Why conservation science matters, and how to make it count?


The amphibian decline is a marked fact with more than 40 % of species listed as threatened worldwide. When looking at the proportion of threatened amphibian species for each biome, East Asia becomes a hotspots for both biodiversity and species at risk of extinction. East Asia is also characterised by having provided most of the rice for the planet until recent times, resulting in the large majority of wetlands now transformed into agricultural wetlands, and therefore placing species diversity and abundance in modified landscapes. These changes have resulted in some advantages as rice paddies provide a regulated depth and hydroperiod, with a periodic drought limiting the presence of predators, and even resulting in range extension through land reclamation for salt tolerant species. The threats resulting from the landscape changes are however numerous and are linked to monoculture, the presence of concrete in the landscape and the resulting avoidance of specific areas and trapping in ditches, chemicals application, increased competition, higher risk of hybridisation and the absence of habitat for diurnal rest and wintering, among others. Additional risks related to human activities also include climate change. Because of the strong impact of human activities, less developed regions are strongholds for amphibian diversity and unexpected amphibian conservation champions should be praised, but in addition science based mitigation measures and policy recommendation are required.
