Forty-six camera trap photographs. That is what 15 years of work looks like when it finally pays off. Conservation International and local fishing communities in Cambodia have confirmed the presence of a rare fishing cat in the restored flooded forests of Pursat province, on the shores of Tonle Sap Lake — only the second confirmed record of the species in the entire lake region. It is a moment that signals one of Southeast Asia's most important wetlands is genuinely coming back to life.
**The Lake That Feeds Cambodia**
Tonle Sap is not just any lake. It is the largest freshwater lake in Southeast Asia, and the heartbeat of Cambodian food security. Each year, the Mekong River reverses flow during monsoon season and pushes water backward into Tonle Sap, expanding the lake from roughly 2,500 square kilometres in the dry season to more than 15,000 square kilometres at its flood peak. That seasonal pulse creates the richest freshwater fishery in the world relative to its size, providing protein for tens of millions of people.
But by the early 2000s, Tonle Sap was in serious trouble. Decades of overfishing, wetland clearing, and pollution had decimated fish stocks and degraded the flooded forest ecosystem that supports them. The return of top predators — like the fishing cat — had seemed impossible.
**What Is a Fishing Cat?**
The fishing cat (*Prionailurus viverrinus*) is a medium-sized wild cat found across South and Southeast Asia, adapted specifically to wetland habitats. Twice the size of a domestic cat, it has partially webbed front feet and a thick, water-resistant coat. Its diet is primarily fish — it hunts by tapping the water surface with its paw to mimic insects and attract fish, or by diving in directly.
The species is classified as Vulnerable on the IUCN Red List, with a global population estimated at fewer than 10,000 mature individuals. Records in Southeast Asia are sparse and scattered. The presence of fishing cats in a wetland is considered a strong indicator of ecosystem health — they need abundant fish populations, dense vegetation, and freedom from heavy human disturbance to survive.
Their presence in the Tonle Sap flooded forests, in other words, is not just a conservation win for the fishing cat itself. It is a signal about the state of the entire ecosystem.
**Fifteen Years of Restoration**
The discovery was the result of camera trapping undertaken by Conservation International (CI) in partnership with the Royal Government of Cambodia and 16 local fishing communities. The restoration programme that made it possible began more than a decade ago, when CI and the Cambodian government launched an intensive effort to reverse the decline of the Tonle Sap flooded forests.
The programme focused on several interconnected strategies:
**Community fishing lot dissolution** — returning formerly privatised fishing areas to community management, reducing overfishing pressure **Replanting native flooded forest trees** — restoring the flooded forest habitat that fish and wildlife depend on for shelter and breeding **Invasive species removal** — clearing water hyacinth and other invasive plants that were clogging the lake **Community patrol networks** — engaging local fishers as conservation monitors to deter illegal fishing and wildfire **Sustainable livelihood programmes** — creating economic alternatives to destructive fishing practices
Sony Oum, Country Director of Conservation International Cambodia, described the fishing cat sighting as a testament to what is possible with long-term, community-led conservation. "The fishing cat's return underscores the effectiveness of long-term, science-based wetland restoration and community-led conservation," he said. "It's a sign that nature is healing when we give it the chance."
**46 Photographs That Tell the Story**
The confirmation came from 46 individual camera trap images — the most thorough photographic documentation of the species in the Tonle Sap region to date. The images were captured in the restored flooded forests of Pursat province, where native trees replanted by community workers have now matured sufficiently to provide the dense, wet vegetation the fishing cat requires.
It is only the second confirmed record of a fishing cat anywhere in the Tonle Sap lake area — the first was from nearby restored wetlands in mid-2025. Two sightings in less than a year in a region where the species had not been recorded for generations suggests a small but real population is beginning to establish itself.
**A Lake Recovering**
The fishing cat's return is one signal among many that Tonle Sap's ecosystem is improving. Fish biomass in the lake has been recovering since the community fishing lot reforms. Bird diversity is increasing. The flooded forest — once cleared to the water's edge in many areas — is visibly regrowing.
Cambodia's Ministry of Agriculture, Forestry and Fisheries Minister Dith Tina highlighted that the discovery "demonstrates Cambodia's commitment to conserving, managing, and developing the environment and natural resources, aligning with national policies and global biodiversity frameworks."
It also demonstrates something simpler: that 15 years of consistent, community-supported effort can bring a lake back from the edge. The fishing cat — elusive, precise, built for wetlands — is confirmation that the water is clean enough, the fish plentiful enough, and the reeds thick enough for wild things to return.
