Marsh Thistle
Marsh thistle grows in wet meadows, swamps and bogs. It blooms in June through August and can grow to be 2 metres tall. The stem and the leaves have many small thorns. In the photo of marsh thistle is the Black Veined White butterfly.


Globe Flower
When cattle or horses graze on the meadows and the meadows are neither drained off, fertilized, or sprayed, there is a myriad of life with butterflies, flowers and birds. The globe flower is completely dependent on the grazing, as their habitats would otherwise become overgrown with willow and brush. Below Lien there are still areas with many globe flowers.


Water avens
Water avens belong to the rose family like meadowsweet. It grows near streams and in meadows. It is a good nectar plant for bees and flowers from May until June.


Meadowsweet grows densely along streams and in wet marshes. The flowers have no nectar, but are pollinated by pollen-collecting insects. The flowers can be used for seasoning in mead, which is a fermented honey wine, and the dried flowers and leaves for herbal tea.

Jew's ear
This brown ear-shaped fungus grows especially on elder trees close to the sea. Jew's ear is gelatinous and is edible.

The bushes can grow to be 5-6 metres tall. It is only the female plants, which bear fruit. The sour orange berries have a high vitamin C content and can be used for schnapps, jams and juices.

Guelder rose
Guelder rose bushes can grow to be 5 metres tall. They blooms in June with large flat white flower clusters. In late summer, you can see the beautiful red poisonous berries. Perhaps this is where the Danish name (kvalkved) comes from. In Danish the words kværke, kvæle and kvalme mean strangle, suffocate and sickness. If you eat the poisonous fruits, you will become sick.

Giant hogweed
Giant hogweed has been registered in this area. It is an undesirable plant, which is not native to the Danish flora. It is originally from the Caucasus Mountains and came to Denmark as a garden plant in the late 1800s. The plant is a problem, since it spreads fiercely in nature and drives out all other plant species. Avoid touching the plant, since the sap gives serious skin damages. 

In Jammerbugt Municipality there is a plan to control this plant. The owners of areas with giant hogweed are instructed to fight off the plant. If you see a giant hogweed, you should inform the municipality. On the municipal website www.jammerbugt.dk there is guidance on how to get rid of the plant.

The landscape
The most characteristic elements in the landscape are the coastal cliffs from the Littorina Sea era (the geological brackish-water stage of the Baltic Sea), gaps from erosion and formation of marshlands. The most dominant landscape element is the 7 km long Lien cliff, which is Denmark's tallest coastal cliff. The cliff formed the coastline until around the year 0. During the Littornia Sea era, the Lien cliff was a bare clay cliff with many erosion ravines, which today form the forest-covered valleys, Langdale Valley, Fosdale Valley, Nøddedale Valley and Dybdal Valley.

Below the Lien cliff there is a large continuous dune landscape with heather and grassy inland dunes.

Natura 2000 area
The Lien cliff is part of the Natura 2000 area, number 21, Ejstrup dune,
Egvands Hills and Lien with Underlien.
The Natura 2000 area encompasses 2.347 hectares and consists of 2 habitats areas.

In the majority of the deep ravines on the Lien cliff wonderful springs have formed and there are fens and springs in several places at the foot of the hillside. Svenstrup stream runs below Lien. Many place on the Lien hillside itself there are valuable acidic and chalky grasslands.

The EU Habitat directive imposes Denmark to make the necessary actions to ensure or re-establish a number of rare, threatened or characteristic nature types and species. In Denmark there is a total of 246 Natura 2000 areas, of which 6 are located in Jammerbugt Municipality.

Nature preservation
Parts of the Lien cliff must remain open without trees. This is a requirement according to both the conservation provisions and the Natura 2000 plan for the area. There are no longer many of the open species rich grassy hillsides left as in past times, and that is why an effort is greatly needed.

Around 1900 large parts of the Lien hillside were grazed by livestock. Today, cutting trees and letting animals graze will be necessary for the conservation of natural habitats. The same applies for the moors and the wet areas with fens, where growth of trees and bushes also is a problem.

European badger
There is a very large badger population in the area and for this reason many badger burrows. The badger burrows can be identified from fox burrows by the deep furrows, which the badger makes, when it scrapes out soil and other material from the dwelling. The badger is distinctly nocturnal. The badger is Denmark's largest rodent and has been protected since 1994.

Red fox
The fox is nature's garbage man. It cleans up and eat carrion in the wild. However, the main diet of the fox consists of mice and birds. In the summer and autumn the fox eats many earthworms, insects and berries. There is a hunting season on foxes.

European adder
Denmark's only poisonous snake. It can be seen in places warmed by the sun in April and May, when it has just emerged from hibernation. Males are usually grey with black zig zag stripes and females are brown with dark red/brown zig zag stripes. The adder is protected as are all reptiles. See www.naturcenterfosdalen.dk.

In Denmark there are 4 species of deer: Red deer, fallow deer, sika deer and roe deer.

Alll of the species can be found in this area except for sika. In nature, the deer are diurnal, but due to human activity, they usually remain hidden during the day. The red deer is the largest wild mammal in Denmark. There is a hunting season on deer.

Common buzzard
In spring, you can see the migration of birds of prey, especially of buzzards, where large flocks gather on their migratory routes. The Scandinavian buzzard migrates through Denmark to their breeding grounds further north.

Buzzards make use of the thermal winds to ascend up to high altitudes without using significant energy and then glide through to the next ascending air flow.

The buzzard is Denmark's most common and most widespread bird of prey.

Meadow pipit
The meadow pipit requires open areas with low vegetation. It has its nest on the ground in a tuft of grass on salt marches or in bogs. The meadow pipit has a characteristic song, which makes a "sit sit sit" sound.

Reed warbler
The reed warbler is a lively small and brownish bird. It often hops around in reeds with its head upside down. The reed warbler's song is varied with stanzas of long cutting tones. It often sings at night.

Eurasian skylark
Is one of Denmark's most common birds only outnumbered by the blackbird and chaffinch. The skylark is an indicator of spring, where its song can almost be heard round the clock. The nest is very hard to find, since it is just a small dent in the ground lined with roots and straw.

Common cuckoo
In the beginning of May you can hear the cuckoo sing its song, and if you are lucky, you can also hear the beautiful song of the nightingale from the willow scrubs below Lien. The cuckoo and nightingale are summer guests. They both spend the winter in Africa.
