Epipactis tallosii is very rare and local with small and isolated populations over a scattered distribution. The trend of the population is decreasing and the area of occupancy of the species is below 500 km². The species is threatened by the destruction of forests, clearing of old trees, inappropriate woodland management, construction of forests roads, drainage, urbanisation, tourism, and consumption by animals. Therefore, Epipactis tallosii is assessed as Endangered.

Threats [top]

Major Threat(s):

Epipactis tallosii is threatened by habitat loss caused by the destruction of forests, clearing of old trees, inappropriate woodland management, construction of forest roads, and drainage of high ground water. In addition, it is harmed by urbanisation,  tourism, recreational activities, and digging and consumption by animals (Delforge 1995, GIROS 2009).

Conservation Actions [top]

Conservation Actions: All orchids are included under Annex B of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). This orchid is listed as Critically Endangered in Czech Republic (Holub and Procházka 2000) and Near Threatened in Hungary (Király 2007).

The following actions are recommended to protect Epipactis tallosii;

  • Protection of the woodland habitat from destruction, clearance and unsuitable management.
  • Fencing vulnerable sites to protect the species from wild animals.
  • Appropriate woodland management to control the amount of sunlight reaching the forest floor
  • Sympathetic management of isolated populations.
  • Avoid drainage of the habitat.
  • Raise public awareness.
  • Protection through legislation which bans collection of the species.
  • Ex situ conservation: artificial propagation, re-introduction, seed collections.
  • Monitoring and surveillance of existing populations and sites.
  • Estimate the population size and study their dynamics.
