I wonder about the area ecosystem - I think it got unbalanced after the 1906 earthquake in san francisco that caused them to (tragically) log all the redwoods.

What has grown back is groups of ~ 7 redwoods clustered around the former trunk of a felled old-growth redwood. They are more numerous and denser. I suspect with several trees competing, there will never be the thousand-year-old ecosystem again in the area.
