Oaks, elms, firs, ashes and beeches are the principal forest trees.
On the mountains the trees are chiefly pines, firs, spruce and hemlock.
The chestnut covers considerable areas in Prigord, Limousin and Beam; resinotis trees (firs, pines, larches, &c.) form fine forests in the Vosges and The indigenous fauna include the bear, now very rare but still found in the Alps and Pyrenees, the wolf, harbouring chiefly in the Cvennes and Vosges, but in continually decreasing areas; the fox, marten, badger, weasel, otter, the beaver in the extreme south of the Rhne valley, and in the Alps the marmot; the red deer and roe deer are preserved in many of the forests, and the wild boar is found in several districts; the chamois and wild goat survive in the Pyrenees and Alps.
High districts covered with oaks and chestnuts succeed to this almost tropical vegetation; a little higher up and we reach the elevated regions of the Pollino and the Sila, covered with firs and pines, and affording rich pastures even in the midst of summer, when heavy dews and light frosts succeed each other in July and August, and snow begins to appear at the end of September or early in October.
Witches-brooms are the tufted bunches of twigs found on silver firs, birches and other trees, and often present resemblances to birds nests or clumps of mistletoe if only seen from a distance.
