Economic Data
- WSU Riparian Buffer Experimental Site Installation
and Maintenance Costs: WSU researchers installed a .6 acre
experimental riparian buffer in 2003-04 in Skagit County. The buffer
site was first cleared of blackberries, and the installation included
planting perennial rye grass, red alder, and hybrid poplar. Tree
protectors were placed around individual trees and a fence was erected
to exclude beavers. The buffer area was maintained beginning in 2003
through 2005. Maintenance included grass mowing, weed control with
Round-Up, and replacement of planting stock damaged by beavers. The
total cost of installing and maintaining the buffer area over the
three year period was approximately $7,112 ( Riparian
buffer installation and maintenance costs 22.3kb - requires Adobe Acrobat Reader). Only expenses that would have been incurred in a
non-experimental setting by a private landowner were included in the
total cost. The green pie chart to the right shows how the costs were
distributed between materials, labor and contracted services. The blue
pie chart show how costs were distributed between site preparation,
establishment, and maintenance.
