The Burlo-Vardingholter Venn und Entenschlatt is a 148 hectare nature conservation area and an approx. 100 hectare FFH area in the areas of the towns of Borken and Rhede in the Borken district ( North Rhine-Westphalia ). It has the identifier BOR-001 or 4006-301.
General
The Burlo-Vardingholter Venn is a supra-regionally significant upland moor remnant , in which the moor regenerates in numerous gullies and former peat cuttings, partly over a large area. Today it again houses all development stages typical for raised bogs, including the transitional forms to the low bog, making it one of the most important bogs in the Westmünsterland . It lies directly on the state border with the Netherlands and is thus part of the former moor belt that formed a natural border between the two states and language areas from the Lower Rhine to the Emsland . It got its name from the neighboring villages of Burlo and Vardingholt . It is also called Klostervenn after the neighboring Mariengarden monastery in Burlo . On the Gelderland side, the nature reserve continues without interruption with the 67 hectare Wooldse Veen .
After the Burlo Convention , concluded in 1765 in Mariengarden Abbey , which made the border course binding, boundary stones were erected in the Venn , most of which are still in place today, but in many cases are hardly accessible in the nature reserve due to the rewetting measures. This "prince stones" from Bentheim sandstone carry on Münsterland side, the prince-bishop's coat of arms and on the Dutch side The Gelderland Löwenwappen, including the year 1766. They were the nineteenth century supplemented by "Empire stones" in which it is simple middle obelisk-shaped These stones that only are provided with a number.

As early as 1937, 77.1 hectares of the Burlo-Vardingholter Venn were declared a nature reserve. In 2001, when the Borken-Nord landscape plan came into force, the protected area was expanded to its present size, with the expansion areas being understood as development and buffer zones around the core zone of the former protected area. The Entenschlatt , which was previously under protection , a silting, flat heather pond surrounded by broken forest , was included in the total area during the expansion.
The few paths in the core zone of the German protected area may not be used during the main breeding season from March 15 to June 15. On the Dutch side, visitors can access the core area of the moor via a boardwalk leading through Wooldse Veen , which leads to a viewing platform located directly on the state border.
In the course of the expansion of the nature reserve, extensively used grassland and wet meadows were included in the area, for example in the northwest on the border with the Netherlands, in the central area at Pastors Diek and south of the so-called Hohnerbooms Kuhle . Here are some blanks for waders and meadow birds .
Two parts of the Burlo-Vardingholter Venn, totaling around 100 hectares in size, are designated as protected areas within the meaning of the Habitats Directive ( Natura 2000 -Nr. DE-4006-301).
In terms of nature , Burlo-Vardingholter Venn and Entenschlatt no longer belong to the Westphalian Bight , but are classified as part of the Lower Rhine sand plates ( Niederrheinisches Tiefland ). It is believed that the Venn was formed around 4,500 years ago.
flora
In the almost 17 hectare high moor area that can be renatured ( habitat type 7120, see list of FFH habitat types ) of the Burlo-Vardingholter Venns, you will find Bult-Schlenken complexes and rich vegetation typical of high moorland with peat moss , woolly and marshmallow , sundew , cranberry and heather plants . Together with the transition and swinging lawn moors (LRT 7140) around the heather pond of the Entenschlatt, almost 21 hectares of the nature reserve are moors. In the duck lair, reed belts and willow growth indicate disturbances ( eutrophication ). Most of the region - nearly 45 ha - take breakage and swamp forests a predominantly birch - and Erlenbruchwald . In addition, moist heaths (4010) are of particular importance to a lesser extent . Wet meadows and grassland cover an area of around 20 hectares. The remainder is distributed primarily in deciduous , mixed and coniferous forests .
fauna

The Burlo-Vardingholter Venn is a retreat for a number of animal species that otherwise only occur sporadically or not at all in North Rhine-Westphalia. Honey buzzard , black woodpecker , wood sandpiper are species of particular interest to the Birds Directive . Redstart , green woodpecker , water rail , little grebe and goat milker are residents of the area who are also on the red list . Also, lesser spotted woodpecker , oriole and teal are native to the area. Among the many dragonflies , the great moss damsel, which is critically endangered and has one of its last occurrences in the state of North Rhine-Westphalia, should be emphasized. The moor frog, which is also endangered, is often to be found and the endangered smooth snake has also been identified. The sighting of the adder is documented from 1975 .
Measures for rewetting and development of the area
Large areas of the peat bog used to be crossed centrally by a deep drainage ditch. After this had been piped and sealed, large areas of the birch quarry forest died in its vicinity as a result of waterlogging . Then in 1983 earth walls were erected over a length of more than 2600 m in the south of the area for rewetting, and sheeting was drawn in down to the impermeable ground moraine at a depth of six meters.

The landscape plan Borken-Nord from 2001 pursues u. a. the aim of restoring or maintaining the biotopes typical of raised bogs in the core zone and of safeguarding endangered biotopes, species and communities with special consideration of so-called habitats and species of community interest in accordance with the Habitats Directive. In the expansion zone, the focus is on measures to rewet and extensify the areas used for agriculture and forestry. The conditions for bogs and reeds are to be improved.
Near the Entenschlatt, two small bodies of water were created in 2009 with EU funding, as well as an observation pulpit and an information board. There are two more information boards on the south side of the Venn (access to the dam) and on the Dutch side at the entrance to Wooldse Veen.
Overall, the measures to secure and long-term preservation of the Venn are considered complete.
Maintenance measures have been carried out by the NABU district association Borken for years . Father, teacher and entomologist Sigbert Wagener from Bocholt, who died in 2004, made special contributions to the preservation and scientific research of the area .
