Series: Forest Investment Account (FIA) - Forest Science Program


The objective of this project is to document the 30-year growth response of a Douglas-fir (Pseudotsuga mensiesii (Mirb) Franco) stand to thinning and fertilization. The initial thinning and fertilization treatments were carried out when the stand was 24 years old, with second fertilizer treatment applied 9 years later. Growth responses will be analyzed on a per hectare, individual tree, crop tree and tree size class basis, and compared with growth response for previously measured intervals
