The Roadside Vegetation program is responsible for managing vegetation in ditches, storm water facilities, off-street bike paths, pedestrian areas, and rights-of-way. Its goal is to maintain a safe, healthy, and attractive environment.
Roadside maintenance is managed with a full complement of methods: mechanical (tractor mowing), cultural (hydroseeding and planting appropriately), biological, and chemical.
The project is designed to locally address the nationwide concern over invasive noxious weeds. Currently, 94 kinds of foreign weeds infest over 100 million acres in the U.S. Infested areas continue to increase by 8 - 20% per year. Livability, recreation, agriculture, and wildlife habitat are threatened (2/3 of all threatened and endangered species' habitat is thus endangered). Public natural areas are being lost at an estimated rate of 4,600 acres/day.
The Tri-County Invasive Species Committee combines efforts of local, county, state and federal agencies and the community to promote compliance with State Law, implement good science and agency consensus, share the latest and best information, and recommend native plan species to compete with invasives.
Using an integrated vegetation management methodology, agencies proactively control proliferation of noxious weeds in Portland's public spaces. The methods reduce the time and cost of repetitive mowing.
