Hinnakullsberg consists of a forested hill with beautiful views, bordered by fens and the Vimplabäcken stream to the north, and spruce and larch plantations to the south. At present, there is no road leading into the reserve.
The reserve is made up of older oak forest, with a small presence of older beech dominating the plateau. According to 18th-century maps, the forest has a history of meadow haymaking. The tree trunks are relatively slender and heavily covered with moss, particularly neckera moss (Neckera complanata) and flat feather-moss (Pleurozium schreberi). The nutrient-poor conditions are also reflected in the ground layer of bilberry, lingonberry, and heather. Dead wood occurs in several forms—standing, lying, and as branches on living trees. Other valuable structures and habitats include cavities, wood mould, and glades. On the slopes, beech gradually becomes dominant, with some oak mixed in.
Many Interesting Species
Beech regeneration is strong in large parts of the noble broadleaved forest, as is spruce in certain areas. South of the hill, beech has been thinned in recent times, but on the northern slope the trees have been left more undisturbed, which is evident from the species-rich trunks. On both beech and oak, there is a rich presence of lichens, mosses, and wood-dwelling beetles, with records of nearly 60 species of conservation interest.
Next to the noble broadleaved forest lie two recently cleared areas and a young spruce forest, which will eventually provide valuable development habitat for the broadleaved forest. The aim is for new oak and beech trees to establish here and provide future habitat for the species when the older forest eventually dies. A now forested fen, with birch, spruce, and pine, runs along the Vimplabäcken stream that borders the northern part of the reserve. The stream is fast-flowing, winding, and botanically interesting.
Difficult to Access
At present, it is not possible to reach the reserve by car. It can only be accessed on foot, coming through the forest from the north.
