As promised, I went up to restoration area to see how well the ground beneath the trees is faring moisture wise. Here are all the photos.
Well, there wasn't much fog drip to begin with, so no big surprise here.
Most of it evaporated here as well.
Or maybe not. Here is clear evidence that the ground is still moist from the fog drip from the coast live oak canopy above.
The ground under the redwoods would still be moist of course. These future giants produced enough fog drip to saturate the ground and create a little surface runoff.
Redwood fog drip can penetrate the ground up to 35cm.
