(A) Invasive woody plants. Invasive plants cause ecological disruption to natural ecosystems. The type of impact varies based on the species and the traits of that species. The Woody Invasive Species List is Included in the Urban Forest Management Plan. These species shall not be planted and should be removed and controlled to reduce impacts to other vegetation.
(1) Typical impacts include:
(a) Chemical disturbance to the soil limiting development of other species;
(b) Dense plant growth limiting light to soil surface resulting in exposed soil allowing erosion;
(2) Displacement of naturally occurring species resulting in a monoculture of invasive species and aggressive tendencies.
(3) Private property owner outreach. The village shall have implementation and outreach plan to educate property owners of the potential impacts and remediation strategies, including a suggested planting list of alternative species to assist property owners in dealing with the problem. This plan is located in the Urban Forest Management Plan.
(B) Invasive diseases and insects.
(1) Impacts to trees. Invasive diseases and insects can create significant stress to trees and in some instances kill trees. The Village of La Grange Park has developed a list of invasive diseases and insects that pose significant threats to trees from information identified by State and Federal Departments of Agriculture. This list is included in the Urban Forest Management Plan.
(2) Invasive Species Management Plan. Management of invasive diseases and insects is included in the Urban Forest Management Plan.
(3) Private property owner outreach. The village shall have an implementation and outreach plan to educate property owners of the potential impacts and remediation strategies to help property tree owners in dealing with pests or pathogens. This plan is located in the Urban Forest Management Plan.
