Abstract: Endangered species protection and wild rehabilitation is a major issue facing mankind, which requires more scientific and theoretical guidance and application practice from a multidisciplinary perspective and multi-type technology platform, so as to better serve the biodiversity protection, product output and sustainable development of local characteristic ecosystems. Focusing on coastal endangered wild tree species in Zhejiang Province, China, this paper summarizes the past research and achievements on endangered tree species, the existing problems and shortcomings, with an overarching aim to provide research programs for the protection and restoration of endangered tree species on islands in the future. We proposed that future research objectives would be the construction of near-natural habitats and the construction of wild return populations. Combining theories and technologies related to global change ecology, dendrochronology, microbial ecology, population ge-netics, bioconservation engineering and other disciplines, from the perspective of multi-scale genes, cells, individuals, commu-nities, and ecosystems, we would like to develop a series of integrated technologies and equipment, such as historical original habitat and near-natural habitat reconstruction, molecular breeding, microbial rejuvenation, extreme climate early warning and artificial intelligence monitoring, application demonstration base construction. The expected results can provide risk early warning for the coastal endangered tree species and their typical ecosystems to cope with extreme climate and provide common technologies and demonstration cases for biodiversity protection.

Key words: climate change, endangered tree species, near-natural habitat construction, wild population reintroduction, biodiversity conservation
