How Can Ecosystems Be Restored?


Some general guidelines for restoring an ecosystem:

• Assess the site.

— What are the current conditions of the site?

— What is causing disturbance?

— Identify methods for stopping or reversing the disturbance?

• Develop project goals.

— Use reference sites (nearby sites in natural condition) and/or

— Consult historical sources that describe the pre-disturbance community.

• Remove sources of disturbance.

— Remove toxic materials.

— Remove causes of erosion.

— Reduce overpopulation of species.

Eradicate invasive species.

• Restore processes/natural disturbance cycles such as flood or fire cycles.

— Restore tidal flow.

— Rehabilitate substrates.

— Restore soil texture or chemistry, water regimes or water quality.

• Restore vegetation.

— Direct re-vegetation or seeding of a site using native species suited to local environmental conditions. Where possible a variety of sources within the local region should be used to ensure genetic diversity.

• Monitor and maintain.

— Monitoring restoration sites is critical to determine whether goals are being met. Ideally, restoration projects will eventually achieve a self-sustaining ecosystem without further need for intervention.
