Conifer needle processing in a subalpine lake 1

Abstract

Fir and hemlock needles lost an average of 80–90% of their initial dry weight after a 1‐year incubation on a littoral benthic site in Findley Lake, Washington. Considerably less mean weight was lost from needles in fine and coarse mesh bags. In all treatments there was little change in mean needle weight during the second year of the experiment.
