Taipei, Jan. 30 (CNA) A forest fire was extinguished early Friday morning after burning about one hectare of bamboo forest in the Shibi area of Yunlin County's Gukeng Township overnight, the second such fire in the region this month. The incident occurred in a bamboo forest about 10 kilometers away from a separate bamboo forest where another fire broke out on Jan. 12 and burned approximately eight hectares of forest over four days. Although the two locations were in different mountain areas, local residents suspected both fires may have been caused by human activity. Caoling Village chief Chen Ping-tung (陳兵通) said it is currently the winter bamboo shoot harvest season, during which farmers or illegal foragers enter the mountains to collect the local delicacy. He said these individuals often light fires to keep warm in the cold mountain conditions, leaving behind embers that may have sparked the fires.
