Under cover of night, in the flooded forests of Pursat, Cambodia, a camera trap recorded a ghost.
In the monochrome glow of infrared light, a fishing cat padded along the water's edge before slipping back into the darkness. The species — *Prionailurus viverrinus* — is so rare it borders on myth across South and Southeast Asia. Yet, over the past year, this single adult fishing cat has been photographed dozens of times at the same location.
Its return to Cambodia's Tonle Sap marks a turning point in one of conservation's most patient success stories.
"It's a thrilling discovery," said Sony Oum, who leads Conservation International's work in Cambodia. "But its sighting indicates so much more than just the return of the fishing cat — it's a testament to the hard work of the community to restore their wetlands."
For 15 years, Conservation International, the Royal Government of Cambodia, and 16 local fishing communities have worked to restore Tonle Sap — Southeast Asia's largest freshwater lake and the world's largest inland fishery. Their work involved preventing pollution, stopping overfishing, and removing invasive species: non-native mussels, giant sensitive tree, and water hyacinth that had smothered native habitats.
Today, the partnership has brought more than 1,000 hectares of degraded flooded forest back to life — planting native trees, protecting intact wetland areas, and organising community patrols to stop illegal activity and wildfire.
The fishing cat's return is the clearest sign yet that it's working.
Across Cambodia, most large predators have vanished. In a landscape reshaped by decades of habitat loss and hunting, the quiet reappearance of even a mid-sized carnivore carries outsized meaning.
"The cat's return suggests fish are abundant enough to sustain a hunter," Oum said. "It suggests the flooded forests have regained some of the underbrush that predators need to hide from prey. It suggests that, at least here, the wetlands are recovering."
Fishing cats are natural swimmers — about twice the size of a house cat, with partially webbed paws and flattened ears that form a watertight seal for diving. They wade through wetlands with ease, scooping fish from the shallows or plunging fully underwater to catch a meal. As apex hunters in these ecosystems, they keep fish populations in balance and signal the health of the whole system.
Experts estimate fewer than 10,000 fishing cats remain in the world.
A restored Tonle Sap matters for more than wildlife. More than 1.5 million people live in the area — many in stilt houses and floating villages — and rely on the lake's forests for freshwater, food, and fuelwood. The fishing cat's return signals the resilience of an ecosystem that millions of people depend on.
Some restorations take decades. This one did. And a ghost came home. 🐆
