UBC Camosun Bog Site

Soil Site Details: UBC Camosun Bog Site

Soils on this site are Organic, and they can also be called peat or bog soils. The main component of these soils is organic matter at different stages of decomposition. These soils are often saturated for long periods of time, resulting in low-oxygen conditions below the surface.

Technical Description
The soil at this bog site is of the Organic Order. Soils of the Organic order are the dominant wetland soils found in forested regions of Canada. Organic soils contain 17% organic C (or 30% organic matter) by weight. Most organic soils are saturated with water for prolonged periods, as in this site at Camosun Bog. The diagnostic horizon is either an Of, Oh or Om horizon, depending upon the state of decomposition. The parent material is made up of organic matter overlying glacio-marine deposits. In this case, the organic matter is dominated by sphagnum moss, and many layers have decomposed over time.
