Nutrient Concentrations of Vegetation in Small Watersheds at H. J. Andrews Experimental Forest, 2005 to 2006

Past research at the H. J. Andrews Experimental Forest has often occurred at different study locations at different times making comparisons between sites difficult. The small watersheds at the Andrews Forest have been the most extensively studied areas at this research forest and this database is intended to provide comparable nutrient information for these watersheds. The samples collected for these nutrient analysis used a uniform method during the summers of 2005 and 2006. Samples were collected throughout each watershed for the following pools; major tree species foliage, major tree species bark, major tree species wood, high shrubs, low shrubs, herbs. These nutrient analysis will compliment the quantification of biomass measurements made over the years in these watersheds.
