Net ecosystem production of three coastal Douglas-fir stands at different stages of development after harvesting

Elyn R. Humphreys
This thesis examines the differences in stand-level fluxes of carbon dioxide (C02) and the biophysical factors, which affect respiration and photosynthesis in three different coastal Douglas-fir stands  ...  The eddy covariance technique was used to measure stand-level CO2 fluxes in Douglas-fir stands established in 2000, 1988, and 1948 on the east coast of Vancouver Island, British Columbia.  ...  Eighty percent of the trees within the stand were Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirbel) Franco), 17% were western redcedar (Thuja plicata Donn) and 3% were western hemlock (Tsuga  ...
