|| With many mountains, Taiwan has abundant timber. The Taiwan Forest Bureau, in charge of the national forest land, is responsible for the planting, protection, and logging of forests. The annual production of forest products, including plywood, reaches an average of about 1,200,000 cubic yards, exclusive of firewood. Fishery production has increased to over 650,000 tons annually. About 12 percent of this are produced by fish farming. The balance is caught in rivers and in coastal water. The warm currents in the Pacific Ocean off the east coast provide good deep-sea fishing grounds, especially for tuna. The Taiwan Fishery Bureau was established to help develop the fishing industry, and the number of fishing vessels also increase.
