If a watershed assessment, for example, a CWAP
or IWAP, a sediment source survey, a needs assessment, or
a similar review of impacts of forest harvest in the watershed
suggests potential impacts on riparian habitat, the RAPP
can be undertaken to further identify the locations, nature
and magnitude of impacts on riparian functions, and the opportunities
for effective rehabilitation (i.e., the restoration of ecological
funtion). The assessment procedure (Figure 2) assumes
that known or suspected riparian impacts resulting from past
practices are present in the watershed. The assessment addresses
the following questions:
What riparian habitat is impaired, where is it, and to what
extent is it impaired?
What are possible restoration scenarios?
Which of the degraded riparian sites are the highest priority
In practice, the RAPP will be implemented as an iterative
process. The first stage of RAPP is an overview
assessment to identify areas of potential concern and to indicate the
general nature of the disturbances. The second stage is more-detailed
and quantitative field assessments (Levels
1 and 2) of particular
areas of concern, leading to development of restoration prescriptions
to improve the logging-impaired riparian habitats. Level
2 prescriptions should also include design of maintenance and effectiveness
monitoring procedures to promote and evaluate
the success of the restoration activities, and to allow for
adaptive feedback, if required.
