National Invasive Species Awareness Week 2013
by Laurie Sheldon History and Definition President Bill Clinton On Feb 3, 1999, President Bill Clinton signed Executive Order 13112 - a critical piece of legislature on the environmental front. It established a multi-agency task force (the National Invasive Species Council) to deal with the management of " invasive species ," which it defined as a species: that is both non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health. These "invaders" present themselves in many forms, and include (but are not limited to) plants, animals, and pathogens. I found an air potato as big as my hand at a Roundup during NISAW 2012: air potato has been listed as one of Florida’s most invasive plant species since 1993. Causing Harm Invasives may feed on fish and wildlife and/or cause widespread illness. Invasive pathogens can kill forest trees.
