Herbicide usage in invasive non-native plant management (finished and ongoing projects)
Although initially developed for weed control in agriculture, herbicides are widely employed to suppress invasive plants in natural ecosystems. This is particularly true for North America where herbicides are a standard choice to manage invasive species and restore native plant communities. However, how much herbicides are sprayed and to what extent this might harm native plants is not well known. Together with my collaborators, I have launched several projects that 1) investigate the magnitude of herbicide usage in invasive species management in North America and 2) evaluate the effects on native plants. We are using a variety of tools, including data surveys, meta-analyses, greenhouse - and field experiments. The results of our work will provide guidance to restoration practice and land management in North America (and beyond).
