Halland's forests during the last 300 years: a review of Malmström (1939)

Abstract Carl Malmstrom's historical forest maps of the province of Halland, in south-western Sweden, were published over 70 years ago, but are still important to science and conservation. They show the transformation of a seventeenth century landscape of temperate broadleaves to a landscape dominated by open land and heather (Calluna vulgaris) in the nineteenth century, and to a landscape of coniferous forest plantations in the twentieth century. This article summarizes and reviews the original research, first published in Swedish in 1939. Malmstrom concludes that the large changes to forest abundance and composition over the last 300 years were predominantly the product of human endeavours. The most important causal factors behind the decrease in forest area until the mid-nineteenth century were the incentives to increase arable land and meadows, the grazing and burning of Calluna heaths, and logging for timber, fencing and firewood. The subsequent increase in forest abundance after this period were due...
