Santa Rosa Island Fire Nears Full Containment as Scientists Prepare Recovery Assessment

Even as firefighters inch closer toward full containment of the devastating Santa Rosa Island Fire, scientists and officials continue to assess the damage caused by the blaze. The fire has burned 18,379 acres and has been 97% contained, according to CAL Fire’s update on May 28.

In a social media post, the Channel Island National Park Foundation said that the focus will now pivot to recovery. Crews from the National Park Service have been working with firefighters to fully contain the blaze, stabilize the landscape, and protect sensitive areas, the foundation said.

In the following few weeks, the Burned Area Response team, a team of specialized scientists, will arrive to assess the damage and identify the required recovery efforts. The team will write a report with recommendations on how to keep the public safe, preserve the island’s historical and cultural resources, and protect the island’s environment.

“Santa Rosa Island is different – unlike mainland California, the island’s ecosystem didn’t evolve with fire and isn’t adapted to bounce back from it naturally,” the foundation wrote on Instagram. The team’s guidance will also assist federal land managers in protecting lives and supporting Santa Rosa Island’s recovery as quickly as possible.

While CAL Fire stated that the fire was human-caused, the fire could have been started by a stranded sailor who set off distress flares while trying to signal SOS, according to a CBS News report. Although the fire is nearly fully contained, it has charred almost one-third of the island.

The fire is the largest ever wildfire to be recorded on any of the Channel Islands. Satellite images released by NASA show vast blackened sections, documenting the spread of the fire and the resulting destruction.

Part of the Channel Islands National Park, Santa Rosa Island is often referred to as the “Galapagos of North America” because of its unparalleled biodiversity. The island is home to several rare and endemic species that are not found anywhere else on Earth, including plant species and the rare Torrey Pine population.

While small pockets of the Torrey Pines burned with higher intensity, the overall pine population still exists and remains mostly intact, authorities confirmed on May 20. Beyond the immediate burn scar, officials are trying to understand how the ecologically significant islands will recover from a wildfire of this massive size.

NASA’s imagery is a reminder that even after flames die down, the effects of a major wildfire can linger for years, especially in ecosystems where fire has historically been rare.
