During the years 1976-86 predators killed a total of 11 295 reindeer in the Finnish reindeer husbandry area. Predators killed mostly calves and hinds. With the exception of the Kåsivarsi and Muotkatun-turi reindeer herding cooperatives, kills of predators were concentrated in the reindeer herding areas on the eastern border. During 1976-86 predators killed most reindeer in April - June, and the majority of preys were calves. Most reindeer were killed by wolves (26.9%), bears (24.7%), wolverines (22.6%) and eagles (15.9%). Wolves, bears, wolverines and lynxes killed mainly adult reindeer, eagles killed mainly calves. Wolves killed reindeer mainly during October - January, lynxes during January - April, wolverines during February - April, eagles during May - July and bears during May - October. During the last years the number of reindeer killed by lynxes has increased in Finland.
