Reduce the occurrence of non-native invasive plants and shrubs to promote adequate natural regeneration of native species. Minimize the mortality to native vegetation and standing overstory trees. Herbicide may be applied year-round, particularly before native leaf flushing and post native leaf drop, for better targeting of non-native invasive plants and reduced native mortality as long as application meets herbicide label requirements. Many treatment areas feature an aspen overstory component that are beginning to send up root suckers. Herbicide application should avoid these aspen root suckers to prevent flashback to the main stems. The Department understands mortality to native vegetation will occur, however, damage considered to be excessive by the Department will be addressed accordingly. Minimize the damage and mortality to amphibians and pollinators Many of the State’s species of greatest conservation need consist of amphibians and pollinators. The type of chemical, season of the year, and time of day should be all be considered in order to help avoid encounters with these species during herbicide application to reduce as much harm as possible.
