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.

This document reviews existing research on the relationship between aspen forests and wildfire, particularly in the context of British Columbia. It explores aspen's inherent fire-resistant characteristics, such as high moisture content and unique regeneration, which contribute to reduced wildfire spread and intensity. The document examines the potential for utilizing aspen in wildfire management strategies, including as natural fuel breaks, while also acknowledging conditions like drought that can compromise this resilience. The author identifies knowledge gaps and suggests preliminary strategies for promoting and managing aspen to mitigate future wildfire risk in a changing climate.

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.

This document synthesizes existing research on the intertwined relationships between woodland caribou, wildfire, and forestry practices in Canada. It systematically explores how these two types of landscape disturbances impact various aspects of caribou ecology, including habitat selection, movement patterns, population demography, and the availability of their primary forage. The review compares the effects of wildfire and forestry, aiming to inform sustainable forest management strategies and caribou recovery efforts by understanding how human activities can better emulate natural disturbance regimes.

This document outlines the critical need to braid Indigenous Knowledge and Western Science to create climate-adapted forests in the United States. A primary theme is the historical impact of Euro-American colonization, fire exclusion, and settler colonialism on North American forest ecosystems, leading to the loss of Indigenous stewardship and creating dense, fire-maladapted landscapes highly vulnerable to severe wildfires and climate change stressors. The text defines IK as an invaluable, multi-generational body of systemic knowledge and cultural practices emphasizing kinship with nature and reciprocity, contrasting it with the empirical and objective approach of WS.

This presentation focuses on the establishment and growth of aspen stands within the Sub-Boreal Spruce zone of British Columbia. It draws upon existing research to discuss key factors influencing aspen regeneration, including the importance of removing apical dominance through disturbances like logging or fire to promote suckering. The presentation also details harvest considerations, such as the benefits of winter harvesting and the negative impacts of excessive canopy retention and soil compaction. The presentation explores the effects of various silvicultural practices and the interactions between aspen and coniferous species like spruce and pine, providing guidance on site selection and stockingregeneration surveys for successful aspen management.
