Maine's Spruce Budworm Policy [PDF]
The Forestry Chronicle, 1985 In the 1970s an outbreak of spruce budworm, combined with rising protection costs, environmental concerns, and recoghition of the long-term nature of the infestation, demanded new approaches to forest management and protection. Through adapting traditional policy, frequent conflict and innovation, the Maine Department of Conservation and private ...

Evidence of negative density‐dependent dispersal in an invasive forest pest
Ecosphere, Volume 17, Issue 4, April 2026.Abstract Understanding the mountain pine beetle's dispersal patterns is critical for evaluating its threat to Canada's boreal forests. It is generally believed that higher beetle densities lead to increased long‐distance dispersal. One possible explanation is that beetle aggregation pheromones become repellent at high concentrations, causing beetles to

Three Centuries of Synchronous Forest Defoliator Outbreaks in Western North America.
PLoS ONE, 2016 Insect outbreaks often occur synchronously across large spatial scales, but the long-term temporal stability of the phenomenon and the mechanisms behind it are not well understood.

Prevailing winds and spruce budworm outbreaks: a reaction-diffusion-advection model
Mathematics in Applied Sciences and Engineering, 2021 We extend the classical reaction-diffusion model for spatial population dynamics of spruce budworm on a finite domain with hostile boundary conditions by including an advection term representing biased unidirectional movement of individuals due to a ...

Global Change Biology Communications, Volume 1, Issue 1, March 2026.Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

Distilling food web dynamics: top–down and bottom–up drivers of extinction and trophic cascades
Oikos, Volume 2026, Issue 3, March 2026.Quantifying population dynamics is a fundamental challenge in ecology and evolutionary biology, particularly for species that are cryptic, microscopic, or extinct. Traditional approaches rely on continuous representations of population size, but in many cases, the precise number of individuals is unknowable.
