Laminated Root Rot in the Pacific Northwest: A Growing Concern.
Forests play a crucial role in the region’s ecology and economy, and the widespread nature of LRR threatens biodiversity and the sustainability of timber industries.

Explore the impact of Laminated Root Rot on Pacific Northwest forests, affecting biodiversity and timber industries, with expert arborist insights.
Laminated root rot (LRR), caused by the fungal pathogen Phellinus sulphurascens, is one of the most destructive diseases impacting forests in the Pacific Northwest. This pathogen primarily affects conifer species such as Douglas fir, grand fir, and western hemlock, compromising the health and stability of these trees. The fungus spreads through root contact, breaking down the root systems and creating a laminated structure in decaying wood, hence its name.
In forested areas, LRR can devastate large sections of land by killing trees and reducing timber yield. The loss of mature trees creates gaps in the forest canopy, altering habitats and leading to increased soil erosion. As forests play a crucial role in the region’s ecology and economy, the widespread nature of LRR threatens biodiversity and the sustainability of timber industries.
The spread of LRR is not confined to forests; urban environments in the Pacific Northwest are increasingly at risk. Parks, greenbelts, and residential areas where conifer species are planted have become susceptible, posing a threat to urban tree cover and infrastructure. In cities, infected trees can fall without warning due to weakened roots, creating significant safety hazards.
Addressing the issue involves early detection, the removal of infected trees, and managing reforestation by planting resistant species such as western redcedar or hardwoods. With climate change potentially exacerbating the spread of LRR, ongoing research and forest management strategies are critical for preserving both urban and wild forest ecosystems.
