Least Concern

Sitatunga

Tragelaphus spekii

A semi-aquatic antelope so elusive, it was once believed to be extinct in Ghana.

Sitatunga Overview

The sitatunga is a unique, wetland-dwelling antelope found across sub-Saharan Africa. Adapted for life in the water, this elusive species was once believed by science to be extinct in Ghana. Here, its only population exists in the Avu Lagoon. 

Conservation status

The sitatunga is classified as Least Concern globally, however, in West Africa, habitat loss and severe habitat fragmentation, as well as long-term changes to water levels, are all challenges for sitatunga. In Ghana, there is only one known population. 

Sitatungas are wetland species, living in thickly vegetated swamps, marshes, and seasonally flooded forests. They rely on their wetland habitat for everything, from feeding and resting to escaping from predators.

Found across more than 25 African countries, sitatungas range from West Africa through Central and East Africa. In Ghana, the species exist only in the Avu Lagoon Community Protected Area – one of its most vulnerable populations. 

Habitat loss resulting from bushfires, deforestation and expansion of farmlands into corezones combined with overhunting outside of protected areas is driving sitatunga decline in West Africa.

About Sitatunga

This semi-aquatic mammal is built for the wetland, and can be nearly invisible within it – they’re known to submerge completely underwater when threatened. They are one of Africa’s most specialized and unique antelope species. 

What it is

The sitaunga is a medium-sized antelope; males are considerably larger than females, with long, twisting horns and a grayish-brown coat. Females are reddish-brown with no horns and white stripes. They have a shaggy, oily coat that serves as a waterproof layer to keep them warm in the water.

Where it lives

Sitatungas inhabit thickly vegetated swamps, marshes, and flooded forest across sub-Saharan Africa. They move through tunnelled pathways in tall reeds, rarely venturing onto firm ground. Because swamps provide a year-round food supply, sitatungas have small home ranges. 

Key characteristics

The sitatunga’s long, splayed hooves are one of its most distinctive features. Their hooves are well designed for muddy, vegetated swampland, but make this antelope clumsy and vulnerable on firm terrain. They are slow yet strong swimmers capable of covering several miles, using mounds of floating vegetation to take breaks.

Why it's unique

The elusive sitatunga was long assumed extinct in Ghana by science, despite persisting locally and being well known as “tsimese.” Although never scientifically recorded in the country, its former presence had been inferred from populations in neighbouring Togo that disappeared by 1952, leading to its presumed extinction. In 1998, its continued presence at Avu Lagoon was confirmed through local hunters’ knowledge and the cultural practice of depositing sitatunga horns at hunting shrines. 

Why This Species Matters

This semi-aquatic antelope plays a role in maintaining the health of the wetlands. In Ghana, where the species exists in a single lagoon, its survival is also a measure of the health of one of West Africa’s freshwater wetlands, and losing it would mean the decline of this important ecosystem. Protecting the sitatunga and its critical habitat equally gives protection to a wide range of wildlife including birds, fish, monkeys, reptiles, rodents and insects within the ecosystem.

The Challenges & Threats

Sitatungas are easily caught by snares set along their regular pathways through the wetland, making hunting pressure a persistent threat outside of protected areas. In Ghana, habitat loss through wetland drainage, water quality due to agriculture encroachment, run-off from fertilizers and pesticides and long-term changes to water levels compound their risk, further fragmenting this already isolated population from breeding with others. 

How the Wilder Institute Is Helping

The Wilder Institute works with local communities and partners across the Avu Lagoon Community Protected Area to monitor and protect Ghana’s only sitatunga population. Strengthening the social-ecological resilience of the lagoon is an essential part of the Avu Lagoon Community Wetlands Program, because lasting conservation means improving livelihood security and natural resource governance for the communities at its centre. 

Reintroduction

We aim to maintain and grow Ghana’s only sitatunga population while building the regional knowledge needed to increase connectivity across West Africa’s other populations.

Partnerships

The Wilder Institute’s partnerships combine community governance, scientific expertise, and government support to protect both the sitatunga and the people who share their habitat.

Habitat Protection

The Wilder Institute aims to improve overall lagoon health by supporting ranger salaries, training, and equipment to strengthen wetland monitoring, collaborate on climate-smart agriculture projects to find ways to reduce the usage of fertilizers and pesticides, and protection of sitatunga’s habitat across the Avu Lagoon Community Protected Area.  

Community Work

Agreed conservation measures have an economic cost for the 17 communities of Ghana’s Avu Lagoon. We work with local partners to develop sustainable, ecologically sound livelihoods that help communities meaningfully engage with sitatunga’s conservation.

Impact

Ghana’s sitatunga population was once thought to be lost. Today, active conservation and community partnership are helping protect the sitatunga and the wetland ecosystem it depends on.

Habitat & Range

The sitatunga is found in wetlands across more than 25 African countries.
