The white-tailed deer is a common deer species on mainland America. From there it has been introduced to other parts of the world. The first white-tailed deer were introduced to Finland in the 1930’s. Today the estimated amount of the white-tailed deer population in Finland is about 30 000, and it breeds mostly in southern and south-western parts of Finland. The white-tailed deer prefers edges of forests and fields as its habitat, eating grass plants and sprouts and leaves of bushes and trees. In the winter they feed on spruce and pine needles, blueberry shoots and other twigs and soft branches. The white-tailed deer dam and calves form herds in the winter, but the males, after the mating season, prefer solitary wandering.
The white-tailed deer is a game animal. The annual quarry is 20 000-22 000 individuals.
ADAPTING TO THE WINTER
The white-tailed deer has adapted well to the arctic winter environment. At the end of the summer they increase their subcutaneous fat reserves. The white-tailed deer is known to fast even for two weeks during the harshest winter, moving as little as possible to save energy. In extreme snow conditions they may have hard time surviving though; 50cm deep snow is the limit for their survival: digging up shoots becomes ever more difficult with thick snow covering. The wintry game feeding, provided by kind humans in Finland, helps them to survive over the harshest winter times.
