Summer and the warm growing season offer plenty of food for forest plants and forest wildlife to reproduce. Some wildlife species are a bit less desirable to many people, such as forest tent caterpillars, spruce budworms and Lecanium scales.
To a forester, the outbreaks of native insects and pathogens can be an interesting part of the job. From an ecological viewpoint, these impacts can be regenerative and fascinating. To a backyard barbecuer, picnicker or a home landscape enthusiast, some of these events can be annoying.
