This document outlines the principles and specific strategies guiding forest management within the Aleza Lake Research Forest. It's structured into key sections covering silvicultural practices, goals, and standards, emphasizing a balanced approach to timber production, ecological values, research, and education. The document details aspects like reforestation methods, species selection, rotation lengths, and management of competing vegetation, all while considering climate change adaptation and forest health. This document serves as a comprehensive guide for ensuring sustainable and diverse forest management on the ALRF landbase, aligning with both provincial regulations and the unique objectives of a research and demonstration forest.

This document evaluates the early success of the Northern Wetbelt Silvicultural Systems Project, a long-term study comparing how different logging methods affect forest health in east-central British Columbia. Researchers analyzed initial survival rates of planted spruce and cedar alongside the frequency of wind damage to residual trees across various harvest intensities, ranging from clearcuts to partial-retention systems. Their preliminary findings indicate that seedling survival is exceptionally high across all sites, while the risk of trees snapping or uprooting increases moderately as more of the surrounding forest canopy is removed. By providing baseline climate data and specific monitoring recommendations, the document serves as a foundational assessment to guide sustainable forest management and ecological restoration in the interior cedar-hemlock subzones.

This extension note investigates recent changes in aboveground live-tree carbon within spruce and fir-dominated sub-boreal forests in the interior of British Columbia. The study specifically re-evaluated carbon stocks between 20032004 and 2018 at the Aleza Lake Research Forest to understand how carbon storage is impacted by tree species and size. The authors found that while younger forest stands generally accumulated carbon, older stands with larger trees showed a decline in aboveground live-tree carbon, largely due to increased mortality of these large trees. This highlights a critical concern regarding the role of mature forests in carbon sequestration amidst accelerating climate change and increasing tree mortality rates.

This document introduces an innovative old-growth index developed to accurately measure and track the ecological value of forests, especially those prone to disturbances. Moving beyond traditional age-based definitions, the researchers used Aerial Laser Scanning (ALS) and field data to create a more comprehensive metric that considers diverse structural attributes like tree size, deadwood, and canopy complexity. The study's application in British Columbia's Chinook Community Forest revealed that "very-high" old-growth value forests are scarce and fragmented, often located outside designated protected areas. This research provides a flexible and robust framework for forest managers to better conserve and monitor these vital ecosystems and their services, aiding in more effective landscape-level planning.

The Sustainable Forest Management certificate is a flexible, career-focused program designed for forestry professionals aiming to advance their skills or pursue Registered Professional Forester designation. Delivered through three stackable micro-credentials, the program covers forest ecology, silviculture systems, harvesting practices, and forest health management. Learners gain practical, applied knowledge to assess forest disturbances and implement sustainable management strategies.

The Aleza Lake Research Forest is a 9000 ha university-based outdoor research facility and working forest 60 km east of Prince George, BC. The mandate of the Research Forest is to provide research and education facilities and opportunities to the University of Northern BC and other institutes, universities, government agencies, private sector research, schools and other educational groups with regards to ecosystem and resource management studies within the wet sub-boreal spruce biogeoclimatic zone. The research and education programs are multidisciplinary with an emphasis on: Partial cut harvest systems, Biological Diversity, Climate Change and Environmental Monitoring in Small Forest Tenures. The Aleza Lake Research Forest provides a location for field research and education, and also facilitates the development, implementation and evaluation of research and education programs with the user groups.

John Prince Research Forest (JPRF) is a unique institution, envisioned, initiated and managed cooperatively between Tl'azt'en First Nation and the University of Northern British Columbia. Developing innovative approaches to natural resource conservation and management that combines First Nations' traditional and western scientific approaches to understanding the natural world, is what makes John Prince Research Forest special. Located in the dry sub-boreal spruce biogeoclimatic zone of the Nechako Plateau, the northernmost subdivision of BC' s Central Interior Plateau. The JPRF falls within the moist interior natural disturbance unit, characterized by large wild fire stand replacement events typically on a 100-200 year cycle. The natural forest types are an uneven-aged mix of Douglas-fir, spruce, pine, subalpine and deciduous types. These highly productive northern forests have distinctive understories of rose, spirea, soopallie, cranberry, thimbleberry, red osier dogwood, black twinberry, devil's club and huckleberry varieties.

This presentation focuses on managing forests for resilience as a crucial method for achieving both forest sustainability and value. It begins by establishing the importance of resilience in the context of forestry, defining it across ecological, engineering, and social-ecological perspectives, and distinguishing between general and disturbance-specific resilience. The presentation then explores how to promote resilient forests, emphasizing the role of diversity, complexity, and understanding ecological systems. Through case studies and management principles, it demonstrates practical ways to enhance forest resilience at various spatial scales, acknowledging the inherent trade-offs in managing for future uncertainties like fire, insects, drought, and climate change.

This extension note presents findings on the pre-harvest forest conditions at a group selection logging site within British Columbia's Interior Cedar Hemlock zone. The study's central purpose was to document the stand structure and the presence of wildlife habitat attributes in this old-growth forest before a partial cutting silvicultural system was implemented. By examining aspects like tree species, size, age, and the occurrence of features important for wildlife, the authors aim to provide foundational information for understanding the ecological impacts of partial cutting as an alternative to clearcutting in these valuable ecosystems.

This study addresses the ecology and management of interior Douglas-fir at the northern extent of its range in British Columbia, particularly within the Prince George Timber Supply Area. The study delves into concerns about a perceived decline in Douglas-fir abundance, exploring its ecological, cultural, and economic significance in this northern environment. It synthesizes existing knowledge on Douglas-fir, examining past and present management practices, its role in local ecosystems including wildlife habitat and soil health, and challenges related to its regeneration, often comparing it with other species like lodgepole pine and spruce. The document serves as a problem analysis and aims to inform the development of an interim management strategy and future research directions for sustaining Douglas-fir in these unique northern landscapes.
