Species and Spacing Trials in the Montane Forest Region (SubBoreal Spruce Zone, Prince George Forest Region)(EP 660)
Last updated on August 22, 2023On this page:
Introduction
This experiment was established in 1967 to evaluate and compare the performance of plantations of white spruce, lodgepole pine and Douglas-fir at various espacements on three different plantations with the Prince George Forest Region.
Objectives
To:
- Establish pure, replicated plantings of Douglas-fir, lodgepole pine and white spruce at different densities
- Monitor these plots with periodic evaluations of survival, incidence of damage and disease, and growth and yield for each species-espacement combination
- Maintain each installation of the project as a long-term demonstration and teaching area
Treatments
There are 3 research sites: Buckhorn Ridge located 45km southeast of Prince George; Bobtail Road site is located 60km southwest of Prince George; and Chilco Creek site located 65km northwest of Prince George. Treatments included plantings at 2, 3, and 4m square spacings in 1967. Additional plots were established at Buckhorn Ridge site only, planted at 1.5m in 1968. Plots size varied with density.
Status
