In case you’re type of judgmental on the subject of vegetation, you would possibly describe the chamise plant as “meh.” Technically it’s a shrub, which within the hierarchy of plant varieties barely outranks a weed. Chamise grows as much as a dozen ft tall and sprouts needle-like leaves lower than a half-inch lengthy, making it seem like overgrown rosemary. Solely it doesn’t actually scent, despite the fact that it’s a member of the rose household.

Appearances and smells apart, chamise seems to be an enchanting plant, one important not solely to the California panorama however to the protection of its human residents. When hearth scientists wish to know the way flammable the state’s vegetation could be, they don’t depend on some newfangled gadget. They depend on chamise. “It is a actually fairly and type of understated shrub,” says Bryant Baker, conservation director of the Los Padres ForestWatch, which advocates for the safety of California’s habitats. “And I feel as a result of it is so widespread, it is usually taken without any consideration.”

However Californians ignore it at their peril, as a result of it is a wonderful indicator of how dry the entire panorama is getting. Chamise dominates native chaparral ecosystems up and down the state, dense shrublands which might be too arid for bushes. (This can be a Mediterranean local weather, in spite of everything, during which rain stops within the spring and doesn’t restart till autumn.) However the chamise is fantastically tailored to journey out the baking warmth: these tiny, leathery leaves have far much less floor space than a broadleaf, so that they don’t lose as a lot moisture. “These vegetation are tailored to go for a lot of months with no single drop of water, which is fairly wonderful,” says Baker. “You do not often discover that outdoors of desert areas.”
