Monitoring of Danish Orchids

Survey of orchids | The background for the Monitoring of Danish Orchids

The monitoring of Danish orchid populations and their habitats was initiated in 1943 when the Buderupholm State Forest District commenced counting the local population of Lady's slipper (Cypripedium calceolus). The monitoring of more orchid species started in 1982. Since then all 45 native Danish orchids have been monitored for a longer or shorter period e.g. confined by habitat deterioration or population extinction.

The widely distributed species are monitored on selected sites, only, while species known on 10 sites or less are monitored on all or nearly all localities.

All Danish orchids are legally protected. Thus, it is forbidden to damage or collect specimens and their seeds. On the other hand everyone is free to study the orchids in the wild. Some orchids have strict demands to their habitat, as they are involved in a complicated symbiosis with fungi. Other species may inhibit various habitats and thus be distributed in most parts of Denmark.

When you activate an international name in the Survey of orchids a list will appear. The list contains the Danish names on the sites where the orchids are monitored. When a name is activated a histogram showing the annual census appears.


Orchids in the Red Data Book

Twenty-one of forty-six orchid taxa i.e. 45% are included on the Red Data Book. This implies that the taxa are either regionally extinct (three orchids), critically endangered (three orchids), endangered (eight orchids) or vulnerable (seven orchids). More information on the homepage of The Danish Red Data Book.
