It seems to me to be a one way downhill process ?

A bare volcanic rock after its eruption 600 years ago, the island is now largely reforested. Lava fields contain no soil of the typical kind, so it must come from windblown matter and slow breaking-down processes of the native flora.
A lot of loss can also be trivially reduces by planting rows of trees between fields, which I saw all over the place in NZ, but haven’t seen elsewhere.
