The paper examines the factors of the physical environment which exert remarkable influence on the conditions of game management in Southern Transdanubia, a part of Hungary particularly rich in natural values. The focus is on the the traditional lead game of hunting in Hungary red deer, whose populations – although still rather isolated in space – have showed a spectacular upswing recently. The long traditions of deer management are briefly outlined. The demands of deer for a favourable habitat are analysed and international survey methods are presented. The landscapes of Transdanubia are suitable for red deer to variable degrees. The health conditions of red deer are described by the quality of their antlers. Regional differences in antler types are presented. Climatic, vegetation and soil conditions are evaluated from the viewpoint of providing favourable red deer habitat. As an example of game management problems, Gemenc Forest is cited, a well-preserved floodplain area, which is rated excellent for big game hunting.
