+ | Landscape degeneration is a phenomenon at planetary scale. Some see this century as the age of ecological regeneration; | ||
+ | \\ | ||
+ | This lab brings together field-workers and field-thinkers from the environmental ‘avant-garde’ who work at the level of community, technology data to design and develop actual applications of autonomous agents in regenerative ecological practice. | ||

- | == Second phase techniques: == | + | |
- | - structural complexity enhancement (jump towards late-successional diversity) knock over some of the trees and expose roots, strip bark from some of the trees to create snags (standing dead trees) breaking up canopy cover, or somehow bring in heavy longs from elsewhere > out: creates habitat for insects, birds, mammals, amphibians that mitigate disease, pests and renewed space for pioneering vegetation and the associated wildlife | + | |
- | - atmospheric water cycle: canopy cover starts to work as an atmospheric moisture pump (near coast or on mountain side) | + | |
