Abstract/Description or Keywords Burns Bog covers approximately 3,000 hectares between the Fraser River and Boundary
Bay in Delta, BC. An ecologically unique ecosystem, its hydrology and ecology have been
widely disturbed. Hydrology strongly shapes the character and distribution of vegetation and
Sphagnum growth. This study investigated measures of hydrology, including water table
residence times and cumulative moisture deficits, to quantify intuitive relationships between
moisture stress and ecological zones. Regression analysis of quantitative field observations
reveal statistically significant relationships between cumulative moisture deficits and several key
bog plant species and Lodgepole pine (Pinus contorta) diameter at breast height, signifying that
these relationships can be used to predict the potential for vegetation recovery. Sphagnum height
measurements reveal the unexpected observation that most growth occurs during the cool moist
winter and early spring. This study contributes to the hydrological management of Burns Bog
and will help to guide the location and mechanisms of restoration efforts.
