Conservation of some rare and endangered plants from Peninsular Malaysia

Summary: Malaysia has approximately 15,000 species of vascular plants. Its flora is distributed between two major geographical regions; Peninsular Malaysia on mainland Asia and the states of Sabah and Sarawak on the island of Borneo. Peninsular Malaysia has over 8,300 plant species and Sabah and Sarawak in a recent estimate have about 12,000 species. Total species endemism for Peninsular Malaysia is about 30%; its tree endemism is 26.3%. For Sabah and Sarawak, the endemism level is higher, recently revised figures gave a tree species endemism of 42.1%. Malaysia has recently published its national strategy for plant conservation, which now forms the basis of conservation activities for the country. Since 2004, we have been running a project entitled "Conservation Monitoring of Rare and Threatened Plants of Peninsular Malaysia", in which conservation status assessment is scored for a number of families. Results of the assessment of 458 taxa included 46.1% in some threat category. Detailed conservation studies are in progress for 33 species of threatened plants. Initial work on these species include spatial distribution studies at regional level based on herbarium records, and at a more local level, population studies to determine demography of populations. Regular phenological observations were also made for many of the species. © 2011 The Board of Trustees of the Royal Botanic Gardens, Kew.
