LMH Effects of Operational Brushing on Conifers and Plant Communities in the Southern Interior of British Columbia
This LMH 4#8 handbook evaluates the long-term outcomes of various operational brushing treatments used to manage competing vegetation in the forests of British Columbia.

By synthesizing data from 96 trials conducted between 1991 and 2000, the report provides a detailed analysis of how different removal methods such as manual cutting, herbicides, and livestock grazing impact conifer growth and overall plant diversity. The document is structured by vegetation complexes, allowing forest managers to access specific findings on competition thresholds and survival rates for different tree species within unique ecological zones. This handbook serves as a silvicultural guide to help practitioners select the most effective and ecologically sound strategies for fostering healthy, productive forests in the province's southern interior. -
LMH the Date Creek Silvicultural Systems Study in the Interior Cedar Hemlock Forests of Northwestern British Columbia
This LMH #38 handbook details the Date Creek Silvicultural Systems Study, a multi-year research initiative in the Interior Cedar Hemlock forests of northwestern British Columbia.

Established in the early 1990s, the project was designed to investigate alternatives to traditional clearcutting by comparing the ecological and economic impacts of various harvesting methods, including light removal, heavy removal, and no-harvest controls. The handbook catalogues the ecosystem mapping, soil profiles, and stand structures of the 4, 000-hectare research area, providing a baseline for understanding how different levels of canopy disturbance affect biodiversity, forest regeneration, and timber productivity. -
FRDA Restoring Productivity on Degraded Forest Soils - Two Case Studies
This FRDA Report #002 investigates the effectiveness of using green fallow systems to rehabilitate degraded forest soils in British Columbia.

Through two distinct case studies in coastal and interior regions, the researcher explores how these cover crops can restore nutrient capital and improve the growth rates of tree seedlings in areas damaged by logging and road construction. The findings indicate that this biological approach successfully accelerates soil recovery by significantly increasing nitrogen and potassium levels, which in turn leads to a substantial enhancement of forest productivity. This doucment serves as a practical guide for land managers, proving that targeted revegetation is a viable economic tool for returning compromised timberlands to a healthy, productive state. -
FRDA Vegetation Development After Clearcutting and Site Preparation in the SBS Zone
This FRDA Report #018 investigates how plant communities recover in the Sub-Boreal Spruce Zone following clearcutting and various types of site preparation, specifically comparing mechanical methods and prescribed burning. The central goal was to det...This FRDA Report #018 investigates how plant communities recover in the Sub-Boreal Spruce Zone following clearcutting and various types of site preparation, specifically comparing mechanical methods and prescribed burning. The central goal was to determine the precise rate of revegetation development and track the resulting shifts in floristic composition and structure across four key ecosystems within the region. By examining how different herb and shrub species survive and recolonize disturbed sites, the findings generate crucial data that informs the creation of predictive models and guides forest managers in planning effective silvicultural prescriptions and wildlife habitat objectives. This study provides a foundation for understanding the long-term ecological consequences of intensive forest management practices in British Columbia. -

The document details the characteristics and definitions of both container-grown and field-grown stock, emphasizing that the correct choice significantly impacts a plantation's survival and early growth. Key sections are dedicated to factors influencing selection, such as species, site limiting factors, and logistics related to ordering and tracking stock types, as well as proper receiving and handling stock upon delivery. This document serves as a comprehensive reference to match specific seedling characteristics with site-specific conditions and cost considerations.
