Invasive Species Removal Committee

(ISRC) This program is designed to

control the spread of the invasive species Water

Chestnuts (Trapa natans L.). The program is designed to

eliminate this species from our waterways in the North East of

the United States by teaching boaters how to properly

remove the species. By: Kaitlin Byrnes

In our community there is a large infestation of chestnuts (Trapa natans) in our water ways in the United States. The rate is currently 300 acres of water chestnuts that cover 55 miles on most lakes which prevents boaters from passing and kills wildlife. We would like to see this number decrease to 100 acres across the 55 miles. This problem is a result of not removing the species properly, resulting in the grow in population.

Americans who use the northeast water ways as means of transportation or recreational use will participate in Better form of removal of this species of plant. A program that teaches how to pull from the roots.

the outputs will be a monthly count of how many Americans who use the northeast water ways as means of transportation or recreational use. sign up for and participate in the program

We would see the number of boaters able to demonstrate the correct way to remove water chestnuts will be higher.

The number of water chestnuts will be lower in places where people participate as compared to those not participating.

The community problem of water chestnuts in our water ways in New York State will decrease overtime.

HORVATH For these species and others not mentioned, recreational boating is by

far the most probable vector of initial introductions into watersheds STRAYER

In addition to these ecological effects, water-chestnut is regarded as a serious nuisance because its dense stands prevent recreational use of hundreds of hectares of shallow-water habitat and block access to the river channel from the shore.

HUMMEL & KIVIAT Water chestnut is capable of covering nearly 100% of the water surface when

conditions are favorable. Water Chestnuts interfere with boating, fishing, swimming, duck

hunting, and other beach-related activities are also hindered by the sharp nut hulls that accumulate on shores and cause painful injuries when stepped on, sometimes penetrating shoes.
