Conservation management of rare and predominantly selfing tropical trees: an example using Hopea bilitonensis (Dipterocarpaceae)
Hopea bilitonensis is an extremely rare and predominantly selfing dipterocarp in Peninsular Malaysia. A comprehensive research was initiated to assess the ecological genetics of H. bilitonensis to elucidate specific ecological and genetic requirements and subsequently to recommend conservation strategies. The objective for conservation of a rare plant such as H. bilitonensis differs from that of a common plant. For common plants, the conservation strategies are to prevent the species from becoming endangered. In contrast, for rare plants, the final race against extinction is being fought. Tropical forests are rich in plant species diversity and obtaining adequate knowledge to set conservation strategies for the majority of these species might be difficult. Thus, it is suggested that for the conservation of tree species, the species can be grouped according to their life history traits. The information generated for a species can then be adapted to species that have similar types of life history traits. We have recently generated the ecological genetics information for a rare and predominantly outcrossed dipterocarp (Shorea lumutensis). This study on H. bilitonensis will provide ecological genetics information for the conservation of rare and predominantly selfing dipterocarps.
