This study aims to determine the diversity of trees in the protected forest area of KPH-P Unit XII Ladongi. This research was conducted at KPH-P Unit XII Ladongi, East Kolaka Regency. The study used the nesting plot method in a protected forest area in Anggaloosi Village. Sampling is based on 4 (four) cardinal directions. Each cardinal direction represents 4 plots with a size of 20 x 20 meters, so the number of plots used is 16 plots. The results showed that the protected forest area of KPH-P Unit XII Ladongi in Anggaloosi Village, Ladongi District, East Kolaka Regency found 30 tree species, consisting of 21 families and 29 genera. The most species was eha (Castanopsis buruana Miq.), based on the family Euphorbiaceae and the most common genus found was Magnolia. The species diversity index (H') is 3.1 this indicates that the plant species diversity index in the study area is high, the margalef index (R1) is 7.04 which indicates the tree species richness is in the low category and based on the evenness index (E) close to 1, which is 0.88, this shows that almost all species have the same abundance value
