On the south-eastern corner of Santa Rosa Island lies a grove of a few thousand Torrey pine trees, some of them more than 250 years old. The only other place on earth where these gnarled pines exist is in San Diego county, but biologists classify the two groves as different subspecies. So when a rare wildfire broke out on Santa Rosa Island late last week, firefighters raced to keep it from spreading into the grove, where it threatened to consign the island’s Torrey pines to extinction.
So far, they appear to be succeeding – even as the 18,000-acre fire has torched nearly one-third of the island’s surface. But biologists who have studied Santa Rosa Island’s unique ecology are watching anxiously as the fire continues to burn a part of the island that is home to six plants found nowhere else on the planet.
