Peat forms at about 1mm per year, so it's going to take a long time for those metres to be rebuilt at 1000 yrs per metre. Regardless of which when it's disturbed in the first place the carbon stored has gone.
It doesn't regen on it's own, it needs human intervention. There is some ruined near me, there was a moor fire years ago and it's never recovered, it's just being eroded and washed away.
It's not so much bird strikes, but the fact that they just stay away from the area.
Firstly the important stuff to biodiversity isn't in the layers of peat below..... Peat is literally acidic death.... Hence why it's such a good carbon store. Things that don't degrade are devoid mostly of microbes... Or life in general. Particularly deep peat.... Bog butter/bodies... Etc.
The stuff on top is however important.... Mosses and other plants. However plants want to grow if you create there niche.... We wouldn't be pumping millions into quite successful rewetting projects if they didn't work.... They do, and most sites that have been restored are monitored and are adding peat.
On the sidenote FYI/Personal opinion. I'm actually convinced at the argument peat should be classed itself as a renewable at the local level. Particularly in Ireland where tractor mounted slit cutters are used, but that's something no one will ever prove or stand by. Commercial extraction is a negative thing in most cases.
Back to your wind turbines.... It's not economical for a energy company to dig through deep peat. In most cases it'll be equivalent to stripping topsoil.... Which actually has a similar affect on releasing carbon. You can actually see in the photo you choose to use the soil colours around the excavation site.
We would not be restoring peatlands if they did not regenerate..... And if they didn't regenerate we would probably never have them in the first place. It is true they require the correct hydrology but that's not hard to achieve..... Go get a bath tub, put some water in it and launch some sporagum (still can't spell it) moss and a couple floating bits of wood in and leave..... It'll develop and in a decade or two you'll have enough peat for a bath
