The national park had been trying to conserve the species wherever in the park it was found. The future risk of extirpation prompted adaptation of conservation efforts to focus on protecting potential refugia, where suitable conditions may persist for the species into the future . The national park used spatial analyses of suitable climate to identify potential refugia under all emissions scenarios, except for the highest . The park prioritises the refugia for removal of invasive grasses and fire control  and works to restore refugia that have burned in fires, using native plants, including nursery-grown Joshua tree seedlings. The park and its partners are monitoring plant species composition and abundance in the refugia for early warnings of any changes .
