Untapped Provenances of Sitka spruce
Carried out by: Forest Research
This project will focus on providing information on Sitka spruce by directly measuring relevant traits on a mature forest trial of 25 Pacific Northwest origins of Sitka spruce growing in northern Scotland. These traits are: growth, wood stiffness, wood density and tree ring characteristics related to drought vulnerability. A rapid, preliminary study at the project site in 2019 has indicated that important differences could exist and more reliable time series measurements are now sought with this proposal. The variation within and between seed origins will be compared for the measured traits and the findings used to inform planting strategies and to guide the future breeding of Sitka spruce in the UK.
