Variation in climate and altitude produces a varied flora and fauna. In the lowest zone (below 550 m/1,800 ft), chestnut, walnut, cypress, and palm trees grow, as well as figs, oranges, and almonds; up to 1,200 m (3,940 ft), forests of beech, maple, and oak; around 1,680 m (5,500 ft), fir and pine; around 2,130 m (7,000 ft), rhododendron, larches, dwarf and cembra pine, and whortleberries; and above the snow line, more than 100 species of flowering plants, including the edelweiss. Wild animals include the chamois, boar, deer, otter, and fox. There are large birds of prey, as well as snipe, heath cock, and cuckoo. Lakes and rivers teem with fish.
