The Ten Principles of Ecological Restoration...
Re-establish ecological linkages, reconnecting the
threads in the web of life
An ecosystem is a community of interdependent species,
all of which are necessary for the health and proper functioning of
the system. When ecosystems become degraded and fragmented, they become
less self sustaining and vulnerable to catastrophic events such as tornadoes
and disease. The dispersal of plants and animals is cut off. Species
that require large areas are extirpated and a habitat is unable to respond
with an influx of replacement species. Urban natural habitats, such
as parks, have much in common with islands. Only a few wide ranging
generalist species can make the voyage across inhospitable spaces to
re-colonize. Non-native species often fill this role in degraded urban
habitats. Restoring corridors for the exchange of species and long term
biological sustainability is crucial for a self-maintaining system.
