MOJAVE NATIONAL PRESERVE, Calif. (AP) — Firefighters aided by rain fought to contain a massive blaze that swept through the California desert into Nevada and are threatening the region’s famous spiky Joshua trees.
The York Fire that erupted last Friday is California’s largest wildfire this year. As of early Wednesday it had burned through more than 128 square miles of land and was 30% contained, fire officials said.
Humid monsoonal weather conditions Tuesday afternoon brought brief but heavy rain, especially on the south end of the fire, and kept its spread to a minimum, fire officials said. Similar conditions were expected on Wednesday, with drier weather poised to return on Thursday.
“Right now, the monsoonal influence is still over the fire,” said Marc Peebles, a spokesperson for California’s incident management team for the York Fire. “There’s always the possibility of showers that will help the effort.”
The 400 or so firefighters battling the blaze have had to balance their efforts with concerns about disrupting the fragile ecosystem in California’s Mojave National Preserve.
Crews used a “light hand on the land,” clearing and carving fire lines without the use of bulldozers in order to reduce the impact in the ecologically-sensitive region, which is home to some 200 rare plants.
“You bring a bunch of bulldozers in there, you may or may not stop the fire, but you’ll put a scar on the landscape that’ll last generations,” said Tim Chavez, an assistant chief for the California Department of Forestry and Fire Protection.
The blaze ignited near the remote Caruthers Canyon area of the vast wildland preserve, crossed the state line into Nevada on Sunday and sent smoke further east into the Las Vegas Valley.
The fire started on private lands within the preserve, but the cause remains under investigation. Less than 3% of the land in the 2,500-square mile preserve is privately owned.
While it’s one of the largest national parks outside of Alaska and Hawaii, the vast majority of the Mojave National Preserve’s 880,000 visitors last year were just passing through on their way between Southern California and Las Vegas.
The desert landscape is varied — from mountains and canyons, to sand dunes and mesas, to Joshua tree forests and volcanic cinder cones — and features about 10,000 threatened desert tortoises within its boundaries.
Some of the preserve’s plants can take centuries to recover from destruction. The pinyon-juniper woodlands alone could take roughly 200 to 300 years to return, while the blackbrush scrub and Joshua trees — which grow only in the Mojave Desert — are unlikely to regrow after this catastrophic blaze, said Ileene Anderson, a senior scientist at the Center for Biological Diversity.
The 2020 Dome Fire in a different part of the national preserve destroyed an estimated 1 million Joshua trees.
But fire itself isn’t the only worry. On federal lands, with few people and little property at risk, firefighters sometimes forgo certain equipment like bulldozers, chainsaws and aircraft.
“You don’t disturb any more soil than you absolutely have to; you don’t cut trees unless they absolutely have to come down,” said Chavez, speaking about the tactics in general.
