Consequently, deer density can reach extremely high levels, with total deer numbers in the UK thought to be at a 1,000-year high. While it may not have the same speed, it is extremely powerful. White-tail deer have proliferated because of the decline of their natural predators. Predators include wolves and lynxes, however as these species no longer exist in Britain they have very few natural predators. Roe deer are short-winded runners and expert hiders in thickets. Lyme disease is the most prevalent vector-borne disease in North America, and both the annual incidence and geographic range are increasing. Dogs are one of the only animals that cause harm to populations in Britain. Scottish roe deer were introduced to the Lissadell Estate in Co. Sligo in Ireland around 1870 by Sir Henry Gore-Booth, Bt.

Predators & Threats. Roe deer have a very unusual reproduction biology, based on using the vegetation pulse of summer to pay directly for the high cost of rutting. Roe deer, (genus Capreolus), also called roebuck, small, graceful Eurasian deer of the family Cervidae (order Artiodactyla).There are two species of roe deer: the European, or western, roe deer (Capreolus capreolus) and the larger Siberian roe deer (C. pygargus).Despite their Old World distribution, roe deer are more closely related to New World deer than to Old World deer. Other predators such as foxes, feral pigs, domestic dogs and alligators kill deer infrequently and do not pose a serious threat to deer popula-tions. At one time, wolves and the large cats ate them. 2010). Roe deer are increasingly seen in towns and cities, as they only need a tiny amount of cover – some even live close to Glasgow city centre. One of the deadliest predators of deer is the Grizzly Bear. Because roe deer have no avian predators (except very occasional kills by the golden eagle; Aquila chryseatos) canopy cover will not hide them and hence ground cover is more important with respect to predators. Habitat use by roe deer (Capreolus capreolus) under the predation risk of lynx (Lynx lynx) and humans: A life in the squeeze between two contrasting predators Jørgen Kvernhaugen Norum Master of Science Thesis 2014 Center for Ecological and Evolutionary Synthesis Department of Biosciences University of Oslo, Norway . The roe deer density in our study area was never below 2.7 roe deer per km 2 while the strong decline in kill rate in the Norwegian study occurred at a density below 1 roe deer per km 2, and the asymptote for the Type II response in Nilsen et al.
