État de la populationTexte officiel évaluation IUCNExpert

The population of Angraecum caricifolium is currently thought to be decreasing since its habitat is threatened by forest degradation due to slash-and-burn agricultural practices (tavy), forest clearing due to mining activities, and selective logging, timber harvesting for small-scale subsistence use. The number of individuals of A. caricifolium is not known and cannot be estimated since the species is an epiphyte on the trunk or branches of trees in a humid, subhumid forest, and mossy shrubland.

Description complète des menacesTexte détaillé évaluation IUCNExpert

Eight occurrences of Angraecum caricifolium are located outside protected areas and are threatened by forest clearing for agriculture, cattle using the forest for pastures, wildfires, and illegal logging. In addition, eight occurrences have been made in the Ambatovy footprint of a mining project undergoing intense human pressure such as forest clearing. These former occurrences must be considered as extirpated. The loss of the occurrences in the footprint of mining has and will continue to induce a continuing decline in the AOO, the number of subpopulations, and the number of mature individuals.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

Three occurrences of the species are situated within three protected areas: Montagne d'Ambre National Park, Analamazaotra Special Reserve, and Andringitra National Park. The species is also currently placed in Appendix II of CITES. Ex situ conservation is recommended (micro-propagation, seed banking, and living collections). Angaraecum caricifolium should be included in the list of Malagasy protected species. Further awareness building is recommended for local communities and national authorities.
