Integrating Roadside Vegetation and Erosion Control

Vegetation management is an important part of integrated roadside management programs. Vegetation control helps highway safety. If left unchecked, weeds and other plants can overrun signage and damage infrastructure. Proper care of roadside vegetation can protect and encourage wildlife and enhance the aesthetic qualities of the highway. A number of states have introduced vegetation management into their integrated roadside management programs. In Washington state, the unwanted vegetation is eliminated and desirable is cultivated. The prevention of weed overgrowth and regularly monitoring conditions are essential parts of the program. It is hoped that with proper management, the roadside vegetation will eventually become self-sustaining. Massachusetts' vegetation management plan provides a safe, unobstructed roadway. The plan has identified priorities for vegetation control and implemented them. Nebraska's plan is focused on encouraging natives plants for a sustainable roadside. The plan includes information about regional ecosystems across the state, for each type of landscape. Iowa's vegetation management program, which was established in 1988, focuses on improving vegetation with the goal of sustainability. Minnesota is developing an integrated plan that includes management of roadsides for the benefit of wildlife. In addition to the control of vegetation, drainage is an important part of roadside management. Poor drainage systems can cause the deterioration of pavement and other parts of roadway infrastructure.
