Effect of insecticide treatment on Salix interior stem tannin activity and elemental composition.

This dataset contains information on stem chemistry of Salix interior within experimental plots on the Tanana River. There are 6 permanent plots, each of which contains two fenced subplots and two unfenced subplots. Subplots are sprayed with either insecticide (insect-treated subplots) or water (controls) annually. This particular dataset contains chemistry data for leaves collected from insecticide-treated and control subplots only within fenced subplots. The intent was to measure the effect of insect herbivory on chemistry in the absence of browsing.
