Alternative Silvicultural Systems and Harvesting Techniques for Caribou Habitat

Recognizing that clearcutting leads to habitat loss and increased predation on caribou through apparent competition, the report reviews various silvicultural systems and harvesting techniques, analyzing their potential to maintain old-growth characteristics, limit forage for other ungulates, and minimize access. Through a literature review and expert interviews, the study assesses the applicability of methods like partial harvesting, understory protection, and intensive silviculture in the Alberta context, considering ecological, economic, and practical challenges. The report aims to identify strategies that balance timber harvesting with caribou conservation, acknowledging that site-specific conditions and careful implementation are crucial for the success of any alternative approach. -
Site Preparation Application of Rough and Loose Mounding and Furrowing (RipPlow) on a Wood Mulched Site
This extension note investigates two site preparation techniques, Rough and Loose mounding and furrowing with a RipPlow, for improving plant re-establishment on forested sites that have been wood mulched during winter industrial activities. The study...This extension note investigates two site preparation techniques, Rough and Loose mounding and furrowing with a RipPlow, for improving plant re-establishment on forested sites that have been wood mulched during winter industrial activities. The study evaluated the effectiveness of these methods in displacing the mulch and exposing soil to create favorable conditions for revegetation. While both techniques enhanced surface soil heterogeneity and facilitated the regeneration of deciduous species, Rough and Loose mounding proved more consistently effective at moving the mulch. Despite this, the more cost-effective RipPlow method showed promise, particularly in areas with thinner mulch layers, suggesting that supplemental planting might be beneficial in heavily mulched areas treated with this approach. -
Describing Old Growth Forests in the Boreal Foothills Natural Disturbance Unit
This report examines how to define and identify old-growth forests in the Boreal Foothills of British Columbia, emphasizing that age alone is an insufficient measure.

It introduces an index of old-growthness, a quantitative scoring system based on multiple structural attributes like tree and snag diameters, coarse woody debris volume, and the presence of specific wildlife habitat features. The study aims to move beyond simple age-based classifications, providing forest managers with a more biologically meaningful tool to assess and conserve these vital ecosystems, acknowledging that structural characteristics, rather than just age, are the true indicators of an old-growth forest's ecological value.
