État de la populationTexte officiel évaluation IUCNExpert

Cephalanthera longifolia is widespread and often abundant. The trend of the population remains unknown but many sites have been declining (Lang 2004, Delforge 1995).

Description complète des menacesTexte détaillé évaluation IUCNExpert

Cephalanthera longifolia is threatened due to changes in woodland management; the neglect of woods leading to the disappearance of glades, the thickening of tree cover and the development of coarse woody habitat. Many populations have been lost through inappropriate woodland management which can cause the plants to dry up as a result of too much light, forest fires, deforestation for building and construction work purposes as well as plant collection (Lang 2004, Harrap and Harrap 2009, Delforge 1995).

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

All orchid species are included under Annex B of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Cephalanthera longifolia can be protected by:

Protection of the species natural habitats by a reduction in canopy to let more light in and keeping the glades relatively small as the species requires a degree of shade.
Control/removal of the ground vegetation to minimise competition between Cephalanthera longifolia and other species. This can be managed by strimming after the summer.
Light grazing (preferably with cattle) over the winter can be useful to create areas of bare ground for germination.
Management for bees is necessary to guarantee that as many flowers as possible are pollinated. Chances of pollination can be maximised by ensuring that flowering species that produce suitable sources of food for the bees and produce pollen at the same time as C. longifolia are present close to the orchid.
Protection of the living individuals through legislation that bans the species from being picked or dug up.
Ex situ conservation: Artificial propagation, re-introduction, seed collections.
Monitoring the existing populations and sites.
Estimate the population size and study their dynamics (Lang 2004, Delforge 1995, Plantlife International 2006).

In the UK, a number of countryside conservation schemes provide assistance to land managers conserving sites of Cephalanthera longifolia. The most appropriate are:

Environmental Stewardship: This is a new agri-environment scheme, which provides funding to farmers and other land managers in England who deliver effective environmental management on their land.
Protected Road Verges: Many district councils run protected road verge schemes (Plantlife International 2010).
