sure some non-native species pose no real threat....elsewhere! here in florida we are plagued with some of the worst species around...both plant and animal. plants that cause harm to water ways and choke out native speices: Brazilian Pepper, Austrialian Pine, Water Hydrilla, water hyacinth, animals causing declines in local animal populations Cuban tree frog, Cane toad, green mussel, Titan acorn barnacle, lion fish (not yet shown to be negative but just wait). here is a list from USDA of all of the florida non-native speices minus the insects two of which are causing harm are the african honey bee and the fire ant (http://nas.er.usgs.gov/queries/Speci...thway=&Sortby=[Group],Genus,Species,SubSpecies&Size=50&nativeexotic=&HUCNumber=&Page=1)

some introduced species can be benifical, however, in FL these animals get out of control and begin taking over are replacing native animals. this is never good...no way, no how. it is not beneficial...ever. florida's unique ecosystem offers a good enviorment for exotics to gain a foot hold. you cannot compare this state to anyother. we do not need any more insvasive and those that are here need to be irracated.

my comments were directed at the person who suggested that true invasive species should not be killed, even when negative impacts are determined and they should be allowed to creat a niche for themselves.
