Evidence accumulates showing less biodiversity and functionality in restored ecosystems. Restored ecosystems have about half of the animals and plants, a third less diversity, and 40% lower cycling of C and N. Current restoration efforts do indeed recover part of the lost biodiversity and functions but fail to restore it to similar levels to what existed before degradation. Several reason can explain this pattern, among them I propose three outstanding ones: First, ecosystem restoration is narrowly oriented to simple human value-laden objectives, ignoring their complexity; second, restoration is planned at the wrong time scale, recovery of that complexity can be a centennial or millennial process; and third, restoration ignores the damage caused to the evolutionary pathways of affected communities. New approaches must be considered to move beyond failure, involving an understanding of the long-term (>100 years) assembly of interaction networks within communities and of the changes on the evolutionary potential of the recovering populations within communities.
