Verification of food supply for red deer under conditions of the airpolluted area of mountain forest ecosystems in the ore mountains (Forest District Klášterec nad ohří)

Abstract

On the basis of typological classification, representative sample plots 1×1 m were established in forest stands, on meadows and pastures in hunting districts Jelení hora and Černacute; potok in the area of the Ore Mountains (Forest District Klášterec nad Ohří) in the growing season. The aim of the plots was to determine the existing average area production (kg.m-2) of biomass utilizable by game. The biomass was diff erentiated to herb, grass and woody components. Analyses proved that the total daily need of food, energy and mineral substances of red deer in both hunting grounds was fully covered by the natural food off er of herb, grass and woody biomass in the growing season even in case of increased requirements, e.g. in the period of growth, lactation or the development of antlers.
