Abstract

Pollen analyses of two peat post-Vashon bogs in southwestern British Columbia show that the pioneer postglacial forests consisted largely of lodgepole pine, suggesting an initial cool and damp period. This was followed by a spruce-pine forest with a predominance of spruce, indicating an increase in moisture and temperature. A third period of decreasing moisture and temperature is marked by the increase and dominance of Douglas fir and hemlock, which has existed to the present. The method of formation of Lulu Island, its physiographic and edaphic instability, its position in relation to winds and adjacent forests, and plant succession on the island and bog are responsible for an inaccurate representation of nearby forests by their pollen as preserved in the peat. The Westminster bog, however, probably records a fairly accurate representation of adjacent forests. Climatic interpretations are tentative but essentially agree with those of pollen analyses of other bogs in the Pacific Northwest. (Author's summary)
