If you search for Taiwan on Google maps, you will soon see that it is a long-shaped island facing the Pacific Ocean to the east and the Taiwan Strait to the west. It covers a total area of 36,197 km2 with a similar land size to Switzerland in Europe.
Taiwan boasts about its high mountains with many more than 3000m in altitude, so the different forests at different altitudes and varying weather patterns come together to create many vertical distributions of terrestrial species.
The habitat environment and ecological systems in these tropical, subtropical, warm temperate, cool temperate, cold temperate, and subarctic zones of the northern hemisphere are all condensed into the mountains and forests on the island, which is a rare phenomenon compared to other areas around the world. Due to the influences of the landform, latitude, monsoons and ocean currents, Taiwan allows people to experience dramatically changing weather in the blink of an eye, in addition to the forests and ecological changes. Therefore, no matter whether it is the mountain area or plains, South or North, West or East, all possess very different weather features; either through rainfall patterns or temperature changes.
As the temperature decreases about 6°C with each rise in altitude of 1,000m, the temperature in Yushan peak, at an altitude of 3,952m, always remains at around 10°C, while the temperature on the plains is around 30°C in the summer. The air pressure will decrease inversely as the height increases, as will the concentration of oxygen in the air. Therefore, the weather in the high mountains is not as pleasant or predictable as it is on the plains. Please do check the weather conditions in National Forest Recreation Areas before you start out. To enjoy a happy trip up the mountains and in the forests, you must not ignore climate influences!
