Cedrela was one of the economically most important timber in the past, due to its wood properties. The genus has a long history of overharvesting and selective logging; as a consequence a substantial genetic degradation have occurred in Ecuador. Currently, three species of Cedrela are included in the IUCN Red List. C. odorata and C. nebulosa are listed as vulnerable species and C. fissilis as endangered species. In spite of their conservation status and priority, few studies related to geographical distribution have been done. Then, the geographic distribution at local level had been carried out to provide a valuable tool to the conservation and management of these species. Field sampling and herbarium compilation showed C. montana is restricted to the Ecuadorian highlands in the western and eastern Andean montane region between 805 to 3200 masl (meters above sea level). Cedrela nebulosa is located in Andean region about 1400 to 2300 masl. C. odorata is the most widely distributed, occupying areas in the Amazon (200-1300 masl), Pacific (330-825 masl) and insular regions (350 masl). While, Cedrela fissilis is only found in the Amazon Region about 200 to 510 masl. This basic information about current distribution and abundance of cedar species is primordial to generate sufficient tools to formulate the strategies of management and conservation of these species in the country. The widespread distribution of C. odorata have been found in the Amazonian and Pacific regions, indicating that it is adapted to tropical rainforest and tropical monsoon climates. To prove if there are adaptations to both habitats morphological, ecological and phylogenetic studies must be carried out.Cedrelaendangered speciesecoregionaltitude[Baccini, A., Goetz, S.J., Walker, W.S., Laporte, N.T., Sun, M., Sulla-Menashe, D., Hackler, J., Beck, P.S.A., Dubayah, R., Friedl, M.A., Samanta, S. and Houghton, R.A. 2012.
