Invasive Species


Invasive species can be plants, insects, animals and/or pathogens that are not native to the geographical region in which they are currently living.  Due to extensive world wide travel opportunities and global marketing, non-native species can be unintentionally transported from one geographical region to another.

Since invasive species, generally, do not have natural enemies in their new habitat, they can cause extensive damage to the local environment. Some can also be a threat to human health, like Giant Hogweed.  Contact with this noxious weed can cause severe skin and eye irritation which could result in permanent blindness or scarring. The NYS Dept. of Environmental Conservation (DEC) has a hotline for more information: 1-845-256-3111.
