Investigation of the Monetary Magnitudes of Damage Caused by Game to Mixed Stands of Pedunculate Oak and Field Ash Summary In this work the author presents the results of investigations into damage caused by game to young forests of pedunculate oak and field ash. carried out over a period of fifteen years. It has long been known that game causes serious damage to young forests by biting into top buds and byabrading the bark of young trees with their teeth and horns. However, before these investigations, no attempt had been made to assess such damage in terms of money. In his first two relevant works, and in this third, more complete and all- embracing one, the author has presented interesting results arived at by investigations conducted on a permanent experimental pilot, one half of which was solidly fenced-off and the other (control) was not, thus allowing deer and roe freely to move about. On the basis of a specially devised methodology of investigation and the results obtained, the author has concluded that game slows down the growth of young oak and ash trees up lo as much as 10 per cent in thickness, up to 14 per cent in height, and up to 51 per cent in termos of value. Furthermore, has findings show thai direct annual damage caused by game can amount up to close on 15,000 din ha (one hectare = 2.47 acres), and proposes to have young stands (until they reach the age of 20 or 25 years) fenced off since the costs of such fences are considerably smaller In addition, the author emphasizes that scars lelt by game on young trees considerably degrade the class of asssortments at the time of felling, particularly in the primary and final processing of oak- and ash wood, and thereby lower the price of wood. |
