Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. The platypus offers a useful lesson in conservation: before acting, it helps to know where the animal still lives, and where risks are growing. Australia’s best-known oddity is also difficult to count, reports contributor Paul Harvey for Mongabay. It feeds around dawn and dusk, spends much of its life underwater in rivers, and leaves few obvious signs. That makes its decline harder to measure and harder to manage. The IUCN Red List classifies the species as near threatened, based on an estimate of about 50,000 animals, though researchers say the true number is uncertain. That uncertainty has become more important as pressure on rivers increases. Drought can shrink the pools where platypuses feed. Bushfires can damage riverbanks and nearby vegetation. Floods can inundate burrows before animals can escape. Pollution from wastewater, mining, industry, and urban runoff can reduce the aquatic invertebrates that make up much of their diet. There is room for optimism because scientists have now developed a framework for deciding when to help platypuses where they are and when animals may need to be moved. Zoos are also preparing for a clearer role in emergencies, including temporary care for animals stranded by drought, fire, or flood. Citizen science can help close the information gap. Projects that map sightings show where platypuses are still being seen. Environmental DNA, collected from water samples, can detect their presence without needing to trap or even…This article was originally published on Mongabay
