In the third year of this 7-year project examining the issues facing the planet’s most threatened ecosystems, Dr. M. Sanjayan visits the Maldives to take an in-depth look at coral reefs and the urgent efforts to help them survive climate change.

Professor Peter L. Harrison from Southern Cross University and his team use specialized nets to capture precious coral spawn before it drifts away on the current. This ingenious device allows the spawn, a vital mixture of eggs and sperm, to rise to the surface, where it's gently caught, preserving the genesis of entire coral reefs.

Professor Steve Simpson from Bristol University, UK, plays the sounds of a healthy reef to baby coral nurseries. These sounds will later guide the coral to settle in ideal locations. This innovative approach, on an industrial scale, marks a giant leap toward coral reef restoration, blending science, engineering, natural history, and conservation on a grand scale.

Coral reefs face a crisis with stony coral tissue loss disease, but there's hope in alternative treatments. Dr. Erinn Muller is testing pioneering approaches to save these precious ecosystems. Each rescue forges a path to a healthier future, driven by the belief that a decade from now, we'll be in a much better place in the fight to protect our coral reefs.

Introducing Floaty Boat, a remotely operated vehicle designed to streamline coral larval restoration efforts. Once coral spawn matures into larvae, they're delicately poured into a 100-liter bladder. Floaty Boat employs a larval-friendly pump to transfer them without harm. Equipped with a real-time substrate assessment camera, Floaty Boat revolutionizes coral restoration with precision and care.

In the third year of this 7-year project examining the issues facing the planet’s most threatened ecosystems, Dr. M. Sanjayan visits the Maldives to take an in-depth look at coral reefs and the urgent efforts to help them survive climate change.

Conservationist, M. Sanjayan learns the traditional method for starting controlled wildfires with the Kiwirrkurra community of Australia's remote Gibson Desert. These small managed burns protect against mega-fires by creating natural breaks and removing highly flammable growth.

Changing Planet revisits the Onçafari team in the Pantanal, Brazil. This team is collecting vital data that could help protect Brazil’s top predator, the jaguar.

Conservationist M. Sanjayan visits the Kiwirrkurra community in a remote part of Australia's Gibson Desert. A number of the Kiwirrkurra community grew up as truly nomadic hunter gatherers. On his visit, Sanjayan learns how the Kiwirrkurra hunt feral cats which in turn, helps preserve to Australia's native species.

In the Australian Outback, M. Sanjayan witnesses the impact that invasive camels have made to the natural balance of the Australian ecosystem. Sanjayan begins to understand exactly how urgent the state sanctioned cull of feral camels was 15 years ago.

In the Maldives, Professor Steve Simpson has devised a system that uses the sounds of the reef to help restore them.

In California, the reintroduction of North America's largest rodent, the beaver, brings resilience to wildfires. A fact known for centuries by the Tule River Tribe, and explained here by eco-hydrologist Dr. Emily Fairfax.

Dr. Niels Martin Schmidt's team are monitoring muskoxen in northeast Greenland. Muskoxen are in serious decline and they play a key role in the health of the Arctic tundra and its ability to capture carbon.

M. Sanjayan investigates the biodiversity around Cairns Airport and encounters the infamous cane toad. This amphibian has wreaked havoc on the biodiversity of Australia by eating its way through many important native species.

Changing Planet revisits six of our planet's most vulnerable ecosystems and catches up with truly inspiring scientists and local experts fighting to safeguard their communities and wildlife, and charting the progress of their game-changing environmental projects. Join conservation scientist Dr. M. Sanjayan to meet new faces who’ll deepen our understanding of these habitats.

Join conservation scientist Dr. M. Sanjayan for the beginning of an ambitious 7-year project, a global environmental health check of six of Earth’s bellwether biomes. From the Arctic to the Amazon, these vulnerable habitats are changing, revealing surprising animal behaviors as species adapt. On his journey he meets the inspiring scientists and communities working to bring about positive change.

M Sanjayan joins a team from the Tsavo Trust as they monitor the seasonal movement of big tuskers who are particularly vulnerable to poaching. They see the effects of drought firsthand.

M Sanjayan visits the Voi elephant orphanage and learns about the impact of drought on the local elephant population.

M Sanjayan learns about beekeeping in Kenya and finds out about the environmental and economic benefits to the local Maasai community.

M Sanjayan meets Frankie Myers and takes a look at the Yurok tribe's work to restore the Trinity River as they hope to replenish the once thriving salmon population.
