Why Sallandse Heuvelrug National Park stands out
Sallandse Heuvelrug is best known for its extensive heathlands and its status as the final stronghold of the black grouse in the Netherlands. The park preserves one of the country's most important remaining populations of this species, which has disappeared from virtually all other Dutch heathland areas. The heathlands, which developed historically through centuries of sheep and goat grazing combined with soil removal for fertilizer, create a distinctive purple-flowering landscape in late summer. The park also contains the Holten Canadian War Cemetery, one of the largest military cemeteries in the Netherlands with 1,393 graves of Canadian soldiers from World War II, adding historical significance to the natural landscape.
Sallandse Heuvelrug National Park history and protected-area timeline
The history of Sallandse Heuvelrug reflects the broader transformation of Dutch heathlands from productive cultural landscapes to nature reserves. The geological history dates to approximately 150,000 years ago during the Saalien glaciation, when ice sheets advanced across what is now the Netherlands and pushed up river deposits into the high ridges that form the current landscape. Following the last glaciation, forests developed naturally across the area, but human activity from the Middle Ages onwards dramatically altered this. Population growth led to widespread forest clearance, and the combination of grazing pressure and soil removal for agricultural purposes transformed forested areas into heathland. This process continued for centuries, creating the extensive heather-covered landscapes that now characterize the park. In the early twentieth century, as the ecological degradation of the heathlands became apparent and the Dutch government sought to address erosion while producing timber, extensive pine forests were planted across the area. The formal designation of the national park in 2004 marked a new chapter in the area's management, prioritizing ecological restoration and nature conservation over timber production. The park also contains significant historical heritage related to World War II, including the Holten Canadian War Cemetery and the site of the Twilhaar labour camp, where Jewish forced labourers were held before transport to Westerbork and subsequently to Auschwitz.
Sallandse Heuvelrug National Park landscape and geographic character
The landscape of Sallandse Heuvelrug National Park is defined by a series of elongated glacial ridges running roughly north to south between Hellendoorn and Holten. These ridges, known as stuwwallen, were created when ice sheets during the Saalien glaciation pushed up pre-existing river deposits of sand, gravel, and clay into large mounds that now form the distinctive hills of the area. The highest point, the Grote Koningsbelt, reaches 75 metres above sea level, providing panoramic views across the surrounding Dutch lowlands. Between and around the ridges lie dry valleys, created during the Weichselien glaciation when permafrost conditions and meltwater erosion carved channels that now stand as landscape features even though they no longer carry surface water. The present-day landscape reflects centuries of human modification: areas of open heathland alternate with coniferous plantations established in the late nineteenth and early twentieth centuries. More recently, active management has involved removing some pine forest to restore open heathland habitat, particularly in areas important for black grouse conservation. The heathlands are characterized by their purple heather blooms in late summer and the presence of scattered birch and oak that have established in some areas, creating a mosaic of open and wooded habitat.
Sallandse Heuvelrug National Park ecosystems, habitats, and plant life
The nature of Sallandse Heuvelrug is characterized by extensive heathland habitats that have become increasingly rare across the Netherlands. The heathlands support a distinctive flora adapted to acidic, nutrient-poor sandy soils, with lingonberry and cranberry among the characteristic plant species found in the area. The pine forests, while originally planted for timber production, have developed into important woodland habitats supporting different species assemblages. Some areas have seen the natural establishment of deciduous trees including birch, oak, and beech, creating diverse woodland structure. The park is designated as part of the Natura 2000 network, reflecting its European-level importance for conservation. However, the park faces significant ecological challenges, including hydrological issues with the area being too dry, small and fragmented habitats, recreational disturbance pressure, and nitrogen deposition that has made soils overly acidic and nutrient-rich. These factors have led to concerns about the ecological quality of the site and the ability to achieve conservation objectives for key species.
Sallandse Heuvelrug National Park wildlife and species highlights
Sallandse Heuvelrug is notable for its wildlife, particularly the presence of species that have become rare or extinct elsewhere in the Netherlands. The park holds the last remaining population of black grouse in the country, a species that represents a conservation priority and for which specific management measures have been implemented, including the closure of areas during the breeding season and the expansion of open heathland at the expense of forest. The European nightjar is another notable bird species present in the area. The reptile community includes the viviparous lizard and sand lizard, while damp areas support amphibians including the brown frog, great crested newt, and smooth newt. Among mammals, roe deer, fox, and badger are present, along with mustelids including stone marten, polecat, weasel, and ermine. In 2018, a radio-collared wolf briefly passed through the area, representing a rare visitation from a species that is recolonising parts of the Netherlands. Nearly eighty bird species breed in the area, including whinchat and raven. The open heathlands also support the relatively common slowworm.
Sallandse Heuvelrug National Park conservation status and protection priorities
The conservation significance of Sallandse Heuvelrug derives primarily from its role as the last refuge for the black grouse in the Netherlands, a species that has been lost from virtually all other Dutch heathland areas. The park is designated as a Natura 2000 site, recognizing its importance at the European level for heathland ecosystems and the species they support. However, the conservation status of the area has given rise to significant concern. A 2023 assessment by the Provincial Ecological Authority identified multiple threats to the park's ecological quality: the area is regularly too dry due to hydrological issues, existing habitats are too small and too fragmented, recreational disturbance is excessive, and nitrogen deposition has degraded soil conditions to the point where they are too acidic and nutrient-rich for optimal heathland function. The assessment recommended urgent action on hydrology and nitrogen deposition to prevent further deterioration and to give hope of achieving Natura 2000 conservation targets. Management measures include grazing by Scottish Highland cattle to maintain open heathland, night-time road closures to reduce disturbance to breeding black grouse, and programmes to combat the natural succession of heathland to grass and woodland.
Sallandse Heuvelrug National Park cultural meaning and human context
Sallandse Heuvelrug contains significant cultural and historical heritage beyond its ecological value. The Holten Canadian War Cemetery, located on the Holterberg, is one of the largest military cemeteries in the Netherlands, containing 1,393 graves of Canadian soldiers who died during the final stages of World War II. The cemetery is maintained by the Commonwealth War Graves Commission and remains accessible to the public. On the Nijverdalsche Berg, the Twilhaar area contains the remains of historical settlement and a traditional sheep pen, along with a memorial to the labour camp of the same name. In 1942, Jewish forced labourers were transported from this camp to Westerbork and subsequently almost all were murdered at Auschwitz. The landscape also bears traces of more recent military history, including a reconstructed V1 launch ramp near Nijverdal. The area has a long tradition of agricultural use through sheep and goat grazing, which created and maintained the heathland habitats that now define the park's character.

Best time to visit Sallandse Heuvelrug National Park
The best time to visit Sallandse Heuvelrug depends on what visitors hope to experience. Late summer, particularly August and early September, offers the peak flowering of the heather, when the heathlands display their characteristic purple coloration. This is also when the black grouse are most visible during their late-summer display period. Spring brings bird activity and the emergence of heathland flowers, while autumn can offer atmospheric conditions across the open moorland. Winter visits provide the opportunity to experience the landscape in its starkest form, though the park's facilities may have reduced hours. For those interested in wildlife, the breeding season (spring and early summer) offers the best opportunities to see birdlife, though some areas are closed during this period to minimize disturbance to sensitive species.
