has frequently disappeared in the smoke.

While embers from the fire did reach Santa Cruz in the early days of the Thomas Fire, no fires ignited on the island. In fact, on Tuesday, Dec. 12, FIF observers reported numerous island foxes behaving normally.

This young fox in the toyon tree was foraging for toyon berries. Can you find the fox in this picture? Other island foxes were hunting on the ground beneath the toyons and redberries. Despite the smoke, island foxes were well.

We know some of the people impacted by the massive Thomas Fire are island fox friends, biologists, National Park employees, and island fox supporters. Friends of the Island Fox extends its thoughts to everyone in Ventura and Santa Barbara Counties who have lost homes and been displaced by this tragic event.

Wildfire Can Threaten Island Foxes

Responding to wildfire on the Channel Islands raises a quandary, because there are positive and negative aspects to letting wildfire burn:

• Fire is a natural element on the Channel Islands. Many native plants depend on fire to open up areas for new growth, to renew the soil, or even jump-start seeds. As omnivores, island foxes depend on diverse and healthy native plants.
• Fire can provide unexpected abundance for predatory or scavenging animals, including island foxes. Smaller animals may get caught in the fire, while birds and larger animals might escape.
• Years of drought, however, have created areas with exceptionally dry vegetation and greater than usual build-up of wildfire fuel.
• Land animals, like the island fox, and some lesser-flying birds, like the island scrub-jay, can not escape a fire burning out of control that might consume an entire island.
• Santa Cruz Island is home to endemic plants and animals that only live on that one island and nowhere else in the world. If the entire island burned, some of these species might be driven to extinction.
• The National Park is tasked with protecting historic human cultural artifacts and structures that could be destroyed.
• People visiting the island can not easily evacuate on their own; they are dependent on sea or air transportation provided by others. The National Park must always consider visitor and staff safety.

Island scrub-jays only live on Santa Cruz Island

When lightning struck Santa Cruz Island during the night of Sept. 10th or early morning of Sept. 11th, all of these factors (and more) had to quickly be taken into account by officials at Channel Islands National Park.

2007 Catalina Island Fire

'Burnie Boots' - Catalina 2007

In 2007, fire raged up canyons and across hillsides on Santa Catalina Island. While only one female island fox was known to be injured in the fire, biologists later discovered that numerous island fox pups were lost to the flames because the fire occurred in spring and many pups were still too young to leave the dens where they were born. Catalina Island Conservancy biologists believe the injured female island fox risked her own life, walking across burning coals, to try and return to her pups in the den.

Wildfire is unpredictable, and in this incidence, the negative threats outweighed the potential positives. U.S. Forestry Service smoke jumpers were called in and they parachuted down to the island to put out the fire.

The wildfire was first spotted by a concerned citizen on a boat. Threats to island foxes and the Channel Islands can come in many different forms. Some like disease from domestic dogs or introduced wildlife are similar to lightning, they may initially strike in one place, but the consequences can quickly spread across an entire island. Island foxes need all of us to be as vigilant as the boater who reported the wildfire - one person can make a difference.
