Intervale Lowlands is a 135 acre private nature preserve in Lake Placid, NY along the West Branch of the Ausable River. It is comprised of forested areas, grasslands, wetlands, and aquatic habitats that support more than 150 species of birds, including rare forest breeding raptors. Intervale Lowlands has been preserved by Nancy and Larry Master through a conservation easement held by the Lake Placid Land Conservancy. Intervale Lowlands aims to partner with local and regional nature centers, conservation organizations, universities, and individuals through education, outreach, and scientific research.
