Lauwersmeer National Park

Highlight • Natural Monument

Geography

The Lauwerszee, an inlet named after the river Lauwers, used to be open to the Wadden Sea. After the storm surge of 1953, fears of flooding led to plans for a dam, which was completed in 1969. The inlet became a closed lake, now called the Lauwersmeer, and the higher seabed (the former mudflats) was drained. The reclaimed land was left completely to itself for the first few years, so that the flora and fauna typical of the area could establish themselves.

The area has a predominantly open character, although there is a forest called the Ballastplaatbos near Lauwersoog and the Zomerhuisbos forest area to the south near Dokkumer Nieuwe Zijlen. Larger areas of the park are not accessible to the public, while the lake is also open to boats in its deeper areas. The shallow lakes and wetlands may not be entered for reasons of landscape protection.

Titled Dark Sky Park, Lauwersmeer National Park is one of the darkest places on earth. Here you can experience nature in complete darkness. There are only 41 of these parks in the world, and in this way the darkness is maintained so that nature is not disturbed. Many animals depend on the darkness that should normally exist at night. Truly dark places are becoming increasingly rare due to increasing nighttime lighting in the West.
A perfect reason to visit Dark Sky Park Lauwersmeer is the wonderfully clear starry sky. Since there is no light from the ground and the Wadden area is the place with the least light pollution in all of Holland, the stars are particularly easy to see here. On some days you can even admire the northern lights.

Freulevijver

Highlight • Lake

The freu pond is an old pingo ruin, bordered by birch, beech and mountain ash. The estate was built around 1880 by the Lycklama à Nijeholt family for wood production and the pond was part of the private park. The damsel enlarged the pond around 1900 and had a tea dome built so that her family and guests could linger there as well as boating.

The Blue Stone

Highlight • Natural Monument

The Blue Stone is located exactly on the border of Oudega and Nijega, east of the bridge in Nijega. The map of Smallingerland, dated 1664, is located east of Oudega, referred to as the "Blue Stone". This stone has been in the southern berm of Aldegeasterdyk since 1664, a stone like so many stones. Nothing distinguishes this stone from other similar stones or stones.
Not the shape, not the size, but the many scratches and ink around the stone in all directions attract attention. The depth of these colorings is deeper than normal, evoking not glacial scraping, but also chisels and human dishes, as stated in 'Smellingera country', the history book published in 1944.
That a cartographer also recorded the blue stone, along with specialties such as churches, monasteries and ducks, is a secret. The blue stone probably had an important place in the lives or thoughts of the Oudega people.

Pûpedobbe Pingo Ruin

Highlight • Natural Monument

The Pûpedobbe is a pingo ruin.

What is a Pingo Ruin?

When the climate warms, for example at the end of an ice age, a pingo is left with a circular lake or crater called a pingo ruin. Many pengo ruins are slowly filled with peat after the ice melts. This filling can take many thousands of years. Because a lot of pollen and seeds of plants end up in the water in pingo ruins, information about the vegetation is stored in the peat. This information can be used to reconstruct the climate that prevailed during the backfill. For this reason, pingo ruins are very popular with Quaternary geologists as climate archives. Pingo ruins can be dated using, for example, tephrochronology (based on volcanic ash found in the deposit). (Source: Wikipedia).

The Freulevijver, located in the Oude Bos between Wijnjewoude and Bakkeveen, is an idyllic and historic place. The forest was created around 1880 by the noble family Lycklama à Nijeholt as a private park and production forest. The pond was created by a dike breach of the nearby Koningdiep, and was enlarged around 1900 by Jonkvrouw Eritia Lycklama à Nijeholt. Although the original tea house and boathouse have disappeared, the location remains a beautiful spot for a picnic, with a natural gazebo that is reminiscent of the former charm of the place.

Flora and fauna The park is home to a variety of orchids, marsh marigolds and wild roses. The open areas are protected from overgrowth by grazing Scottish Highland cattle. In addition to the cattle, a population of Konik horses has also been established in the national park. The national park is an important resting place for migratory birds on their journeys. In addition to common waterfowl such as geese and ducks, rarer species such as the kingfisher or birds of prey such as sea eagles and peregrine falcons can also be observed. Flamingos have also been spotted in the national park.
