Gribskov (Grib Forest) is Denmarks fourth largest forest,[1] comprising c. 5,600 ha of woodland situated in northern Zealand, west and south of Lake Esrum. The forest is owned and administered by the State of Denmark.

Gribskov is usually divided into four sections: The northwest surrounding the small village of Maarum, the northeast on the banks of Lake Esrum, the southwest around the small lake of Gribsø and finally the southeast, enclosing the village of Nødebo on the southern banks of Lake Esrum.

Gribskov is separated by only a thin strip of Hillerød town in the south, from many larger woodlands like Store Dyrehave at 1,100 ha, Tokkekøb Hegn at 631 ha and several smaller woods.[2][3]

Ethymology

The Danish name Gribskov, literally translates to Grib-forest in English. The first part 'grib', directly translates as catch! and grab! in English,[4] but the actual meaning and ethymology of the word, goes a bit deeper. 'Grib' refers to the Old Danish word for something 'without any specific owner' so Gribskov means a woodland of common ownership so to speak.[5]

Nature

Gribskov and Lake Esrum, is designated as EU habitat directive and Natura 2000 areas, as part of an even larger protection.[6] On top of that, Gribskov is designated as an Important Bird Area (IBA). Around 20% or c. 1,200 ha of the forest has been reserved as 'forest to be untouched', in an effort to preserve some of the few spots of semi-natural woodland (SNW) in Denmark and stimulate the growth of new.

The birdlife in Gribskov is varied and of international importance. The forests is home to the largest populations of Common Goldeneye, Green Sandpiper and Red-backed Shrike in Denmark[7] and near Nødebo at Lake Esrum, a noisy colony of great cormorants have found a home.

The forest is growing in a hilly terrain (by Danish standards), with lower lying areas in the east and west. The low lying areas are dominated by beech and oak, but with several forest types mixed in, like wood pastures or old coppice woodland with alder and ash for example. The curved terrain create a lot of small ponds, bogs and swamps and exposes quite a lot of springs, some enshrouded by myths, superstition or old folk tales.[7]

Gribskov is more than 10,000 years old, dating from the end of the last ice age,[8] but the forest bear the marks of an intensive plantation industry, that accelerated from the late part of the 1700s and peaked in the 1800s. Many new tree species where introduced to the wood, former wetlands where drained and planted with trees, especially European spruce. These practises are now dismantled in Gribskov, the spruce plantations are cut down, ditches are being filled to allow a more natural waterflow and it is believed to be naturally and quickly replaced by an alder, birch and willow habitat in coming years. It is expected that Gribskov will comprise more semi-natural woodland of deciduous trees in the future.

The forest of Gribskov offers a rare opportunity to observe free roaming deer of all the four species living in Denmark. This includes the roe deer, sika deer, red deer and fallow deer, with roe and fallow deers as the most common in Gribskov. Roe deer have been living here for as long as the forest itself, while the fallow deers was introduced at some point during the middle ages. The fallow deer population in Gribskov, is the largest free roaming fallow deer population in Denmark, at 600-800 animals.

Lakes, ponds and wetlands

There had been a long tradition for draining by digging ditches and regulating the natural waterflow in the forest for various reasons, but these practises are now been dismantled and work is in progress to re-establish a more natural waterflow and improving conditions for wetland areas.[9] This has already bettered the biological diversity and have had a direct positive influence on the living conditions of the birds in Gribskov. There are several interesting bodies of water in Gribskov, seen from both a scientific and folkloristic viewpoint:

Store Gribsø (English: Large Grib-lake) or just Gribsø, is only a 10 ha lake, but is nevertheless the largest lake enclosed by Gribskov. It is a so-called dystrophic lake and it is impossible to see the bottom in its dark waters, even though it is only 11 m deep. The lake have no outflows and it can be ice cold just beneath the surface, so bathing should be done with care. Tradition says the lake is bottomless and was created, when God angrily punished a nun monastery that once was here. The nuns showed more interest in the monks at Esrum Abbey than in God, so he opened up the ground and the chasm swallowed up all the nuns and the entire monastery. The monastery continued to sink and sink and that was how the lake was created. It is said that one can still hear the monastrys' bells ringing down in the lake on quite evenings.

Landmarks and structures

There are many small ponds, streams and lakes throughout Gribskov, but the larger ones are 'Store Gribsø', 'Solbjerg Engsø' and 'Strødam Engsø' all in the southeastern parts. The latter two are the largest and attracts a rich birdlife, but they are both situated on the edge of the forest.

The most prominent landmark is perhaps 'Svenskegrøften' (English: The Swedish Ditch) initiated in 1576. It is a 2–3 km long artificial canal, winding its way through the forest from the lake of Store Gribsø and south towards the settlement of Gadevang in the southeastern section. As the name implies, Swedish prisoners of war, was used for this large project ordered by King Frederik II. The ditch is just a part of a bigger network of ditches, dug since the middle ages to supply the Frederiksborg Palace with running water, to exploit the water ressource for the watermills of earlier times and to drain the wetlands so the land could be used for plantations. There is an estimated 526 km of artificial ditches in Gribskov.[9]

Pre-history

There are several relics of the past in Gribskov. An example is the megalithic passage grave just outside Kagerup, a village south of Maarum in the northwest of the forest. It was raised at some point in the neolithic Stone Age, about 5-6,000 years ago and is referred to as 'Jættestuen', simply meaning The Passage Grave in English.[10] Not far from the megalithic tomb, is two round dolmens, one of which is heavily deteriorated though. Another megalithic passage grave is situated in the southwestern parts of the woods. This tomb is of similar age and origin as 'Jættestuen', but is called 'Mor Gribs Hule' (English: Mother Gribs Lair). Tradition says that the notorious sorceress Mother Grib had residence in the grave chamber. She used to whistle at the wayfaring, leading them astray and then her sons killed and robbed them, when they lost their whereabouts in the woods.[11] This story gives an entirely new meaning to the name of Gribskov.

Just northwest of Gribskov, the small woodland of 'Valby Hegn' holds a total of seven long barrows from the neolithic.

Buildings

Gribskov is cut through by 'Gribskovbanen', an old railway line laid out in 1878, then offering the urban population a first-time opportunity to visit the forests.

Near the village of Nødebo at Lake Esrum in the southeastern part of the forest is 'Skovskolen' (English: The Forest School), a large school situated in the old foresters lodge 'Skovfryd' (English: Forest-joy) from 1829-30. Here forest engineers, landscape engineers and nature guides are educated.

In the northeastern corner is the old Esrum Abbey.

  • Entrance to the Stone Age passage grave of 'Mor Gribs Hule'.

  • The old Esrom Monastery from c. 1140.

  • Mårum train station in the northwestern section of Gribskov.

Forestry and hunting

Gribskov have a long tradition for forestry of all kinds.

In 1736, the German forester Johann Georg von Langen participated in restoring the Danish woodlands of the time, by introducing European Larch. Some of the first larch trees where planted in Gribskov in 1776 and they can still be seen here today in the northwestern parts, just east of Mårum. They are known as 'Tinghuslærkene' (English: The Tinghus-larches). One of those trees, now marked with a yellow ring and standing 36 m tall, was eventually picked in 1935 by the Danish forestry-genetic Carl Syrach-Larsen for hybrid experimentation. From the marked tree in Gribskov, he developed a very successful hybrid with Japanese Larch, able to withstand the devastating fungal larch canker disease also known as Lachnellula willkommii. The hybrids also had a faster and healthier growth. The hybrid is known as Larix × marschlinsii or L. × eurolepis (discouraged name) and can also occur spontaneously wherever European and Japanese larch grows together.

Nowadays parts of Gribskov are used for seed-production of species like European spruce.

The history of hunting in Gribskov is also reaching far back in time. The most visible signs are perhaps the extensive path structures laid out in different parts of the forests, especially near Nødebo in the years 1680-90 by King Christian V. Long straight lines, usually designed in star-patterns, merging and radiating from strategical points. They were constructed and used for running up and tiring the game (usually deer) in so-called parforce hunting, by horse and packs of hunting dogs. The same kind of outlay and design can also be seen in the nearby woodlands of Store Dyrehave and Jægersborg Dyrehave, just south of Gribskov. They are all former royal game reserves. Gribskov is still used for hunting nowadays - in particular deer - and some areas are not to be disturbed, but parforce hunting is illegal and has been since the year 1777.
