With owners of a cabin in Wilsonia, I went to look at the area of Grant Grove around the North Grove Loop, to see how it's doing after the fire that went through there a few years ago.
There are still thousands of new sequoia seedlings a foot or two high in places. Natural selection will undoubtedly pare those down to just a few winners; however, it's encouraging to see solid new growth surviving under the completely open, foliage-free canopy areas up there.
Some of the mature sequoias looked intact enough to have survived the fire, but they don’t seem to be responding with much visible new growth. They might have died, having been damaged irreparably from heat stroke during the sustained burn. I hope not, but we'll have to see.
