An invasive species is a non-native plant or animal whose introduction to an ecosystem causes or is likely to cause harm to the environment, human health or the economy. There are two kinds of invasives species – aquatic and terrestrial. OCCA is in the forefront of invasive species control and eradication in Otsego County.
Aquatic invasive species are spread by recreational boaters and fishermen who unwittingly introduce mollusks or plant and animal species to clean lakes from infested ones.
In summer 2007, Otsego Lake fell victim to a damaging invasive species – the zebra mussel – whose ill effects include ecological destabilization, damage to municipal, residential, and commercial intake pipes, production of sharp shells causing injury to recreational users of the lake, and emission of unpleasant odors. Once established, elimination of this mollusk is impossible. Controlling the mussel is now our only resort. Posted on this website is information for property owners on how to control the zebra mussel population on and off shore. We have also uploaded information on how local fire departments can avoid spreading the zebra mussel to other bodies of water.

The water chestnut has a stem which extends to the surface of the water and ends in a rosette of floating, saw-toothed leaves. The plant bears a spiky fruit, which can pierce tennis shoes and thick-soled boots. In addition, water chestnuts can clog pipes, canals and waterways and adversely affect the environment by removing oxygen from the water and out competing native vegetation. OCCA has spearheaded a manual eradication effort of the water chestnut on Goodyear Lake. Click on the above link to learn more about the water chestnut and water chestnut eradication.
According to the New York State Department of Environmental Conservation website, New York's forests are under attack from numerous invasive exotic insect pests. In years past, we have been hit with chestnut blight, European gypsy moth, Dutch elm disease and beech bark disease, all with devastating results. Recently, we have discovered Asian long-horned beetles, hemlock wooly adelgids, pine shoot beetles and sirex woodwasps infesting New York's urban and rural forests and killing thousands of trees. Other, potentially devastating insect invaders such as emerald ash borer and Asian gypsy moth loom just over the horizon.
ASIAN LONG-HORNED BEETLE
The Asian long-horned beetle (ALB) may be one of the most destructive and costly invasive species to enter the United States. These insects threaten urban and suburban shade trees and recreational and forest resources valued at hundreds of billions of dollars. The beetle also could impact such industries as maple syrup production and hardwood lumber processing, nurseries and tourism.

EMERALD ASH BORER
An invasive beetle native to eastern Asia, the emerald ash borer (EAB) kills all species of ash trees in North America, and has the potential to cause severe economic and ecological damage. First detected near Detroit in 2002, it has now spread to 13 states, the District of Columbia, and two Canadian provinces. Ash mortality is 100% near Detroit and is widespread in all the affected areas. With establishment of EAB in New York State we can expect tremendous economic impacts in forests where ash is a common timber species and in urban areas where ash are frequently planted as street trees.
