Faced with repeated giant fires, scientists look to make California forests more resistant
To the untrained eye, the scrubby slope off Wentworth Springs Road in the Eldorado National Forest looks like any other patch of Sierra Nevada ridgetop. Tufted in native shrubs and flecked by darkened pine stumps, it’s part of a 30,000-acre swath of land that was deforested in 2014, when the King Fire tore through 17 miles of canyon in less than six hours.
But Dana Walsh can see what’s unique. On a recent Sunday morning, the USDA Forest Service forester bent over a white flag pinned into the ground to mark a barely-visible seedling. As she points to other seemingly camouflaged baby conifers nearby, what starts to emerge is a subtle pattern she calls cluster planting.
