The Ten Principles of Ecological Restoration...
Work outward from areas of strength, where the ecosystem
is closest to its natural condition
For ecological restoration to be most effective,
it should begin in and spread outward from sites where the ecosystem
is most intact and shows the greatest diversity. Under natural conditions
the ecosystem would expand from such locations under its own direction.
Working outward from intact remnants facilitates the dispersal of insects,
animals and plants into the restoration area and minimizes the amount
of human intervention.
