Logging of Infested Pine and Nematode Control in Zhongshan Forest, Kinmen National Park
To eliminate the pine wilt nematode (PWN) pest infestation in the Zhongshan Forest, Kinmen National Park Administration (KNPA) began logging infested pine trees in 2015 and has so far removed over 1,000 trees. In the interests of of long-term forestry management and maintaining ecological balance, the KNP Zhongshan Memorial Forest and Taiwu Mountain Pine Tree Survey and Seminar was held in December, 2015 and March 30, 2016. Numerous scholars were invited to provide assistance by proposing prevention and control measures, including Professor Shean-Shong Tzean of the Department of Plant Pathology and Microbiology, National Taiwan University (expert in plant pathology); Professor Chyi-Rong Chiou of the School of Forestry and Resource Conservation, National Taiwan University (expert in forestry management); Researcher Chau-Chin Hung of the Taiwan Agricultural Chemicals and Toxic Substance Research Institute, Council of Agriculture, Executive Yuan (expert in insect pheromones, plant protection, and entomology); and Professor Ching-Yuh Chen of the Department of Applied Chemistry, National Chiayi University.
Measures recommend by the experts include establishment of a PWN damage and prevention surveillance system; investigating the nematode fauna; and surveying vector insect types in the area and designing Japanese pine sawyer traps, which are to be used in conjunction with pine sawyer pheromones and other biological control methods.
KNPA has indicated that the spread of PWN has caused rapid infestation among pine trees in the Zhongshan Forest. To prevent continuous transmissions, applications will be made to the fire department for a prescribed burn after logging, scheduled to be completed before June. With regard to the resultant air pollution and damage to certain facilities, KNPA will request speedy restorations by service providers as soon as the assignment comes to an end. We apologize for any inconveniences that may be incurred.
