of funds spent on their raising. In addition, game destroyed the same percentage of the individual fences around the seedlings, so that when the expenses of building the fences are added to the cost of raising seedlings, the resulting sum was considerable. On the other hand, 55.9 per cent of individually fenced-off poplar seedlings on an area of 39.44 hectares was destroyed by game, and so was 29.6 per cent of individually fenced-off willow seedlings on an area of 104.85 hectares. From this it can be concluded that poplar trees are more attacked by game than willow trees, uneless this was a coincidence of poplar trees having been planted in localities most haunted by game. In contrast to this, collectively fenced-off areas, i. e. where larger tracts of forest cultures and plantations were fenced-off, damage caused by game was the smallest, averaging 25.5 per cent of the number of seedlings or the amount of funds expended per hoctare on their raising. The above summary data have on orientational and instructive character for those cultivating forests and game in the same area, and concerning their balanced ratio, although our investigations were carried out in hunting-forest enterprises not in forest-hunting enterprises, where this ratio is as a rule balanced. |
