(Suwon=Yonhap News) Reporter Choe Jong-ho = Relevant authorities are conducting a detailed survey using drones in the Suwon area of Gyeonggi Province, where pine wilt disease was first detected.
According to Suwon City on the 14th, the Korea Forestry Promotion Institute has been flying drones within a 5-kilometer radius centered around an apartment in Iui-dong, Yeongtong-gu, where the first infected pine tree was found last month, to locate dead trees.
Once the drone locates the dead trees and completes the coordinates, personnel from the Suwon City Disaster Management Headquarters will be deployed in pairs to collect samples from the dead trees. These samples will then be sent to the Gyeonggi Provincial Forest Environment Research Institute for testing to determine if more pines are infected with pine wilt disease.
This work is expected to be completed by next month.
The National Institute of Forest Science is currently investigating how the pine trees were infected with pine wilt disease.
Suwon City plans to develop a disaster prevention plan based on the results of the investigation to prevent recurrence.
The infected pine trees will be removed on the 15th and will be used for research purposes at the Gyeonggi Provincial Forest Environment Research Institute.
Currently, administrative districts within a 2-kilometer radius of the pine wilt disease outbreak site have been designated as areas where the export of pine trees is prohibited, and the movement of pine trees is being controlled.
An official from Suwon City said, "The vector for pine wilt disease is mainly active from April to September, and no additional suspected trees have been reported since this period has passed." "We will definitely develop a disaster prevention plan to ensure that pine wilt disease does not recur."
Pine wilt disease is a fatal wilt disease that kills pine trees, and once infected, it cannot be cured. The disease is spread by the vector living in dead trees, which burrows into the young branches of new pine trees, penetrating the tree tissue and spreading the disease.
