Bioequivalence Ratio
Experimental / Reference
oExperimental = area undergoing restoration
oReference = target area
Closeness to being restored:
o0.2 = not close
o0.5 = halfway to target
o1 = completely restored
What are we Attempting to Restore?
Need to clarify goals
Some subtle distinctions in terminology:
oRestore
Return ecosystem to condition prior to disturbance
oRehabilitate
Return to previous condition but not necessarily as complete as
restoration
BETTER than restoration
oReclaim
Make good for a specific purpose
oReplace
Substitute ecosystem with one of enhanced function
oRemediate
Fix problem to make fit for some purpose
oEnhance
Replace ecosystem with an increased function
oMitigate
Compensate for loss of habitat by changing one habitat for
another
E.g. wetland banking

Restoration Goals Should = Explicit Targets
To get reference conditions to be targets
Best are:
oReal, still existing habitats or viable populations that can be sampled
throughout monitoring
Where this is not possible, need to “construct” such form of quantified aspects
of ecosystems
More useful, quantifiable targets
IDENTITIY
oSpecies list = taxonomic composition
Relative abundances = evenness
SELF-SUSTAINING
oSize or age structure, maturity, reproductive status of constituent
populations
FUNCTION
oInteracting species, including indirect effects = ecological processes
oRates of ecological processes
SCAPE ECOLOGY
oSpatial arrangement of individuals of different species
VARIABILITY
oBaselines of natural variation
Potential Sources regarding Reference Data
Data sets from before
oYour own or others
Scientific papers
oLimited time frame

Document Summary
Experimental / reference: experimental = area undergoing restoration, reference = target area. Closeness to being restored: 0. 2 = not close, 0. 5 = halfway to target, 1 = completely restored. Some subtle distinctions in terminology: restore. Return ecosystem to condition prior to disturbance: rehabilitate. Return to previous condition but not necessarily as complete as restoration. Make good for a specific purpose: replace. Substitute ecosystem with one of enhanced function: remediate. Fix problem to make fit for some purpose: enhance. Replace ecosystem with an increased function: mitigate. Compensate for loss of habitat by changing one habitat for another. To get reference conditions to be targets. Best are: real, still existing habitats or viable populations that can be sampled throughout monitoring. Where this is not possible, need to construct such form of quantified aspects of ecosystems. Self-sustaining: size or age structure, maturity, reproductive status of constituent populations. Function: interacting species, including indirect effects = ecological processes, rates of ecological processes.
