General principles to consider when undertaking wetland

restoration (Bardsley et al. 2001)
provides a useful summary of the steps that need to be taken when deciding on
habitat restoration in a specific location. The "Steps to consider"

Guidance: This guide sets out to provide information on restoring
individual habitats. However, wetlands (especially estuaries
and other tidal wetlands) are complex systems. Restoring one habitat,
for example saltmarsh, when undertaking managed
realignment may be at the expense of other areas of value.
It will be extremely important to consider these 'knock-on' effects, including
the value of transitional
habitats before proceeding with a particular scheme.
Comment: In the USA there are many generic publications for example
the US Environmental Protection Agency, Office of Wetlands, Oceans and
Watersheds (http://www.epa.gov/owow/estuaries/)
which also sets out some guiding
principles to habitat restoration.
