How do you conserve some of South America’s most elusive mammals while working alongside ranchers, indigenous communities, beekeepers, and local governments? In this episode of The Think Wildlife Podcast, we are joined by Dr. Arnaud Desbiez, Founder and President of the Instituto de Conservação de Animais Silvestres (ICAS), to explore over two decades of pioneering wildlife conservation and biodiversity conservation in Brazil.
Dr. Desbiez introduces listeners to two extraordinary yet overlooked species—the giant armadillo and the giant anteater—whose ecological importance extends far beyond their rarity. As true ecosystem engineers, giant armadillos create extensive burrow systems that provide shelter for hundreds of other species, making them a keystone component of healthy tropical ecosystems. Giant anteaters, meanwhile, are among South America’s most distinctive tropical mammals, yet face increasing threats from habitat loss, wildlife vehicle collisions, wildfires, pesticides, and fragmentation.
The conversation begins with Dr. Desbiez’s journey from France to Brazil before diving into the remarkable Pantanal, the world’s largest freshwater wetland and one of the planet’s most spectacular wetland conservation landscapes. He explains why the Pantanal, Cerrado, Amazon rainforest, Atlantic Forest, and Chaco together support exceptional South American wildlife, while also facing mounting pressures from Amazon deforestation, climate change, altered rainfall, El Niño, devastating Pantanal fires, and expanding agricultural development.
We then explore decades of research on giant armadillo conservation and giant anteater conservation, including discoveries about their ecology, reproduction, habitat requirements, genetics, and behaviour. Dr. Desbiez explains why road ecology has become one of the greatest conservation challenges for giant anteaters and demonstrates how wildlife underpasses, wildlife fencing, and other road mitigation structures dramatically reduce wildlife roadkill and wildlife vehicle collisions while improving safety for both people and wildlife.
Beyond species research, this episode highlights innovative examples of community conservation and community-based conservation. Learn how ICAS works with ranchers, indigenous communities, and beekeepers to promote restore habitats, reconnect fragmented landscapes, and develop practical conservation solutions that benefit both biodiversity and local livelihoods. These projects demonstrate how One Health, conservation education, community engagement, and sustainable livelihoods can strengthen long-term ecosystem conservation.
