The species of this family are of major importance in the timber trade in the State. However, about 75% of Sarawak dipterocarps are listed in the IUCN Red List of Threatened Species which could have negative implication for the timber business. Due to the concern from the timber industry, a study is carried out to re-assess the conservation status of the three genera of dipterocarps (i.e. Dipterocarpus, Dryobalanops and Shorea) in Sarawak as they are the major commercial timbers. This paper highlights the findings from this study where 169 species from the three genera were assessed. In the IUCN Red List of Threatened Species 2013, 95% of the species from the three genera are listed as threatened. However, this study provides a more accurate assessment with only 42% of the species under the threatened category. At the same time conservation measures are emphasized particularly for those species that are endemic to Sarawak.

This study was conducted to determine the diversity and species composition of trees in Mina Wildlife Corridor. Mina Wildlife Corridor is part of the Planted Forest Zone in Bintulu. Fourteen (14) of 0.25 hectare sample plots were established to determine the diversity of trees. A total number of 2515 individual trees comprising 618 species from 58 families and 171 genera were recorded. Dipterocarpaceae, Euphorbiaceae, Myristicaceae, Burseraceae and Myrtaceae are the dominant families revealed from the study area. There were 718 individual trees per hectare with Macaranga hypoleuca having the highest density at 14 individuals per hectare. Further assessment should be conducted at other localities in Mina Wildlife Corridor to obtain more information and technical data of the wildlife corridor. The significance of findings will be discussed in the paper.
