Forests provide more than just timber—they support wildlife, pollinators, and culturally important plants. A recent study explored how different levels of herbicide use in young forest stands impact both timber production and these vital ecosystem services. The results offer insights into how careful management can support both timber growth and a healthy forest environment.
The study showed that herbicides effectively boost tree growth, leading to higher timber yields. While herbicide use did reduce some native plants, wildlife food sources, and pollinator flowers, other important services, like bird-assisted insect control and pollination for crops like blueberries, remained steady. This means many ecosystem benefits can be maintained alongside timber production.
Initial results indicate lighter herbicide applications may reduce effects on ecosystem services. These lighter applications did not maximize timber growth but supported more native plants and animals through the early years of stand growth. Skipping treatments in some areas or using targeted herbicide applications may help maintain biodiversity without sacrificing productivity.
Researchers conclude with thoughtful planning, forests can provide both economic benefits and environmental services. By judiciously applying herbicides and preserving patches of native vegetation, forest managers can create landscapes that support timber production, wildlife, and plant diversity. This approach offers a promising way to ensure that forests meet a range of needs now and in the future.
