Multiple Projects with Coconino County and the City of Flagstaff

Since 2010, EnviroSystems has specialized in noxious weed management for the local community. We have provided herbicide treatments throughout Coconino County along county road rights-of way, material pits, and transfer stations. We have provided manual or mechanical treatments for the City of Flagstaff within designated open spaces, water treatment plants, selected drainages, and recreational areas.  This work is particularly rewarding because we can serve and rehabilitate the natural environment for our local community.
