This FRDA Report #146 evaluates the effectiveness of a brown and burn forest management strategy used to transform brush-heavy land in coastal British Columbia into productive conifer plantations. The study specifically compares the environmental impacts and seedling growth outcomes of applying glyphosate herbicide either one year prior to or in the same year as a prescribed fire. By meticulously measuring nutrient status, soil properties, and vegetation regrowth, the author concludes that both methods are feasible for site rehabilitation and the earlier herbicide application generally led to greater fuel consumption and better suppression of competing plants. This document can assist with optimizing site preparation techniques to ensure the successful establishment of Douglas-fir seedlings in specific ecological subzones.

This document examines a twenty-year study in British Columbia regarding the complex relationship between red alder and two conifer species, Douglas-fir and western redcedar. While alder is often removed by foresters because it competes for light and space, it also provides essential benefits by naturally fertilizing the soil with nitrogen. The findings suggest that maintaining a specific density of 100 to 200 alder trees per hectare can actually support conifer growth, particularly on nutrient-poor sites. The authors conclude that traditional forestry assessment methods may be inadequate, recommending a larger plot radius to more accurately measure how these different tree species interact and compete over time.

This report examines the projected impacts of climate change on British Columbia's forest and range resources. It begins by outlining future climate scenarios for British Columbia, emphasizing anticipated increases in temperature and shifts in precipitation patterns based on global climate model projections. The report explores the potential ecological and economic consequences of these changes, including effects on species distribution, forest disturbances like fires and pests, and resource management practices. Finally, it proposes a framework for developing adaptation strategies and offers recommendations to proactively address the challenges posed by a changing climate.

The Coastal Douglas-fir Conservation Partnership is a collaboration of agencies, organizations and land managers who are interested in promoting and protecting healthy Coastal Douglas-fir and associated ecosystems into the future. The mission of the CDFCP is to promote the conservation and stewardship of the Coastal Douglas-fir and associated ecosystems in south-western British Columbia through sound science, Indigenous knowledge, shared information, supportive policies, and community education.
