Description
Invasive species are a major concern for many ecologists, park managers, and restoration scientists. The empty niche hypothesis proposes that introduced plant species become invasive because they can exploit unused resources, or empty niches, in a community. This study looks for empty niches by using historical descriptions of local wetlands to make models based on native species and their resource use. If there are any gaps in resource use that a commonly invasive species, Phalaris arundinacea (reed canary grass), Typha angustifolia (narrow-leaf cattail) or Typha x glauca (hybrid cattail), would fit into, then that wetland will be considered to have an empty niche. Wetlands with an empty niche should have the invasive species currently present; this will be examined in field studies, along with the degree to which the invader is in the niche indicated by the model.
