California’s largest wildfire of the year threatens fragile desert ecosystem

The York fire has burned pinyon pines, junipers and the region's famous Joshua trees, which are particularly vulnerable to wildfires

The hundreds of firefighters battling California's largest wildfire this year in the Mojave national preserve have to work strategically to avoid disrupting a fragile ecosystem.

The York fire, which erupted last Friday, has burned through more than 125 sq miles (323.7 sq km) across the California desert toward the Nevada border.
