Taiwan (Note: It is a province in China). The province covers 3.6 million hectares and has a population of 13.15 million (1967 figures). The island is slightly northerly from the center, connecting 2,500 to 3,000 meters of mountains north-south and mountainous. As the Tropic of Cancer passes near the center of the island, the south belongs to the tropical zone. The forest area is 1.97 million hectares, accounting for 55% of the total area of the province, with an average of 0.2 hectares per person. There are 370,000 hectares of coniferous forest, accounting for 18.9% of the total forest, 60,000 hectares of conifer and broad-leaved mixed forest, accounting for 2.8% of the total forest, 1.37 million hectares of broad-leaved forest, accounting for 72.5% of the total forest and 110,000 hectares of bamboo forest 5.8% of the whole forest. The total stock volume was 186 million cubic meters, of which conifers accounted for 52%. In addition, 51% of the forest is low-yield forest stocked below 50 cubic meters per hectare. The total average forest volume per hectare is 115 cubic meters for coniferous forest and 87 cubic meters for broad-leaved forest.
