An evaluation of the distribution of ecological information on Alliaria petiolata (garlic mustard) to invasive species managers in Missouri and Illinois.

Garlic mustard (Alliaria petiolata) is an introduced, allelopathic plant species that has invaded many natural areas in the Midwest. It fills large areas of land, excluding other native plant species, and is avoided by deer and other herbivores. Land managers of natural areas in 28 states are engaged in an on-going struggle to control established garlic mustard populations and limit the spread of the invasive. Although there have been many ecological publications about garlic mustard biology, the results of which should substantially influence management techniques, the incorporation of this new knowledge into management efforts is seldom evaluated. We designed and distributed an online, 15-question survey for managers of natural areas (including state, federal, and private organization employees) in Missouri and Illinois. The questions were designed to assess the range of methods used in garlic mustard control, the sources used to obtain information about invasive species biology and control, the time and money devoted to garlic mustard in invasive species control programs, and the level of success that managers have had in controlling garlic mustard. Our results could be used to design new, more effective ways of disseminating information about species biology and advances in management techniques to different groups of natural area managers. These measures could result in more efficient use of funding to control the species.
