Although these flowering plants are beautiful, they're considered an invasive species and can reek havoc on our ecosystem.

There are 68 terrestrial, wetland and aquatic plants that are banned in NYS because their introduction would likely cause economic or environmental harm or harm to our health as well as threaten New York’s food supply.

The regulations are enforced by the Department of Environmental Conservation, with assistance from the Department of Agriculture and Markets.

Lonicera tatarica is a species of honeysuckle known by the common name Tartarian honeysuckle. It is native to Siberia and other parts of eastern Asia, but it is probably better known in North America, where it is a widespread introduced species and noxious weed.

Any of these invasive species can harm natural communities and systems (plants and animals found in particular physical environments) by out-competing native species, reducing biological diversity, altering community structure and, in some cases, changing ecosystems. Invasive species threaten New York’s food supply, not only agriculture but also harvested wildlife, fish and shellfish; our landscaping, parks, gardens, and pets; and our recreation resources and even animal and human health.
