Brochure educates citizens about invasive plants, including what makes an plant invasive, the problems they cause, characteristics, and how to stop the spread of invasive plants. Printed copies available.

The Virginia Department of Conservation and Recreation maintains the invasive plant species list.

Poster helps identify invasive plants, which threaten our forest ecosystems. Designed for 24 in. x 36 in. poster. Target audience: Youth – elementary age.

Invasions of nonnative plants into forests of the Southern United States continue to spread and include new species, increasingly eroding forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. This book provides the latest information on how to organize and enact prevention programs, build strategies, implement integrated procedures for management, and proceed towards site rehabilitation and restoration. Effective control prescriptions are provided for 56 nonnative plants and groups currently invading the forests of the 13 Southern States. A companion book, “A Field Guide for the Identification of Invasive Plants in Southern Forests,” (Miller and others 2010) includes information and images for accurate identification of these invasive plants.

Forestry topic information sheet provides information about the invasive species Ailanthus and possible methods for removing or controlling Ailanthus, including manual as well as chemical methods such as foliar spray, stem injection or basal spray.

Publication provides landowners comprehensive insight to this invasive species, including biology and life cycle, control and elimination methods, utilization of ailanthus, and other resources available. Printed copies available.

As the days turn cooler and shorter, many Virginians are using firewood to keep warm and spend quality time with friends and family. While seemingly harmless, moving firewood can enable the easy movement of destructive forest and agricultural pests. When firewood is moved from one area to another, the invasive emerald ash borer, spongy moth, Asian longhorned beetle, and spotted lanternfly often “hitchhike” to destroy crops, infect more trees and sometimes even entire forests. 

Report provides results from a series of four studies of tree-of-heaven control using triclopyr ester applied at different times during the year by basal spray or cut stump application methods. A mixture of 25% triclopyr ester herbicide in an oil-based carrier achieved excellent tree-of-heaven control for trees up to 16 inches in diameter.

Forestry topic information sheet provides information about possible control treatments for some of Virginia’s most common non-native invasive plant species.
