Abstract

120 dominant and codominant trees were selected and felled in fertilized and unfertilized 0.33 ha treatment plots spaced to 500, 750, and 1000 stems per hectare in a 32 year-old stand of coastal Douglas-fir. The sampled stands were spaced and fertilized with 225 kg N/ha as urea in 1977. Stem analysis was used to examine height, diameter, and volume response. Possible changes in stem form resulting from treatment were examined and the accuracy, precision, and repeatability of measurements was determined.
