Native bog species prefer a high water table with low nutrient, high acid conditions.  These conditions existed at Camosun bog for 2000 years.  When the City of Vancouver encroached upon Camosun bog, drains were installed. Water levels went down.  sphagnum moss died, decayed and became soil.  nutrient levels went up.  Invasive species easily outcompeted the bog plants in these new conditions.  A hemlock forest crept in through the process of ecological succession.  Read about the history of Camosun bog here.
