Differences in altitudes, precipitous cliffs, and plunging valleys in the Yushan National Park lend to the park highly unstable weather conditions. Temperatures can vary from warm to cold at the same time at places relatively close. While accounting for merely 3% of Taiwan's total land area, the park has half of Taiwan's native plant species growing within its boundaries. In surveys, there are 2,522 different kinds of plants found in the park.
