During data collection,5 transects of 20 m width and<span style="mso-spacerun: yes;">  </span>1 km length of each in Wanariset Semboja forest complex and 10 transects in Pusrehut UNMUL and Protection Forest areas were established. The study shows that species richness of trees in those three forest complexes are relatively similar, however, the regeneration stage in Pusrehut UNMUL forest complex is relatively higher than those in another two areas.<span style="mso-spacerun: yes;">  </span>Medang (Litsea firma),<span style="mso-spacerun: yes;">  </span>Acacia (Acacia <span style="mso-bidi-font-style: italic;">sp</span>.), and Mahang (<span style="mso-bidi-font-style: italic;">Macaranga gigantea</span>) are dominant tree species in Wanariset Semboja, Pusrehut UNMUL and Protection Forest areas, respectively.<span style="mso-spacerun: yes;">  </span>Mahang (<span style="mso-bidi-font-style: italic;">M. gigantea</span>) as pioneer species is also commonly dominated forest regeneration in Taman Hutan Raya Bukit Soeharto.<span style="mso-spacerun: yes;">   </span>Based on tree’s<span style="mso-spacerun: yes;">  </span>diameter distribution, those forests show balanced uneven-aged forests in which the large amount of trees are concentrated in the height class of 10 to 29 m.<span style="mso-spacerun: yes;">  </span>Species diversity of those forests are relatively high (H > 2.5) either for seedling, sapling, pole or tree growth stages, however, those forests show different plant communities (IS < 70 %).</span></span></em></p><p class="JUDUL" style="margin: 0cm; margin-bottom: .0001pt; text-align:
