In-Depth Information
Myers and Bazely (2003) proposed two key areas of study that are important in
determining the invasiveness of a given species: (1) interactions between invasive
species specifically (as well as the impact this has on existing community structure
and function), and (2) the interactions between and evolution of plants and soil
organisms. Given the high reproductive outputs of swallow-worts, the unknown
role of vegetative expansion, and the clear impacts that swallow-wort invasions
have on both belowground and aboveground communities, it is vital to prioritize the
investigation of interactions between the swallow-worts and the biotic communities
in invaded habitats (Greipsson and DiTommaso 2006; Mitchell et al. 2006; Smith
2006; Smith et al. 2008). This information is necessary to further our understanding
of the invasion process in these congeneric perennials and to develop strategies that
may prove effective for eventual control and management of the species. Given
their rapid spread across the Northeastern USA and our inability to successfully
control these invasions, we must rapidly devote additional resources to study the
ecology and management of these interesting and unusual vines. Considering the
lack of success in management of these species using traditional means of control,
possibilities for successful biocontrol options are now being rapidly explored. We
hope that the information we have generated regarding the ability of these species
to spread and reproduce, and exhibit allelopathic interference may lend itself to the
successful development of biocontrol strategies before further uncontrolled spread
occurs.
