Vegetation Management

The NCHRP 14-40 project provides guidance for roadside vegetation management to identify the cost, safety, and environmental impacts of routine mowing compared with managed succession of vegetation for areas outside the safety clear zone. Departments of Transportation (DOTs) are re-evaluating their roadside management practices regarding costs and environmental concerns
versus benefits. The ecosystem services provided by minimizing roadside vegetation maintenance practices can include ecosystem diversity, stormwater quantity and quality management, carbon sequestration, conservation and/or restoration of pollinator and/or wildlife habitat, and aesthetics. A key safety benefit comes from reducing maintenance personnel exposure to traffic hazards, equipment, and chemical treatments. This provides both short-term and long-term cost savings and benefits. Overall, managing the roadside as a valued transportation asset consists of taking advantage of the natural ecosystem services that modified
mowing regimes and/or managed succession can provide to see the return in cost/benefit.

Rights-of-way (ROWs) impact habitat primarily through fragmentation and edge effects and also act as vectors for invasive species (weeds). Other potential environmental impacts from ROWs include increased erosion, impacts to stream morphology, etc. Vegetation management can often create conditions that favor weeds and trees! However, ROWs also have the potential to benefit habitat as some plant and animal species need the open areas offered by ROWs and thrive in the edge habitat.
