Switzerland contains numerous tree species including beech, oak, larch, hornbeam, spruce and chestnut, according to Encyclopaedia Britannica. Alpine vegetation grows above the tree line, as does that of a tundra biome. Four distinct climate regions affect where different kinds of trees live in the country. Switzerland has more than 50,000 plant and animal species, including 30,000 insects and 83 mammals.
Beech and oak trees thrive in the maritime west climate of Switzerland, and hornbeam and larch trees dominate the continental eastern part of the country. Spruce trees grow in the subalpine region in the north, while chestnut groves are mainly in southern Switzerland. Alpine boundaries are several hundred feet higher in the south due to warmer climates and more direct sunlight. Tundra is susceptible to erosion from skiing throughout Switzerland.
The Noah Project contains photographs of more than 70 plants and flowers of Switzerland. Among them are wildflowers, grape vines and alpine trees. The aim of the website is to catalog as much plant life in various countries as possible.
Nearly 10 percent of Switzerland's plants are species not native to the country. Of those non-native species, one in 10 is invasive. The Swiss Commission for Wild Plant Conservation is responsible for monitoring and controlling invasive plants.
