Wetland Rehabilitation at Haller Park – Restoring Life to Water

Wetland Rehabilitation at Haller Park

Haller Park in Mombasa, Kenya, is more than just a wildlife sanctuary — it’s a global model of ecological restoration. One of its greatest successes is the creation and rehabilitation of wetlands in a place where none existed before.

By transforming abandoned quarry pits into wetland ecosystems, Haller Park restored natural water cycles, created habitats for countless species, and demonstrated how wetlands can fight climate change and protect biodiversity.

Why Wetlands Matter

Wetlands are among the most productive ecosystems on Earth. They:

  • Filter water naturally, removing pollutants through plants and microbes
  • Provide habitats for fish, amphibians, birds, and reptiles
  • Protect coastlines by absorbing floods and preventing erosion
  • Support biodiversity by acting as breeding grounds for aquatic life


In Kenya, where wetlands face constant threats from development and pollution, Haller Park’s wetlands prove how restoration can succeed.

From Quarry Pits to Living Wetlands

When restoration began, the quarry pits left behind by limestone mining filled with stagnant rainwater. Instead of draining them, ecologists transformed them into wetlands by:

  1. Introducing aquatic plants like papyrus and reeds
  2. Adding fish to control mosquito larvae
  3. Allowing hippos and crocodiles to play their natural role in aquatic balance
  4. Connecting wetlands with aquaculture systems to recycle nutrients


This created a self-sustaining wetland network, improving both water quality and biodiversity.

Wildlife in the Restored Wetlands

Haller Park’s wetlands are now home to a wide variety of species, including:

  •  Fish such as tilapia and catfish
  • Birds like herons, kingfishers, storks, and egrets
  • Reptiles including Nile crocodiles and terrapins
  • Amphibians such as frogs and toads
  • Insects like dragonflies and damselflies that help control pests

The wetlands also attract migratory birds, making the park a stopover for species traveling along the East African flyway.

Ecosystem Services of Wetland Rehabilitation

The benefits of Haller Park’s wetlands extend far beyond the park itself:

  •  Water purification: Wetland plants filter harmful chemicals
  • Climate regulation: Wetlands store large amounts of carbon
  • Sustainable food: Integrated with aquaculture for fish farming
  • Tourism & education: Birdwatchers, researchers, and students learn from these living classrooms

Education & Research in Wetland Conservation

Haller Park’s wetlands are used by schools and universities for research on:

  • Water quality monitoring
  • Aquatic species diversity
  • Wetland plant adaptation
  • Climate resilience

Visitors can join guided tours to learn how these ecosystems function and why wetlands are critical for Kenya’s coastal environment.
