Background and methods – Cedrelopsis (Rutaceae), commonly known as Katrafay, is an endemic genus of Madagascar and consists of eight species of trees and shrubs growing on different substrates and in primary and/or modified ecosystems. These species of Cedrelopsis are plant parts most used plants for several purposes. Thus, an ecological assessment was undertaken in aim to understand the pressures and threats to populations, define their conservation status, and establish a strategy for sustainable management.
Key results – Approximately 65 to 100% of subpopulations of Cedrelopsis are in sites with no appropriate conservation measure. Timber and habitat loss are the major threats. Cedrelopsis procera is critically endangered, while C. gracilis, C. longibracteata, C. ambanjensis, and C. rakotozafyi are in danger of extinction; C. trivalvis, C. grevei, and C. microfoliolata are vulnerable.
Discussion and conclusion – Human activities including wood use and burning are the main pressures contributing to the depletion of species. As regards their conservation status, Cedrelopsis species are actually in an intermediate level between the categories “vulnerable” (VU) and “critically endangered” (CR). Managing their populations and habitats requires effective participation of key players. Key words – Cedrelopsis, Katrafay, Madagascar, Rutaceae, ecology, IUCN conservation status.
