STF1053 OVERVIEW OF VALUES OF BIODIVERSITY, CURRENT THREATS, EFFORTS TO SUSTAIN BIODIVERSITY VALUES OF BIODIVERSITY Biodiversity supports different types of ecosystem services: Provisioning – products obtained from ecosystem services Regulating – benefits obtained from regulating services Cultural – non-material benefits Supporting – services necessary for the production of all other ecosystem services IN SITU CONSERVATION The conservation of ecosystems and natural habitats and the maintenance and recovery DEFINITION OF of viable populations of species in their IN SITU natural surroundings. CONSERVATION In situ conservation therefore covers not only species and ecosystems but also genetic variability. Conservation and maintenance of THE CONCEPT selected/target individual species in their natural habitats/ecosystems through OF IN SITU conservation or management plans. CONSERVATION Restoration, recovery or rehabilitation of habitats. EX SITU CONSERVATION ) EX SITU CONSERVATION STRATEGIES Ex situ conservation: conservation of biological diversity components (seed, clone, live saplings, pollen, or their DNA) outside their natural habitat. Ex-situ conservation makes it easier for scientists to access, study, distribute and use plant resources. EX SITU CONSERVATION STRATEGIES EXAMPLES OF EX-SITU CONSERVATION IN MALAYSIA ARBORETA & FIELD GENEBANKS (as living collections) - medicinal plants, fruit trees, timber species, ornamental plants SEED GENEBANKS - rice vegetables CAPTIVE BREEDING CENTRES - Sumatran rhinoceros seladang sambar deer REHABILITATION CENTRES - orang-utan TURTLE SANCTUARIES - marine turtle TURTLE HATCHERIES - river terrapin marine turtle CHALLENGES TO PLANT CONSERVATION Law and Regulations National Policy on Biological Diversity 2022-2030
