Tree removal as a tool of ecological restoration in Burns Bog, Delta B.C.

Danyluk, Angela 07 May 2012 (has links)
Burns Bog (the Bog) is a 2800 ha protected peatland in Delta, British Columbia. Globally unique due to its form, size, chemistry, flora and fauna the Bog is distinct and managed as a wetland. In 2005, a large fire consumed 200 ha of peatland after which birch (Betula pendula) and pine (Pinus contorta) trees grew in great densities. Within the fire zone piezometers were installed to monitor water levels below the surface. A high water level promotes peat-forming processes and in 2009 water levels dropped significantly. In 2010, a 75m x 50m experimental plot within the fire zone was cleared of birch and pine trees to investigate the impacts of tree removal on bog hydrology and plant communities. Higher water levels and positive bog plant growth at the experimental site was observed in 2010 and 2011 when compared to the control site where trees remained intact.
