État de la populationExpert
The population of Angraecum pauciramosum is currently thought to be decreasing since its habitat is threatened by forest degradation due to slash-and-burn agricultural practices (tavy), mining activities, illegal logging, and timber harvesting for small-scale subsistence use. The number of individuals of A. pauciramosum is not known and cannot be estimated since the species is an epiphyte on the trunk or branches of trees in both humid and subhumid forests, and mossy shrubland. The species is reported to be a rather common species (Bosser and Lecoufle 2011).

Description complète des menacesExpert
This species experiences a continuing decline in EOO, AOO, habitat quality, number of locations, and number of mature individuals because of habitat destruction due to shifting cultivation and mining. Twenty subpopulations of this species have been recorded on the footprint of a mining project undergoing intense human pressure such as forest clearing. Ten subpopulations are known from unprotected forests subjected to forest exploitation, slash-and-burn agricultural practice (tavy), selective logging, timber harvesting for small-scale subsistence, and wildfires.

Mesures de conservation recommandéesExpert
Nineteen occurrences of the species are situated within seven protected areas: the Analamazaotra National Park (nine occurrences), the Andringitra National Park (one occurrence), the Mantadia National Park (three occurrences), the Makira Natural Park (one occurrence), the Protected Harmonious Landscape of the Anjozorobe-Angavo Complex (one occurrence), the Natural Resources Reserve of the Marojejy-Anjanaharibe South-Tsaratanàna Corridor - Northern Part (one occurrence), the Torotorofotsy protected area (two occurrences) and the Ranomafana National Park (one occurrence). The species is also currently placed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). It has been also brought to cultivation at Ambatovy and Antananarivo shade houses. Ex situ conservation is recommended (micro-propagation, and living collections). It should be included in the list of Malagasy protected species. Further awareness building is recommended for local communities and national authorities.
