The importance of wildlife corridors for Tsavo’s elephants

Wildlife corridors are essential lifelines that allow animals to move between habitats without human interference. For elephants, these corridors are critical as they facilitate the migration necessary for survival, ensuring access to food, water, and breeding areas.

In the Tsavo Conservation Area, one of the largest elephant populations in Kenya depends on these pathways to thrive. Unfortunately, many of these corridors are threatened by human activities, which could have significant impacts on Tsavo’s elephant population. This article explores the importance of wildlife corridors in general, before delving into those specific to Tsavo’s elephants.

Why wildlife corridors matter

At their core, wildlife corridors are designed to connect separate habitats, enabling animals to move freely between them. For migratory species like elephants, these corridors are crucial for accessing the resources they need. Without them, animals would become isolated in specific areas, leading to overgrazing and degradation of the environment.

Corridors also help maintain genetic diversity, which is key to a species’ long-term health and survival. By allowing animals to interact and breed across wider populations, these pathways prevent inbreeding, which can result in weakened immune systems and other health problems.

Wildlife corridors are also important for reducing human-wildlife conflict. As human populations grow and expand into natural habitats, elephants and other animals often come into direct contact with farms and settlements. By providing designated routes that guide wildlife away from these areas, corridors help minimize the potential for destructive encounters. In regions where elephants traverse farmland, such as Tsavo, this conflict can become deadly, both for humans and the animals themselves.

Key Corridors for Tsavo’s Elephants

Tsavo East-West Corridor

The Tsavo East-West Corridor links Tsavo East and Tsavo West National Parks, forming one of the largest conservation areas in Kenya. For the elephants, this corridor is vital, providing a passage between the parks to access seasonal water sources, food, and mates, all of which are essential for maintaining population health and genetic diversity.

Tsavo is home to 10 recognised Super Tuskers. With less than 30 in the world protecting these creatures and their wildlife corridors is crucial.

However, this corridor faces significant challenges. The construction of the Standard Gauge Railway (SGR), a major infrastructure project, has severely impacted the elephants’ ability to move freely between the parks. Although underpasses were built along the railway to allow wildlife to cross, much of the railway is fenced, forcing elephants to travel longer distances to find these crossings. This disruption has led to increased human-wildlife conflict, particularly in nearby villages like Sagalla, where elephants raid farms as they search for alternative routes.

Kasigau Wildlife Corridor

The Kasigau Wildlife Corridor, nestled between Tsavo East and Tsavo West National Parks, protects around 200,000 hectares of dryland forest. This corridor is critical not just for elephants, but also for a range of endangered species, including lions, cheetahs, and leopards. Its preservation is a result of community-driven conservation efforts supported by carbon credit revenues, which have helped prevent illegal activities like poaching and unsustainable farming.

The success of the Kasigau Corridor is a testament to the power of community involvement. Through carbon credit payments, over 116,000 locals benefit from job creation, scholarships, and access to clean water, all of which have reduced reliance on environmentally destructive practices. This model shows how conservation can work hand-in-hand with human development, benefiting both wildlife and people.

Amboseli Group Ranch Corridor

The Amboseli group ranches corridor consists of six key group ranches: Olgulului/Olararashi, Kimana, Mbirikani, Eselengei, Rombo, and Kuku. Together, these ranches span approximately 1.2 million acres, forming vital wildlife corridors that link Amboseli with the Chyulu Hills and Tsavo West National Parks. This corridor is vital for ensuring that elephants can move between parks to access food and water, particularly during dry seasons when resources become scarce.

The subdivision of Amboseli’s group ranches into private allotments poses a significant threat to the ecosystem, leading to habitat fragmentation and degradation. In 2019, Kenya’s Ministry of Lands opened community lands to adjudication, encouraging the break-up of rangelands into smaller plots. This mirrors the earlier fragmentation of the Kaputei group ranches, which resulted in a steep decline in wildlife populations. Conservationists fear that wildlife, including elephants, will be pushed out of these small, subdivided lands, jeopardizing seasonal migrations and essential corridors. If the Olgulului-Ololarashi Group Ranch (OOGR) follows suit, Amboseli’s migratory routes could face a similar fate, leading to further wildlife declines.

Threats to Wildlife Corridors

The major threats to wildlife corridors in Tsavo and across Kenya are a result of human activity. Encroachment and illegal settlements block natural migration routes, while infrastructure projects, such as roads and railways, create barriers that disrupt wildlife movement. As farming expands, more habitat is destroyed, and the likelihood of human-wildlife conflict increases.

Protecting these wildlife corridors is crucial for the future of Tsavo’s elephants and other species. Organizations like Tsavo Trust are working tirelessly to restore and preserve these corridors, but they need support. By donating to conservation efforts, you can help mitigate human-wildlife conflict, work with local communities, and ensure that these critical migration paths remain open. Every contribution helps safeguard the future of Tsavo’s elephants, ensuring that they can continue to roam freely in one of Africa’s most iconic landscapes.
