Native orchids are excellent indicator species for natural, species-rich habitats. These habitats need protection and preservation amidst a global biodiversity crisis.
Native orchids have adapted to a variety of habitats. One thing all these habitats have in common, is that they are poor in nutrients and orchids are able to get by on very little. This is due to their close association with root fungi, on which they depend even during germination. In their underground storage organs, orchids can build up reserves that allow them to flower quickly at a favorable time.
In the area of the former open-cast ore mines, secondary calcareous grasslands rich in species have developed on the Dogger and Minette strata in the course of the last fifty years.
The semi-arid grasslands of the Stone Marl Keuper have formed mainly on the slopes and hilltops of the Keuper landscape. They are home to the most species-rich orchid sites.
Semi-dry grasslands on shell limestone are found on the southeastern border of the Oesling and in the Moselle valley. In the Oesling, silicate grasslands have developed on the south-facing slopes of the Devonian shales.
