The Think Wildlife Podcast

In an increasingly fragmented world, how do we conserve the ecological connectivity of large landscapes? Although the traditional protected area model has been crucial in the recovery of landscapes around the world, these are rarely sufficient for the conservation of wide-ranging species, which require large, connected landscapes.In this episode of the Think Wildlife Podcast, Anish Banerjee speaks with Gabriel Oppler, International Policy and Partnerships Specialist at the Center for Large Landscape Conservation (CLLC), about the science and policy of landscape connectivity.Gabriel explains what wildlife corridors are, how they relate to the wider permeability of a landscape, and why corridor design depends on the species being conserved. The conversation distinguishes structural connectivity- how habitat is arranged- from functional connectivity - how animals actually move through it. These landscape ecology considerations are central to effective wildlife corridor conservation.The discussion then turns to conservation policy: from Ecuador’s wildlife corridor model, international conservation policy frameworks, the barriers to their implementation, and the importance of transboundary landscape conservation. Gabriel also discusses wildlife crossings and the role of infrastructure planning in large landscape conservation. From biological corridors to transboundary landscape conservation, this episode explores what it takes to support large landscape conservation and ecological connectivity.

What does it take to protect Africa’s natural heritage across highly fragmented landscapes? In this episode of The Think Wildlife Podcast, Anish Banerjee is joined by Yolan Friedmann, CEO of the Endangered Wildlife Trust, for an in-depth conversation about the conservation of lions, cheetahs, and African wild dogs. Yolan explores the ecological importance of large carnivores, which influence ecological processes and habitat structure by affecting prey populations. Conserving these endangered species therefore helps preserve these trophic cascades and supports broader biodiversity conservation. For Yolan, these species are part of Africa’s natural heritage because they belong to its living ecosystems and hold enduring meaning for the people who share those landscapes. Protecting them therefore involves more than preventing extinction within individual reserves. Large carnivore conservation also depends on maintaining the ecological processes that allow populations to persist: dispersal, the establishment of new territories, breeding and genetic exchange.Yolan explains how habitat fragmentation, fences and expanding human land use restrict those processes. A population may increase inside a protected area while remaining dependent on intervention if its offspring cannot disperse. In South Africa, the Endangered Wildlife Trust responds by carefully selecting and moving cheetahs and African wild dogs between suitable reserves. We discuss how this approach relates to metapopulation conservation, and why Yolan describes it more precisely as managing populations across disconnected reserves.Human–carnivore conflict is another central theme of this discussion. Livestock losses can have severe consequences for households, while game farmers may also view predators as a threat to wildlife-based livelihoods. Yolan discusses using animal tracking and targeted alerts to anticipate conflict, alongside the relationships EWT staff build with farmers and local communities. We consider the distinct needs of cheetahs, the social organization and extensive range requirements of African wild dogs, and the opportunities and setbacks in expanding wild dog ranges.We also examine the particular challenges facing cheetahs and African wild dogs: habitat requirements, genetic management, the social structure of wild canids and the extensive space needed for wild dog packs to disperse. Yolan reflects on the achievements and setbacks of range expansion in South Africa before returning to the episode’s central question: how can endangered wildlife conservation keep Africa’s natural heritage ecologically functional and meaningful for future generations?Time Stamps00:00 Introduction02:14 Evolving Approaches to Endangered Species Conservation 03:23 Threats to Africa’s Natural Heritage05:19 The Role of Large Carnivores and Trophic Cascade07:32 Growing Challenges of Human-Carnivore Conflict09:22 Using Technology to Prevent Conflict 10:54 Building Trust with farmers and communities12:53 The Challenges of Cheetah Conservation: Habitat and Genetic Diversity14:11 Managed Population Approach to Cheetah Conservation15:48 African Wild Dog Ecology and Perceptions18:29 Restoring Wild Dog Populations in South Africa20:42 Why Wildlife Is Part of Africa’s Natural Heritage22:08 Supporting the Endangered Wildlife Trust23:30 Reflections #NaturalHeritage #LargeCarnivoreConservation #BiodiversityConservation #TrophicCascades #MetapopulationConservation #LionConservation #Cheetahs #AfricanWildDog #WildCanids #EndangeredSpecies #EndangeredWildlife #EndangeredWildlifeConservation #EndangeredSpeciesConservation #CheetahConservation Get full access to The Think Wildlife Podcast at anishbanerjee.substack.com/subscribe

How do we secure a future for Asian elephants while ensuring that people living alongside them can thrive? Can human-elephant coexistence become a reality in one of the world’s fastest-changing landscapes? In this episode of the Think Wildlife Podcast, we are joined by Dr. Bibhuti Prasad Lahkar, Programme Secretary and Deputy Executive Director at Aaranyak, where he also leads the Elephant Research and Conservation Division (ERCD). With decades of experience working across North-east India, Dr. Lahkar has become one of the region’s leading voices in elephant conservation, community-led conservation, and landscape-scale biodiversity cosnervation. Growing up in Guwahati, Dr. Lahkar developed a lifelong fascination with wildlife that eventually led him to dedicate his career to conserving Asian elephants, restoring degraded ecosystems, and working alongside communities living at the frontline of conservation. He reflects on his early experiences working in Manas National Park, one of India’s greatest conservation success stories, during a period of political unrest when conservation operations continued despite armed conflict, damaged infrastructure, and limited management capacity. A central focus of this conversation is the growing challenge of human-elephant conflict across Assam and the wider landscapes of North-east India. As forests become fragmented, elephant corridors disappear, and infrastructure expands, encounters between people and elephants have become increasingly common. Dr. Lahkar explains the ecological and social drivers behind rising human-elephant interactions, the tragic annual loss of both human and elephant lives, and why coexistence requires far more than simply responding to conflict after it occurs. Instead, Aaranyak has developed a highly successful model built around community-based conservation. Rather than treating local communities as passive beneficiaries, the organisation empowers villages to become active partners in conservation. Dr. Lahkar explains how community-managed solar fencing, biofencing using Assam lemon, awareness programmes, crop protection, assistance in accessing government compensation, and alternative livelihood initiatives all work together to reduce conflict while improving local wellbeing. These examples demonstrate why long-term community conservation remains one of the most effective pathways towards sustainable human-elephant coexistence. Beyond conflict mitigation, Dr. Lahkar discusses the broader future of Asian elephant conservation. He explores the importance of maintaining habitat connectivity, protecting elephant corridors, improving degraded forests, strengthening coordination between government departments, scientists, NGOs, and local communities, and ensuring long-term political commitment. He argues that successful elephant conservation depends as much on governance and public participation as it does on ecological science. The conversation also explores Dr. Lahkar’s research on Assam’s globally important alluvial grasslands and the restoration of these ecosystems through invasive species removal and improved habitat management. Healthy grasslands support elephants alongside rhinos, wild buffalo, swamp deer, and countless other species, making them essential for megafauna conservation and ecosystem recovery. These restoration efforts also contribute to wider megafauna rewilding, rebuilding resilient landscapes capable of supporting thriving wildlife populations for generations to come. Dr. Lahkar also shares some of the proudest moments of his career, the biggest challenges facing conservation organisations today—including limited skilled manpower and short-term project funding—and why investing in local people remains one of the most effective conservation strategies available. Whether you are interested in wildlife biology, ecology, conservation policy, protected area management, restoration ecology, or sustainable development, this episode provides valuable insights into how science, communities, and governments can work together to secure a future for megafauna while improving the lives of people who share their landscapes.

South Asia’s rivers are among the most biodiverse freshwater ecosystems on Earth, yet they are also among the most threatened. In this episode of the Think Wildlife Podcast, host Anish Banerjee is joined by Dr. Nachiket Kelkar, freshwater ecologist and researcher at the Wildlife Conservation Trust (WCT), to explore the future of river conservation across the Indian subcontinent. The conversation examines why conserving the Ganga and other major river systems requires protecting entire river ecosystems, balancing human livelihoods with biodiversity, and rethinking how we manage freshwater resources. Dr. Kelkar begins by sharing how his fascination with whales and dolphins eventually led him to study one of the world’s most remarkable freshwater mammals—the Gangetic river dolphin. Often called the “blind tiger of the Ganga,” this functionally blind cetacean relies on echolocation to navigate the often muddy waters of the Ganga-Brahmaputra-Meghna-Karnaphuli-Sangu river basins, which span India, Bangladesh, and Nepal. He explains the dolphin’s unique adaptations, conservation status, and why it has become an iconic symbol of Ganga conservation and river biodiversity conservation. The discussion explores whether the Gangetic river dolphin truly functions as an umbrella species for protecting Gangetic river biodiversity. While flagship species can help generate public awareness and political support, Dr. Kelkar explains why conserving freshwater ecosystems ultimately requires protecting fish, turtles, crocodilians, aquatic birds, riparian habitats, and the ecological processes that sustain entire river ecosystems, rather than focusing on a single charismatic species. Studying dolphins in large, dynamic rivers presents unique scientific challenges. Dr. Kelkar discusses innovative survey techniques including double-observer surveys, acoustic monitoring, and population estimation methods that allow researchers to better understand dolphin abundance, behaviour, and habitat use. These scientific tools are essential for monitoring long-term population trends and guiding effective river wildlife conservation. The conversation then turns to the growing threats facing South Asia’s freshwater ecosystems. Dr. Kelkar explains how dams, barrages, river fragmentation, canals, overfishing, bycatch, sand mining, pollution, reduced environmental flows, inland waterways, and proposed river interlinking projects are transforming the ecological character of rivers across the Gangetic plains. These pressures not only threaten the Gangetic river dolphin, but also jeopardise fisheries, ecosystem services, and countless other species that depend upon healthy freshwater habitats. The episode highlights why protecting river biodiversity must become a central component of broader wildlife conservation and biodiversity conservation strategies. Pollution is another major focus of the discussion. Rather than viewing pollution solely as an engineering challenge, Dr. Kelkar argues that lasting solutions require behavioural and cultural change alongside improved governance, wastewater management, and stronger environmental stewardship. He explains why restoring the Ganga is ultimately about changing society’s relationship with rivers as living ecosystems rather than simply treating them as water resources. Dr. Kelkar also introduces the Wildlife Conservation Trust’s Riverine Ecosystems and Livelihoods Programme, which works at the intersection of conservation, fisheries, governance, and community livelihoods. The discussion examines the challenges of coordinating multiple government departments, balancing competing stakeholder interests, understanding different fisheries typologies, and developing practical solutions that benefit both people and freshwater biodiversity. The episode concludes with reflections on Dr. Kelkar’s career, the importance of interdisciplinary conservation science, and practical ways that individuals can contribute to protecting South Asia’s rivers. Whether you’re interested in river ecosystems, river biodiversity, Gangetic river dolphin conservation, Ganga wildlife conservation, freshwater ecology, fisheries management, or environmental policy, this episode offers a comprehensive look at one of the world’s most important—and most threatened—freshwater landscapes.

In this episode of the Think Wildlife Podcast, I am joined by Rushikesh Chavan, Director of The Habitats Trust, one of India’s leading conservation philanthropy organizations. Together, we explore how philanthropy, conservation technology, and systems thinking are transforming biodiversity conservation across India, with a particular focus on marine ecosystems, conservation innovation, and strategic conservation funding. India’s marine ecosystems support extraordinary biodiversity and millions of livelihoods, yet they continue to receive comparatively less conservation attention than terrestrial landscapes. In this conversation, Rushikesh discusses why strengthening Indian marine biodiversity conservation is essential, the ecological significance of coral reefs, and how marine conservation requires an integrated understanding of interconnected ecological, social, and economic systems. The discussion examines The Habitats Trust’s work on coral reef conservation in Lakshadweep, the ecological importance of coral reef ecosystems, and the Sardine Initiative, which seeks to better understand one of India’s most ecologically and economically significant fish species. We also explore the complex relationship between fisheries, livelihoods, ecosystem health, and sustainable resource management within India’s marine environment. A major focus of the episode is the rapidly evolving field of conservation technology. Rushikesh explains how technologies such as remotely operated underwater vehicles (ROVs), artificial intelligence, computer vision, GIS, bioacoustics, and autonomous marine systems are expanding our ability to explore, monitor, and conserve marine ecosystems. Rather than viewing technology as an end in itself, the discussion highlights its role as a practical tool for addressing complex conservation challenges and improving biodiversity research. The conversation also explores the importance of making these technologies and the resulting datasets accessible to researchers and conservation organisations through open collaboration and capacity building. The episode also provides an in-depth overview of The Habitats Trust Grant Program, discussing the philosophy behind conservation philanthropy, funding priorities for lesser-known species and critical habitats, and the challenges associated with financing effective conservation action. Rushikesh reflects on emerging trends in conservation funding, identifies taxonomic groups and ecosystems that remain underrepresented, and discusses how India’s conservation funding landscape can continue to evolve. Finally, Rushikesh shares thoughtful advice for early-career conservationists, emphasizing the importance of systems thinking, interdisciplinary collaboration, technological literacy, and understanding the diverse roles played by governments, NGOs, communities, researchers, corporations, and funding agencies in achieving long-term conservation outcomes. He concludes by reflecting on the reasons for optimism within India’s conservation sector and the opportunities that lie ahead for biodiversity conservation.
