Early Detection of Invasive Species in Northeast Temperate Network Parks
In broad terms, an invasive species is an organism that has been introduced deliberately or unintentionally into an environment in which it did not evolve, is capable of establishing self-sustaining populations in "untransformed ecosystems", and is likely to cause harm to human health or the environment.
Early detection monitoring of invasive species was ranked a top priority during the Northeast Temperate Network's vital signs selection process due to the effects these organisms can have on park ecosystems. The known ecological impacts of invasive species include loss of biodiversity - especially threatened and endangered species, altered structure and composition of terrestrial and aquatic communities, and reduction in overall species diversity. it is critical to catch new populations of invasive species early in their invasion of new habitats when the chances of eradication remain high.
Early detection monitoring includes the creation of individual park early detection species lists; opportunistic surveillance monitoring of invasive plant and forest pest species by field crews, cooperators, volunteers, and resource managers on invasive species identification; and a framework of reporting and disseminating information on potential infestations.
Invasives Monitoring Along the Appalachian Trail
The A.T. poses a unique challenge among Northeast Temperate Network parks because of its length and the large number of communities through which it passes, opening it up to numerous groups of invasive exotic species. This also makes it a very difficult resource to systematically inventory. To date, several regional or limited surveys have occured along the trail, but none have systematically searched the A.T. region. Consequently, resource managers are underequipped to address this problem.
