Central Valley Greenway Riparian Restoration

The Central Valley Greenway provides a recreational and commuter route connecting New Westminster, Burnaby, and Vancouver. As part of the section through the Still Creek – Burnaby Lake area, the City of Burnaby’s committed to restoring riparian habitat where the greenway passed through degraded riparian areas. Most of this section supports dense thickets of Himalayan blackberry and a stream margin dominated by reed canary grass with only limited areas of native riparian forest or shrub communities. Previous channel maintenance and browsing of shrubs and trees by beavers has contributed to the prevalence of non-forested plant communities.

The project had two objectives: (1) to restore native riparian forest in areas dominated by invasive plants; and (2) to test restoration techniques that could be used in other sites in the Still Creek corridor. Our work focused on the use of different site preparation (no cutting, cutting, tilling) and mulching (no mulch, green chip, cardboard and green chip, and black plastic) techniques. Sites were laid out to have side-by-side comparisons of different treatments. A portion of the work was completed from February to May 2012 and the planting phase will be finished by November 2012. Maintenance and monitoring will continue for 5 years.
