Invasive Species

Invasive species of insects and disease have the potential to not only destroy individual trees in our urban areas but entire forests.  OFS works with the USDA's Animal and Plant Health Inspection Service (APHIS) to stop any new introductions of foreign plants, plant diseases and insects. 

Historical introductions of invansive species having catastrophic results include Dutch Elm Disease and Chestnut Blight.  Introduced invasive species of concern in Oklahoma are Gypsy Moth, Emerald Ash Borer, and Introduced Wood Wasp.
