Svinkløv Klitplantage is an over 100-year-old and varied conifer plantation that provides good habitats for animals, birds and insects due to its dense vegetation. Wild game is common, and patient visitors have good chances of spotting red deer.

As in other Danish coniferous forests, the birdlife is dominated by species such as coral tit, great tit, goldcrest and crossbill. In the tall fir trees you may find the northern goshawk's impressive nest. Other exciting bird species include long-eared owl, red-backed shrike, green woodpecker, european nightjar and raven. In autumn, the forest can be full of woodcocks, which roost here on their migration to the south.

Sletteå is a natural stream that passes through the plantation without regulation, and here you can find traces of otters, just as the stream is a popular wintering place for White wagtails. Due to its steep fall, the stream almost has the character of a mountain stream.

Svinklovene, which is the name of part of the dramatic landscape at Svinkløv Klitplantage, an area of ​​700 hectares owned by the state.

The view from the top of Svinklovene is not only beautiful, but also historically significant. Just south of the ridges lay an open strait called "Sløjen", and a channel that enabled trade fleets and Viking ships to pass between Limfjorden and the North Sea. The stretch could be monitored from Aggersborg, and it was navigable at least until the 13th century.

The entire flat area of ​​small lakes was once a continuous sea in the Stone Age, more than 50 meters below the plantation. The water level was then about 6 meters higher than today.

Svinkløv Klitplantage has been designated as an international area worthy of conservation and is an EU habitat area.

Kollerup Plantage stretches north of Fjerritslev town, only separated from the town by a small cottage area. Despite the fact that the plantation is not directly adjacent to the city, it nevertheless functions as a kind of urban forest for the residents of Fjerritslev.

The northern part of the area consists of open heath areas. To the west and east, the plantation borders agricultural land, and to the north lies a larger privately owned area with heath and grassland, which in turn borders Svinkløv Plantage. The northwestern part of the plantation was planted considerably later than the rest of the area.

A former coastal cliff runs through the middle of Kollerup Plantage. This coastal slope formerly marked the eastern limit of a strait that connected the Limfjord and the North Sea. To the north, the coastal slope is very conspicuous in several places, while further south it is less obvious. Here, sand drift, together with planting, has helped to soften the contour of the slope.

North of the coastal slope, Kollerup Plantage was established on raised seabed, on a sandy dune plain. Even the higher areas of the plantation are affected by sand drift, however the sand layer is limited in several places and the forest is lush and rich in biodiversity. The forest forms a remarkable part of the landscape, with peaks up to 45 meters above sea level.

The northern part of Kollerup Plantage borders the Grønnestrand area, which presents large areas with blow-off surfaces, parabolic dunes and dredging lakes along the sea.

This area has experienced significant overgrowth, but thanks to targeted municipal efforts, the dune landscape has been highlighted and sustainable care with livestock has been established. At the same time, deforestation in Kollerup Plantage contributes to emphasizing the characteristic landscape.
