Tomentosus Root Rot Forest Health Stand Establishment Decision Aid

This document serves as a stand establishment decision aid for forest managers in British Columbia dealing with tomentosus root rot, a fungal disease prevalent in spruce and pine forests. It outlines the characteristics and spread of the disease, emphasizing its impact on forest health and productivity through mortality, growth reduction, and windthrow. The guide details how to identify susceptible stands based on species composition and site conditions, discusses methods for assessing disease presence after harvesting, and presents silvicultural considerations like inoculum reduction and the planting of less susceptible tree species to mitigate future issues. The purpose of this document is to inform forest management practices in areas where tomentosus poses a significant risk to ensure healthy and productive future forests.
