An "invasive species" is defined as a species that is: 1) non-native (or alien) to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health. Invasive species can be plants, animals, and other organisms (e.g., microbes).
When an invasive species is introduced into an area, there are often no predators or biological factors present to keep population numbers or growth in check. This can wreak havoc for native landscapes and species, destroying biodiversity and disrupting ecosystem processes. They can even cause problems in our own yards and gardens. Some plants, like Giant Hogweed, can also be toxic to the health of humans. It is important that residents of Sullivan County are aware of these invasive species so we don’t inadvertently spread them, and so that we can report their presence to managing organizations.
