Fertilization responses at the stand-level have been quantified for western redcedar and western hemlockx000D
plantations in coastal British Columbia (BC). However, the routinely applied growth and yield models operatex000D
at the tree-level and understanding of tree-level responses to fertilization treatments in coastal BC is limited.x000D
With a renewed interest in fertilization responses for carbon sequestration and storage, forest industry in BCx000D
faces the challenge to better understand tree-level responses to fertilization treatments in order to refine theirx000D
forest fertilization applications. This project will use 30 years of re-measurement data from long-termx000D
silvicultural trials in the Salal Cedar Hemlock Integrated Research Program from Northern Vancouver Island,x000D
BC, to quantify the tree-level responses to nitrogen fertilization for both western hemlock and western redcedarx000D
in three planting densities (500, 1500, 2055 stems/ha). The analysis performed in this project will lay thex000D
groundwork for building a TASS fertilization module for coastal BC. Ultimately, the work will allow BC forestx000D
industry to refine their fertilization management applications to further increase their timber production andx000D
improve their carbon sequestration strategies. The proposed approach can then be adapted to other tree speciesx000D
and forest types in BC and across Canada.
