I doubt the parks would ever let me in on a restoration, but if I were given a free hand contract to work on the grove, I would have a few workers take small picks and graze the top inch of bare earth to loosen the layer. Not within 10 feet of the trunk. But 20 feet or more away. And I would transplant-in some ferns out from the trunk.Mark Collins wrote:If the base of the tree and area around the tree was left undisturbed, how long do you think it would take for the duff area and ferns to return? Would it help to throw a few handfuls of soil or duff around the base from time to time, or cover it with fallen branches to prevent people from stepping all over it?
Otherwise, I think it would take about 20 to 100 years for for ferns to fill in naturally again. The needle duff would build up in a matter of just a few years. My estimate is based on watching the slow fill-in of decommissioned trails. They take decades to overgrow and return.
Did you ever find this page of mine? Its been online for years. It will definitely need updating because I'm sure my thoughts evolved and I'm sure I can cull some vocabulary.wisconsitom wrote:I've got to be honest here-I've often wondered too about all the ropes and other hiking apparati used to climb the big trees.
It has been read by quite a few. I know one canopy researcher paid close attention to it too.
