Abstract
A post-glacial record of diatoms from subalpine Sicamous Creek Lake, British Columbia is presented in context of landscape and vegetation change, based on palynological evidence. Diatom-based water quality and pH changes slightly from the lake’s origin to present day, and the ratio of benthic – planktonic diatoms provides evidence of moderate lake level fluctuation. Deposition of Mazama and Mt. St. Helens volcanic tephra layers indicates shortterm changes in both terrestrial and aquatic ecosystems. The shift in primary forest composition from pine to ESSF in the late Holocene is reflected in water chemistry and biotic response. Multi-proxy paleolimnological studies show great promise in documenting terrestrial-aquatic interactions over long time periods.
