In the 1960s the government struggled to obtain foreign exchange. Under a policy of forcefully pursuing industrial development, record numbers of trees were cut. In 1960 the Yuli Forest District Office was established, and the forest compartments upstream continued to send down such top-grade conifers as red spruce and cypress and such broad-leaved trees as the Nanmu and Formosan Michelia.
民國五十年代，政府在爭取外匯，致力發展工業的經建政策下，伐木業進入顛峰期，民國四十九年玉里林管處成立，清水溪上游林班源源不絕送出紅檜、扁柏等一級針葉木和櫧木、楠木、烏心石等闊葉木。
