County of Kalmar, Öland (56° N, 16° E)
In February 2012 we marked 25 moose on the island Öland in Southern Sweden of which five moose were males. Öland is very special – in none area of our research projects, moose home range include so much arable land (> 50 %) than on Öland. Like other areas in southern Sweden, the island is free from natural large predator. Yet, local observations recorded unusual low summer survival of calves-of-the-year. To study this observation and to be able to follow calf summer survival more closely, we marked and weighted parts of the calves-of-the-year. To compare the calf summer survival on Öland with corresponding calf survival in other areas in Southern Sweden (which are free from large predators), we also marked parts of the calves-of-the-year in the reference areas around Växjö and at Öster Malma. Our results confirmed a low summer survival on Öland as suggested by local observations. Moreover, our results show that the island has a remarkable low summer survival of moose calves, which is in fact the lowest ever recorded world-wide for an area with large predators. By the end of 2017, 37 adult moose (30 cows, 7 bulls) have been marked on Öland, and we have been able to document the birth and survival of 106 calves.
