Tenter Bach und Bökerbach, Nature reserve in Remscheid, Germany.

Tenter Bach und Bökerbach is a 30.55-hectare nature reserve southeast of Remscheid's centre, registered as RS-001. Two streams, the Tenter Bach and the Bökerbach, cut notch-shaped valleys whose floodplains are often under water; the Tenter Bach meanders with flat and steep banks, breaks and gravel bars. Birch, oak and beech woods cover the slopes, with dry pastures on the northern heights.

The area has been protected since 15 November 2001, when it was designated under the number RS-001 with a size of 30.55 hectares. With the Remscheid-West landscape plan taking legal effect, it replaced the former Bökerhöhe nature reserve of about 7 hectares.

The reserve is a habitat complex of wet meadows, dry grassland, a heath remnant and wet woodland, protected for species such as the kingfisher, green woodpecker, grass snake, river limpet, marsh violet and thyme-leaved speedwell. The Tenter Bach keeps a winding, meandering course with flat and steep banks, small breaks and gravel bars.

The reserve lies southeast of Remscheid's core, with the A1 along its eastern edge and the B229 to the north. The terrain is a deeply cut valley with steep slopes, partly flooded floodplains and no marked visitor infrastructure in the sources. Access is via the surrounding road network; the neighbouring Westerholt reserve (44.7 ha) lies to the northeast.

The streams form natural meandering courses with varied banks, gravel bars, and diverse plant communities that stand out from engineered waterways. This natural stream pattern is uncommon in an industrialized urban region.
