NEWS & UPDATES
Integrated pest management (IPM) involves using both pesticides and biological controls to combat invasive species. It can be difficult to use in some cases because the pesticide can impact the biological control population as much as that of the invasive species. Until recently, the impacts of insecticides on Laricobius nigrinus, the biological control of choice in New York, was under question.
New research from Georgia reveals that using an integrated chemical and biological approach for combating hemlock woolly adelgid can result in better hemlock health and a reduction in adelgid numbers without greatly impacting Laricobius populations.
Feral Swine Legislation
October 21, 2013
Gov. Andrew Cuomo signed into law legislation prohibiting the importation, possession, sale or release of Eurasian boar, wild pigs and their hybrids. The law phases out high-fenced shooting enclosures and breeders from these animals by 2015, and immediately prohibits importation or release of the animal. Violators would fined $500 to more than $1,000.
A. 3767/S. 5733, sponsored by Assemblymember Deborah Glick, D-New York, and Sen.Betty Little, R-Queensbury, was supported by The Catskill Center and The Catskill REgional Invasive Species Partnership (CRISP) due to concerns about the impacts of feral swine on native wildlife populations and agriculture.
Aquatic Invasive Discovered in Cayuga Lake
September 5, 2013:
The aggressive aquatic plant Water thyme, Hydrilla verticillata, was found last week in Cayuga Lake. Hailing from Asia, many scientists consider Water thyme the most problematic of all aquatic invasive plants. In favorable conditions, the plant is capable of growing an inch a day, smothering native plant species and clogging waterways.
Water thyme tolerates a range of growing conditions and can inhabit water from a few inches deep to thirty feet in depth. Although the plant prefers slow moving water, it has recently been found in the fast moving waters of Fall Creek, also in Cayuga County. Its recent foothold in Cayuga Lake makes it unlikely Water thyme will be exterminated in New York since Cayuga Lake holds too much water for known eradication measures.
Introduced by the aquarium trade in Florida in the 1960s, Water thyme currently is present in numerous states including Connecticut, Massachusetts, and of course, New York. This most recent find in Cayuga Lake highlights the importance of early detection and rapid response reporting when it comes to preventing invasive species from taking over our waterways. If detected early, invasive species are controllable and management costs can be kept low.
