CREEK RESTORATION PROJECT
reach of Cottonwood Creek in Nelson, BC
Rod & Gun Club/Nelson Cottonwood Creek Restoration
native shrubs along banks of Cottonwood Creek. Stabilize
eroding sections of creekbank using vegetated riprap
applications and create fish habitat.
to this project, the banks along the lower reach of
Cottonwood Creek were dominated by invasive weeds and
grasses, especially Common Tansy, combined with areas
of native brush cover. In order to improve fish and
wildlife habitat in this area, Adam Kowalyshyn of the
Nelson Rod & Gun club contacted Terra Erosion Control
Ltd. (TEC) to develop a native shrub planting prescription,
excluding trees, due to the proximity of the airport.
the spring of 2006 a TEC representative visited the
site and determined a list of suitable native shrubs
and located suitable areas for planting along the creek.
A total of 10 species of native seedlings were selected
and obtained from local nurseries. The volunteers were
instructed on correct planting procedures and micro-site
selection. TEC supervised and coordinated the planting
of these shrubs during the spring, with a group of volunteers
from the Rod & Gun Club.
also provided input and assistance to the volunteers
with weeding and watering/fertilization of the planted
seedlings during the season of 2007.
the early spring of 2008 a vegetated riprap application
was installed to stabilize two sections of bank erosion
along the creek. A small section was installed below
a storm water outlet and the other adjacent to a pedestrian
bridge. TEC designed the treatments and supervised the
work, which was carried out using TEC personnel as labour.
The City of Nelson donated a backhoe and operator and
the Rod and Gun Club provided a volunteer to direct
traffic. In addition to the vegetated riprap applications,
long live stakes of willow and red osier dogwood were
planted on a sand bar within the creek channel to create
“live shade” and further improve fish habitat. Adam
Kowalyshyn from the Rod & Gun Club was instrumental
in co-ordinating the logistics of this work.
of the summer of 2008 many of the planted shrubs were
doing well, although a portion of them had died. Overall
the treatment has substantially improved shrub density
along the lower reach of Cottonwood Creek and will provide
additional riparian cover in the future.
