MANAGING ROADSIDE VEGETATION IN ALASKA. FINAL REPORT

This report examines the problem of controlling undesirable roadside vegetation, primarily tall wood shrubs and trees, in the central and northern districts of Alaska. Other vegetation management concerns, such as reestablishing vegetation on disturbed areas following road construction and maintaining desirable, low growing species along roadsides are briefly addressed. This report does not directly examine vegetation problems in the much wetter, maritime climate of Southeast Alaska. Roadside vegetation control is a costly, recurring problem for the Alaska Department of Transportation and Public Facilities (AKDOT&PF). Mechanical cutting is the dominant means of control presently, although herbicides were widely used in the past, and these have had some recent but limited use in Southeast Alaska. To reduce most effectively the extent of undesirable woody species along the roadside, it is preferable to use multiple methods, such as mechanical cutting in conjunction with a limited basal spray (herbicide) program or with hand weeding. Such an integrated vegetation management (IVM) approach will help reduce both the number of species as well as the number of individual woody plants that might persist. On the basis of this project, it is recommended that AKDOT&PF develop a long term IVM program that includes vegetation monitoring and a maintenance program to enhance desirable vegetation along roadsides.
