ABSTRACT:
	Tree cores were taken from trees in permanent plots within the H.J. Andrews Experimental Forest to estimate annual bole biomass increment. The purpose of measuring this was to determine how many trees need to be sampled within a stand in order to determine NPP accurately. Increment cores were extracted from all trees greater than 5 cm diameter at breast height in each site and measured for annual growth increment (cm). This data was used to explore a method for using increment cores in combination with long-term permanent plots and remeasurement records to estimate annual bole biomass increment.
