Invasives

Managing invasive plants in Virginia is crucial for preserving the state’s native ecosystems and biodiversity. Invasive plants have the potential to outcompete native species for resources such as sunlight, water, and nutrients, leading to a decline in native plant populations.

This disruption can have cascading effects on the entire ecosystem, impacting wildlife habitat, soil health, and even water quality. Additionally, invasive plants can pose significant economic costs, such as reducing agricultural productivity and increasing expenses for landowners and managers tasked with controlling their spread.

By actively managing invasive plants through strategies like monitoring, control efforts, and public education, Virginia can protect its natural heritage and ensure the long-term health of its ecosystems for future generations.

The resources below will help you identify and manage the invasive plants on your property.  Remember if you have questions, you can contact our help desk.
