Davey Resource Group was contracted to perform preventative treatment of potential Asian Longhorned Beetle host tree species in defined quarantine areas in New York City.
The contract was with the Animal and Plant Health Inspection Service of the U.S. Department of Agriculture (USDA APHIS) and covered seasonal treatments of approximately 60,000 potential host trees in the boroughs of Manhattan, Brooklyn, Queens and Staten Island.
The beetles were discovered in 1996 on several hardwood trees in Brooklyn. Soon thereafter, the secretary of agriculture declared an extraordinary emergency in order to combat the infestation and potential destruction of trees with regulatory and control actions. Asian Longhorned Beetles are believed to have been introduced into the United States in wood packing material in cargo shipments from Asia.
Thirty-five to 45 certified pesticide applicators and data recorders and 20 management, technical and data management staff members completed the work.
Treatment techniques included basal soil injections for the majority of trees, which included maples and elms, and trunk injections as necessary. This project required coordination with the New York City Department of Parks and Recreation and the Central Park Conservancy and access permits from the city's department of transportation, Long Island Rail Road, and other entities. Davey also was responsible for gaining access to properties including backyards, penthouse gardens, and courtyards.
