Abstract
Natural browse use by white-tailed deer (Odocoileusvirginianusborealis Miller) was measured in the fall of two consecutive years using captive animals in enclosures located in regenerative stands. Oven dry twig weight prediction equations were first established for each species in the area, and browse use measured weekly by counting the number of twigs removed. Average daily browse use amounted to 0.75 kg for fawns and to 0.80 kg for adults. Shadbush (Amelanchier spp.) and willow (Salix spp.) were highly preferred by the fawns; lambkill (Kalmiaangustifolia L.), red maple (Acerrubrum L.), and withe-rod (Viburnumcassinoides L.) were preferred by the adults. A shift towards use of conifers by fawns was observed in relation with the appearance of snow. No discernible lasting damage to regeneration of commercial species was noticed even at a browsing pressure evaluated at 2–3 times the normal level.
