Restoration on Forestry Road within a Domestic Watershed
Slocan, British Columbia
Slocan Forest Product Ltd.
To rehabilitate a debris flow, restore stability of
the slide, and to re-establish native vegetation. To
reduce sediment delivery to Springer Creek.
Creek is located in the southern interior of British
Columbia. Terra Erosion Control Ltd. developed and implemented
a soil bioengineering prescription to rehabilitate a
debris flow, which was caused by diverted water on an
upper road system within a domestic watershed. The implementation
of the work was carried out at the end of July 1998.
The site was stabilised through soil bioengineering
techniques such as; wattle fences, live gully break,
live staking, and live smiles using local willow cuttings,
which had been in cold storage for a period of four
months. The site was re-assessed for growth during the
fall of 1998 and the willow cuttings showed a survival
rate of 98%. The site was then monitored again in the
summer of 1999 and 2001. The results of this monitoring
showed functioning structures; in addition, the live
sediment trap using a wattle fence system in the lower
portion of the slide successfully trapped a large amount
of sediment while the vegetation was establishing.
