Damage from the 2009 Lost Horse Mine fire at Joshua Tree National Park. No cause was ever determined for this fire, which destroyed 450 acres (180 ha) of delicate desert habitat. It will likely be decades before the hopsages and yuccas that cover the lower slopes re-establish on the upper hillside. Because of the sensitivity of the habitat Joshua Tree National Park observes a mandate to suppress all fires whenever practicable.
