Invasive Weeds

Background

  • The National Invasive Species Council defines “invasive species” as a species that is 1) non-native (or alien) to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health (Executive Order 13112).

Ongoing Projects

  • August 24 2012.  The Forest Supervisor signed a Decision Notices and Finding of No Significant Impact for the Environmental Assessment for Integrated Treatment of Noxious or Invasive Weeds proposing to contain, control, or eliminate populations of noxious weeks and invasive plants occurring on the Tonto National Forest and to prevent new infestations from being established.  Treatment methods include:  mechanical, prescribed burning, cultural, use of biological control agents, and use of herbicides.

  • Aug. 5, 2013.  The forest is requesting bids for noxious weeds survey for the Myrtle  4 Forest Restoration Initiative (4 FRI) project.  Click below to see the map of the project area which depicts the roads and fuel breaks to be surveyed.
  • In January 2010, the Tonto was successful in obtaining a grant from the Eastern Arizona Resource Advisory Committee to conduct weed control in Gila County. Funding will be shared with the Town of Star Valley, who has been very proactive in controlling their yellow starthistle infestations, and the Arizona Department of Transportation, who works to maintain highway rights-of-way free of noxious weeds.
