 "Hind forests" and "stag forests" are so called because of the tendencies of red deer to form large, single-sex herds outside the autumn rutting time, and most forests hold either a resident stag herd or a hind herd for much of the year.In "deer forest", the term "forest" is derived from the ancient and medieval use of the Latin word "foris" - "open" or "waste", to denote an extensive outdoor "waste area" kept as a hunting preserve.Scotland's deer forests are almost all privately owned and managed, although a few once-distinguished forests such as Torridon and Glenfeshie have moved into semi-public ownership via bodies such as the National Trust for Scotland, the Royal Society for the Protection of Birds and the Ministry of Defence, and sporting deer stalking is no longer carried on there.
