Help Your Trees Resist Pests
July 17, 2008
On your property, insects and microorganisms abound. This is a natural and beneficial state, since insects and microorganisms are key components in nutrient recycling, decomposition, plant succession, natural pest control and wildlife habitat.
Periodic outbreaks of destructive tree insect pests, as well as diseases, occur as part of natural fluctuations in ecosystems. The actions of homeowners make these outbreaks more severe or lessen their impact locally. To promote a healthy landscape and to prevent pest outbreaks, take steps to ensure diversity and vigor on your property.
Many property owners have lots with just a single or a few trees. Others have small backyard woods, which have become an important component of the urban environment. Small woodlands with a mix of tree species are often less susceptible to pest out-breaks than woods with a single species.
A diversity of tree ages also reduces the risk of pest outbreaks. As with species diversity, age diversity increases the complexity and stability of the ecosystem. A natural balance of organisms is more likely to develop as age diversity increases. For example, potential pests of young trees could be regulated by parasites and predators already well established on older trees.
The first clues of a tree health problem may be symptoms like yellowing needles or leaves, thinning foliage or dieback on upper limbs. These problems may be caused by insect pests or disease pathogens, or they may arise from "abiotic" factors such as soil problems, construction damage, drought, pollution or herbicide injury.
