Alpine Flowers and Wildlife

The vast difference in elevation between valley bed and mountain summit, ranging from 800m to 4000m, coupled with oceanic influences in the north and west, and those of the Mediterranean from the south, are part responsible for the diverse flora of the Oisans region. The fact that crystalline and metamorphic rocks (granite and gneiss) dominate in the north and west, and sedimentary rocks such as limestone, schist and clay are found in the south and east, also plays a major part in the region's rich diversity. According to national park literature some 1800 species (representing half of all French flora) have been identified, 800 of which are protected by law, while around 40 species are considered either rare or endangered, and 35 noted for being endemic to the area.
