Will Climate Change Claim the Redwoods?

Northern California’s iconic redwood groves are facing tough growing conditions in a warming world, writes Sierra magazine: “With diminishing snowpack in the Sierra and decreasing fog along the coast, redwoods face a hostile future and a worst-case scenario that could result in more Sequoioideae museums than functioning forests.”

To study the sequoias more closely, Sierra reports, tree scientists are ascending into the canopy using mountaineering gear, then counting cones, taking core samples, measuring branches and otherwise inspecting trees like doctors doing a full physical. They then create computerized, highly detailed 3-D simulations of each tree.

Eventually they hope this data will help craft strategies for survival, but they’re also learning a lot as they go. One of the most fascinating recent findings involves the amazing productivity of old giants. Writes Sierra:

Green groups including the Sierra Club, the publisher of Sierra, have repeatedly challenged the U.S. Forest Service’s management plans for the redwoods at Giant Sequoia National Monument, arguing that controlled fires, not logging, will help the redwood forests thrive, since they use fires to procreate.

As for the prospecting of decreasing fog in an area renowned for its misty beauty, Northern California’s Terrain last year delved into this topic and emerged with inconclusive predictions from fog researchers. For if ancient trees do not easily give up their secrets, the fog withholds even more:
