From the cliffs of Gansbaai to the streets of Cape Town, residents are being invited to step outside, look closer, and document the natural world around them as part of the City Nature Challenge, a global citizen science initiative taking place this Freedom Day long weekend from 24 to 27 April 2026.
The annual challenge sees cities across the world competing — and collaborating — to record as many species of plants, animals and fungi as possible over a four-day period. It includes 20 South African cities of which six are in the Western Cape. But beyond the numbers, the aim is simple: to reconnect people with the biodiversity that exists all around them, even in the most unexpected places.
A strong showing for the Western Cape
This year, the Western Cape is well represented, with participation across:
- Overstrand (including Hermanus, Gansbaai, Stanford and Kleinmond)
- The broader Overberg region
- Cape Town, one of Africa’s most active City Nature Challenge hubs
In the Overstrand, a dedicated project invites residents and visitors to record “every living thing” within the municipality’s borders — from fynbos species and coastal birdlife to marine organisms in rock pools.
For those in the wider Overberg, observations still count towards regional and national biodiversity datasets, contributing to a growing picture of South Africa’s natural heritage.
From garden sightings to coastal discoveries
Participation requires little more than curiosity and a smartphone.
Using the iNaturalist app, participants can photograph any wild organism they encounter — whether it’s a flowering fynbos shrub, a beetle crossing a path, or a seabird riding the wind. Even a walk through your garden or along a familiar trail can yield surprising discoveries.
In areas like the Overberg, the potential is especially rich. The region forms part of the Cape Floral Kingdom, one of the most biodiverse ecosystems on earth, while its coastline supports a remarkable array of marine life.
Citizen science with real impact
Every observation uploaded during the challenge contributes to a global database used by scientists, conservationists and policymakers.
The data helps:
- Track biodiversity trends
- Identify species distributions
- Support conservation planning
In this way, a simple photograph becomes part of a much larger effort to understand and protect the natural world.
A different way to spend the long weekend
With the challenge coinciding with the Freedom Day long weekend, it offers a timely opportunity to explore the Overberg at a slower, more attentive pace.
Whether it’s a morning walk along the cliffs, an afternoon in a nature reserve, or time spent noticing the small details in your own backyard, the City Nature Challenge turns everyday encounters into moments of discovery.
And in a region where biodiversity is both abundant and under pressure, paying attention may be the most meaningful act of all.
