When assessing an area for restoration,
the City of Bellingham takes into account the unique attributes of the site
and applies the appropriate restoration techniques.
In areas plagued by a massive load of
invasive vegetation the invasive species must first be removed or
Species planted in restoration project sites are tailored to match site
conditions including soils, sunlight, and landform. The species are also
patterned after native plant associations that are currently or historically
found at similar sites. An
assessment of historic forest conditions (PDF) that would have occurred
along city streams is used to tailor current planting plans.
Once plants are installed, the sites must be maintained to ensure that native
species survive and thrive. In areas where beaver are present young trees
and woody shrubs are enclosed in wire fencing to deter browsing from deer,
rodents and beaver. When the trees grow beyond a critical phase, where they
are able to withstand natural browse, the wire cages will be removed to
eliminate the inhibition of growth. The Washington
Conservation Corps crews continue to control invasive weeds at each
site, performing maintenance at least three times each year.
