A windowless warehouse on the outskirts of Davis shelters pieces of California’s forests. …“This is like the mothership of forestry in California right here,” said Stewart McMorrow, staff chief for wildfire resilience at Cal Fire, standing outside the heavy metal door of the state seed bank at Cal Fire’s Lewis A. Moran Reforestation Center in Davis. Private landowners especially rely on these seeds — some now more than a half-century old — to reforest property destroyed by wildfire. At the pace California is burning, it’s nowhere near enough. Climate change and more than a century of overzealous fire suppression are now fueling wildfires so severe that they’re wiping out the very forests that need fire to thrive — leaving iconic landscapes at risk of turning into brush and scrub, permanently. Over the past quarter century, high-severity wildfires have burned 2.3 million acres of California’s forestland so completely that the trees are unlikely to return on their own.
