The Bruchhauser Steine area is a European bird sanctuary (protected area identification DE-4617-401) in the German state of North Rhine-Westphalia that was designated by the Arnsberg Regional Council in 2008 .
The Birds Directive of the European Union serves to preserve the wild bird species native to the territory of its member states and to regulate the protection, management and regulation of these birds, their eggs and habitats .
location
The approximately 85 hectare “Bruchhauser Steine” bird sanctuary is located in the area of the city of Olsberg in the Rothaar Mountains . Its two sub-areas extend on the northwest slope of the 728 m high Istenberg , north and south of the state road 743, between the districts of Bruchhausen in the west and Elleringhausen in the north.
It is named after the four rocks " Bornstein " (92 meters high / 700 m above sea level ; preferred breeding site for peregrine falcons ), " Feldstein " (45/756), " Goldstein " (60/712; breeding site for eagle owls ) and " Ravenstein " (72/701).
They consist of porphyry and the basement of soft clay slate , which was formed around 370 million years ago in the Devonian period from deposits of a prehistoric sea. During later volcanism 290 million years ago, lava penetrated into crevices of this clay slate to the sea floor. When the lava cooled down, various lava rocks such as diabase and quartz keratophyres were formed . During the Variscan Folding , around 100 million years later at the end of the Carboniferous Age, the former sea floor was turned into a mountain range . In the following millions of years this mountain range was eroded away again. During erosion, the harder lava rocks resisted weathering better than the clay slate surrounding them. So the rocks of the Bruchhauser stones remained, while the clay slate surrounding them disappeared.
description
The “Bruchhauser Steine” protected area is described as the area of a “structured mixed montane beech forest with breeding occurrences of peregrine falcon and eagle owl as well as unique rock vegetation (ice age relics), especially mosses and lichens , which is extremely rare in North Rhine-Westphalia .
Habitat classes
| N06 - inland waters, standing and flowing | 1 % | |||
| N08 - heather, scrub, macchia, garrigue, phrygana | 2% | |||
| N10 - Moist and mesophilic grassland | 29% | |||
| N16 - deciduous forest | 50% | |||
| N20 - artificial forests | 11% | |||
| N22 - inland rocks, scree and rubble heaps, sandy areas | 7% | |||
Habitat types
The following habitat types occur in the protected area :
- 9110 - Hainsimsen-Buchenwald
- 9180 - Gorge and slope mixed forests "Tilio-Acerion"
- 91E0 - floodplain forests with black alder and common ash
Protection purpose
The general protection purpose is the urgent preservation of the peregrine falcon breeding site as well as the lichen and moss-rich rock vegetation through near-natural forest management, a climbing ban, recreational management and extensive grassland grazing.
The area-related conservation and development goals are described differently depending on the species .
Breeding birds
Gray woodpecker

Preservation and development of extensive, habitat-typical deciduous and mixed forests - especially beech forests - with up to ten trees per hectare and high proportions of old and dead wood , avoiding the fragmentation and islanding of the populated forest areas, the preservation and development of sunny clearings, forest edges, light forest structures and small structures as well as grassland as food areas, the improvement of the food supply (e.g. reduced fertilization, no pesticides), the maintenance of cave trees and the promotion of a permanent supply of suitable breeding trees (especially> 100-year-old beeches, trees with damaged areas) and avoidance of disturbances in the breeding grounds from March to July
Little Owl
Preservation and development of extensive, richly structured mixed forests - especially beech forests - with high proportions of old and dead wood and with daily cover (small spruce stands), avoiding the fragmentation of the populated forest areas, preserving and developing clearings as food areas, preservation and promotion a permanent supply of cave trees (black woodpecker caves; if necessary, temporary installation of nesting boxes; check for possible breeding occurrences before trees are felled in occurrence areas) as well as avoiding disturbances at the breeding sites from March to July
Black woodpecker
Preservation and development of deciduous and mixed forests typical of habitats - especially beech forests - with high proportions of old and dead wood, avoidance of fragmentation of populated forest areas, preservation and development of sunny clearings, forest edges, light forest structures and small structures (stumps, dead wood) as food areas , the improvement of the food supply (no pesticides), the maintenance of cave trees and the promotion of a permanent supply of suitable breeding trees (especially> 100-year-old beeches) and the avoidance of disturbances in the breeding grounds from March to June
The black woodpecker ( Dryocopus martius ) was bird of the year in Germany in 1981 .
Eagle owl
Preservation of undisturbed rocks, ledges and rocky crests, renouncing backfilling and / or afforestation of abandoned quarries, avoiding the fragmentation of populated habitats, possibly careful clearing of growing breeding sites, avoiding disturbances at the breeding sites (February to August) and the defusing or protection of dangerous electricity pylons and overhead lines
The eagle owl ( Bubo bubo ) was bird of the year in Germany in 2005.
Peregrine falcon
Preservation of open rock walls, ledges and rocky knolls with niches and overhangs, if necessary the careful clearing of overgrown breeding sites, the preservation of the breeding sites on buildings and the avoidance of disturbances in the breeding sites from March to June
The peregrine falcon ( Falco peregrinus ) was bird of the year in Germany in 1971.
