Can revegetation assist in the conservation of biodiversity in agricultural areas?

Revegetation can either provide buffer strips around existing habitat remnants to protect them from external impacts, corridors between them to increase connectivity, or additional habitat to increase the area of vegetation available, or can enhance degraded remnant areas. Revegetation will also help retain biodiversity indirectly if it helps stabliize an otherwise degrading agricultural landscape. Revegetation in agricultural areas is compared with minesite rehabilitation, where the redevelopment of functioning ecosystems and faunal habitat appears to be possible. The task is harder in the agricultural situation because the scale of modification is greater, soil changes are more difficult to redress, and recolonization by native species is less likely. -from Author
