Setting the Stage for Fighting Invasives

Classroom training session for mapping invasive species

Invasive species have become an important subject in the environmental community in recent years but what exactly are they?  As defined by the National Invasive Species Council (NISC) an invasive species is an alien species whose introduction does or is likely to cause harm to human health, economics, or environmental processes (Definitions Subcommittee 2006).   Many of the common invasive plant species will enter an area and begin to compete with native species creating a monoculture that has little control on its population.  Due to situations like this it is estimated that almost $120 billion in damages and losses are created every year because of invasive species (Primentel et al. 2005).  Another startling statistic is that about 42% of the species on the Threatened or Endangered species lists are at risk primarily because of alien-invasive species (Primentel et al. 2005).  Luckily organizations like the Vermont Institute of Natural Science (VINS) are taking steps to combat the invasion of these species in order to protect the natural areas we love and cherish as a society.
Botanist Chris Mattrick leads the group in native plant identification
            This past week members from various organizations such as the US Army Corps of Engineers, Upper Connecticut Cooperative Invasive Species Management Area (UCISMA), Ottauquechee Cooperative Invasive Species Management Area (OCISMA), Vermont Institute of Natural Science (VINS), Student Conservation Association (SCA), Marsh Billings Rockefeller National Historical Park, and the Vermont chapter of The Nature Conservancy came together to do an intensive two-day workshop on invasive species found in Vermont and New Hampshire. The workshop included both classroom and field sessions, as well as guest lecturers.  Chris Mattrick, the botanist for the White Mountain National Forest’s Botany and Invasive Species program joined us to teach about native bog shrub species found in Vermont, along with the area’s tree species.  Classroom and field sessions included training with iMapInvasives software.  The workshops were a great learning opportunity for many that were new to invasives, and an excellent refresher for those well versed in the field of invasives. This group will continue to meet during the summer to work on invasive species removal and mapping projects throughout the Ottauquechee watershed.
