Integrated Vegetation Management Plan (IVMP)

Overview

Guardrail before treatmentGuardrail after treatmentThe Integrated Vegetation Management Plan (IVMP) assists the Alaska Department of Transportation and Public Facilities (DOT&PF) in its responsibility to manage the vegetation upon its lands to improve safety, provide improved maintenance services, and control invasive plant species.

DOT&PF manages vegetation to:

  • Maintain roadway sight distance
  • Reduce wildlife strikes
  • Maintain sign visibility
  • Reduce collision targets
  • Provide solar exposure to minimize winter icing
  • Prevent degradation of road surface
  • Prevent degradation of guardrail and fences
  • Provide aesthetic value
  • Preserve environmental and economic condition of adjacent properties
  • Prevent biological pollution (i.e., noxious and invasive weeds)

DOT&PF intends to use herbicides as a maintenance tool, along with non-chemical maintenance and vegetation control measures. While herbicides may be an efficient and effective tool for managing vegetation, herbicide selection and use must be performed in an environmentally responsible manner. Though herbicides can be an important maintenance tool, non-chemical mechanical methods will continue to be the primary method of vegetation management for DOT&PF.

DOT&PF worked closely with the Alaska Department of Natural Resources Alaska Plant Materials Center and the University of Alaska Fairbanks Cooperative Extension Service Agriculture Program to select herbicides that minimize potential risks to human health and the environment. All herbicide applications must comply with local, State and Federal regulations and must be performed by certified applicators using DOT&PF IVMP-approved herbicides in accordance with their labels, the DOT&PF IVMP, and any regional guidelines.

All herbicide applications on DOT&PF managed lands must be done in accordance with this IVMP and 18 AAC 90.

Applications at aquatic sites require an Alaska Department of Environmental Conservation (ADEC) Pesticide-Use Permit and an Alaska Pollution Discharge Elimination System (APDES) Pesticides General Permit. Additionally, regional setbacks may be established for applications adjacent to aquatic sites.
