A wetland wild cat living inside the city

The Urban Fishing Cat Conservation Project studies how fishing cats persist in Colombo's fragmented wetland-urban landscape, where they face risk, and how conservation action can support both the species and the city's remaining wetlands.

Remaining wetlands

15%

of Metropolitan Colombo remains wetland.

These wetlands store floodwater, support biodiversity, and provide habitat for fishing cats and other urban wildlife.

Meet the species

1

highly urbanised fishing cat population documented in central Colombo.

Fishing cats are strongly associated with wetlands and are mostly active after dark, which is why many residents live near them without ever seeing one.

Urban wetlands

Wetland conservation supports both wildlife and the city

Colombo's wetlands are part of the city's ecological infrastructure. They store and slow stormwater, filter water, support biodiversity, and connect the remaining habitat patches used by urban wildlife.

For fishing cats, conservation cannot stop at protected marshes. It also depends on canals, wetland edges, gardens, road crossings, and the routes that allow animals to move through the city.

What wetlands do

Four ways Colombo's wetlands support the city

Flood regulation

Urban wetlands temporarily store and slowly release stormwater, reducing flood risk in low-lying parts of the city.

Water quality

Wetland soils and vegetation help trap sediment and filter polluted water as it moves through the urban drainage system.

Biodiversity

Colombo's wetlands support a high diversity of plants and animals, including fishing cats and other wetland-associated species.

Connectivity

Canals, wetland edges, gardens, and road crossings shape how wildlife moves through the city.

A Colombo-based research programme

Field research in Colombo's wetland-urban landscape

We combine camera traps, GPS collars, field surveys, mortality records, and public reports to understand how fishing cats use Colombo's wetlands, road edges, gardens, canals, and connected green spaces.

Support the work

Help sustain long-term fishing cat research and wetland conservation in Colombo

Support helps fund camera traps, field surveys, public reporting, education work, and the monitoring needed to guide conservation action.

Sightings, roadkill records, and other public reports help identify where fishing cats occur and where they may be exposed to risk.
