An ethnobotanical study of medicinal plants (MPs) used by the local community has been carried out from January 5, 2014, to February 15, 2015, in Gozamin Wereda of East Gojjam Zone, Ethiopia. Te purpose of this study was to identify and document the use and conservation of MPs, along with indigenous knowledge of Gozamin community. Data were collected using semistructured interview, feld observation, and focus group discussions. Te collected data were assessed quantitatively using fdelity level, Jaccard’s Coefcient of Similarity, paired comparisons, direct matrix, and preference rankings. In total 93 MPs distributed under 51 families and 87 genera were identifed and for each taxon a local name (Amharic) was documented. Asteraceae with 9 (9.68%) species and Solanaceae with 7 (7.53%) species were families represented by more species in the study area. Out of these MPs collected, 80 plant specieswereusedforthetreatmentofhumanailments,24specieswere used against livestock diseases, and 11 common plant species were listed in both cases. Te most frequently used plant parts were the leaves followed by the roots. Te major threats to MPs in the study area were agricultural expansion, overgrazing, fre wood collection, mining, and cutting down trees for construction and furniture. Terefore, there is a need for appropriate in situ and ex situ conservation measures. 1. Introduction ethnobotanically rich as there are diverse ethnic groups with diverse cultures.
