Nature protection and preservation in Indonesia is carried out by designating certain places as nature reserves. One area that has been chosen as a nature reserve in East Java is the Mount Sigogor Nature Reserve, with the most extensive type of mountain tropical rainforest in the area. The purpose of this study was to determine the composition of species at the level of trees and species dominant in mountain tropical rainforests. Data collection method uses the quadrant method (Point Center Quarter Method). Relationship analysis uses the 2 × 2 Contingency Table method. Based on the results of the study, it founded that the vegetation of Mount Sigogor Nature Reserve consisted of at least 47 tree species including 23 families dominated by couples ( Quercus sondaica BL Miq) with INP of 37.93%. The next sequence was Dodonea viscosa with INP of 35.90% followed by Casuarina sp with INP of 28.21%, Litsea glutinosa and Persea odoratissima (Nees) Kosterm with INP of 27.11% and 16.29% respectively. The pair of species that tend to live together is Quercus sondaica with Litsea glutinosa.
