Gymnadenia widderi is very local and extremely rare where it occurs, known from a few sites in three fragmented areas in Europe: Styria in Austria, Bavaria in Germany and Abruzzo in Italy. The area of occupancy is below 500 km² and the subpopulations as well as their habitats are declining due to recreational activities, tourism, and inappropriate grazing management. Therefore, Gymnadenia widderi is assessed as Endangered.
Gymnadenia widderi is a European endemic, currently known from a few sites in Styria in Austria, Bavaria in Germany and Abruzzo in Italy. The species can be found from 1,500 to 2,200 m altitude. (Delforge 1995, GIROS 2009, Rossi 2002, The Board of Trustees of the Royal Botanic Gardens, Kew 2010).

Gymnadenia widderi is very local and extremely rare, known from a few sites in three areas and forming groups with low density. The population size is unknown and the population is decreasing due to numerous threats. (Delforge 1995, GIROS 2009, Rossi 2002). In Bavaria, it is found in only two sites in the Alps (Ahlmer 2010).
|Current Population Trend:||Decreasing|
|Habitat and Ecology:|
Gymnadenia widderi can be found in short, calcareous alpine grassland. This species grows in full sunlight and flowers from June to August. (Delforge 1995, GIROS 2009, Rossi 2002).
|Use and Trade:||
There are no known uses.
Gymnadenia widderi is potentially threatened by recreational activities and tourism. Like all grassland orchids this species requires a specific level of grazing; too little and the species suffers from invasion of more competitive plants; too much and the diversity of the species is lost. (Delforge 1995, GIROS 2009, Rossi 2002).
All orchid species are included under Annex B of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). This plant is listed as Endangered in the regional red list of Bavaria (Ahlmer 2010). The following actions are recommended to protect Gymnadenia widderi:
