2011 Aquatic Nuisance Species Survey
In partnership with SUNY Oneonta's Biological Field Station, CRISP identified aggressive high threat aquatic nuisance species. In the summer of 2011, a survey was taken of aquatic exotics found in lakes and streams of the Catskill region.

Water Chestnut(Trapa natans)
This import is not the tasty veggie you might find in your chow mein, but rather a floating rosette of spongy leaves with a nasty nut. Unchecked water chestnut plants will form a dense mat that decreases oxygen levels, restricts silt movement, and shades out native plants. This plant has only been detected in a few water bodies in the CRISP region and is relatively easy to remove. Report sightings of water chestnut right away so that efforts to control it can begin.

This diatom (single-celled algae) isn't really a plant, but it is green, grows in water and can cause a lot of problems. When it blooms in mid-summer, it creates a blanket across the bottom of cold, clear streams and deprives all bottom-dwelling critters of the oxygen they need to survive. These critters are the main food source for trout, so their absence has a serious impact on the food web.

Eurasian Watermilfoil(Myriophyllum spicatum)
This species grows in slow-moving or stagnant water, so if you have a lake or pond on or around your property, watch for this plant! This rapidly growing, submerged plant forms dense mats that prevent native plants from receiving adequate sunlight. In addition, thick mats of Eurasian watermilfoil can inhibit recreation and alter aquatic ecosystems by displacing fish habitat.
