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 store and slow stormwater, filter polluted water, support biodiversity, and connect the remaining habitat patches used by urban wildlife.

For fishing cats, conservation depends on more than protected wetlands. 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 use camera traps, GPS collars, field surveys, mortality records, and public reports to study fishing cat movement, habitat use, activity, diet, and risk exposure.

Support the work

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

Support helps fund field equipment, monitoring, public reporting, education work, and the continuity needed for long-term conservation research.

Public reports also help identify where fishing cats occur and where they may be exposed to risk.
