By testing 23 different seed sources across 12 diverse locations, the author examines how various environmental conditions and genetic origins influence the tree's performance. The findings indicate that while the species is highly productive and resilient in maritime climates, it remains vulnerable to frost in more continental settings. This document aims to identify ideal planting sites and superior seed sources to guide the successful introduction of noble fir for regional reforestation. -
Grizzly Bear Habitat in Managed Forests - Silviculture Treatments to Meet Habitatand Timber Objectives
This document details methods for integrating grizzly bear habitat conservation with commercial logging objectives in the Coastal Western Hemlock zone of British Columbia, where rich timberland overlaps with crucial bear foraging areas.

The primary goal is to provide silviculture guidelines that allow managers to maintain commercially viable stands while enhancing the abundance of bear forage throughout the forest rotation. Key strategies involve manipulating stand density and canopy closure through techniques like cluster planting and spacing, creating light gaps sufficient for understory food plants to thrive. The implementation of these standards requires application at multiple planning levels and relies heavily on a continuous adaptive management approach for monitoring effectiveness and refining prescriptions over time.
