Prescribed Burn in the Mariposa Grove

Yosemite National Park


Burning in the Mariposa Grove is a continuous process; the targeted areas in this burn have had 1-3 prescribed fires in the past 30 years, and continued burning is required to maintain healthy forest conditions. Fire produces the optimum conditions for giant sequoia reproduction and propagation. Fire not only removes the accumulated layers of dead woody debris exposing nutrient rich mineral soil, but dries the cones allowing the seeds to shed. In addition, fire creates holes in the forest canopy, while eliminating shade tolerate competition.
