Orange County, NY Landscaping Rules: Native Plants (2026)

Invasive species are non-native species that can cause harm to the environment, the economy or human health. Invasives come from all around the world. As international trade increases, so does the rate of invasive species introductions. Invasive species threaten nearly every aspect of our world and are one of the greatest threats to New York's biodiversity. They cause or contribute to: Habitat degradation and loss; The loss of native fish, wildlife and tree species; The loss of recreational opportunities and income; Crop damage; Diseases in humans and livestock; and Risks to public safety. Terrestrial invasive species are land-living organisms that negatively impact our communities, fields and forests. They can decrease our enjoyment of nature, increase the cost of living, and even put our health at risk. Aquatic invasive species can be introduced and spread in a variety of ways. Some are spread via home aquariums and water gardens. Others can be spread by boaters and anglers who do not properly clean, drain, and dry their boating and fishing equipment. Preventing the spread of invasive species is important to protect and restore New York's healthy ecosystems. To combat the impacts of invasive species, DEC created and supports the Bureau of Invasive Species and Ecosystem Health (BISEH) within the Division of Lands and Forests. This group works across the state by providing expertise, assistance and action where invasive species are a threat. BISEH collaborates with numerous stakeholders including State and Federal agencies, non-governmental organizations, industry and notably through Partnerships for Regional Invasive Species Management (PRISMs).
