As daybreak breaks over Taita Hills Wildlife Sanctuary, the expansive Tsavo panorama in Kenya awakens. Spanning over 48,000 sq. kilometers – practically twice the dimensions of Rwanda – the Tsavo panorama’s huge savannah grasslands, volcanic hills, and riverine forests host roughly one-fifth of Kenya’s African lion inhabitants. Lions in Tsavo face mounting threats, together with escalating human-wildlife battle, habitat loss and fragmentation, insufficient prey, and poaching, amongst others.
In September, Douglas Kamaru, an African Wildlife Basis (AWF) Charlotte Fellow and Ph.D. candidate on the College of Wyoming, launched into a mission to collar 5 lions in Tsavo. That is a part of a examine inspecting prey depletion and its cascading results on lions within the panorama. Utilizing GPS collars, Kamaru goals to collect real-time information that may mitigate human-lion battle and inform efficient conservation methods.
After days of affected person monitoring, Kamaru, accompanied by rangers and native conservancy scouts, noticed a pleasure of three lionesses with six cubs hid throughout the tall grass and shrubs. With overcast morning climate blanketing the conservancy, their tawny coats blended seamlessly with the golden savannah, embodying nature’s camouflage.
Guided by an skilled Kenya Wildlife Service veterinarian, the staff drove steadily towards the pleasure, the Land Cruiser’s engine purring softly to keep away from startling the lions. Halting at a respectful distance, the veterinarian raised the tranquilizer dart rifle, his focus sharp and unwavering. With a exact shot, the dart hit the lioness on her left rib with pinpoint accuracy. Instantly her pleasure scatters.
Because the sedative started to take impact, the staff moved with pace, blindfolding the lioness to attenuate her stress. Working fastidiously, the staff helped Kimaru file important information—her weight, enamel situation, and paw dimensions to assist monitoring through the years. Lastly, the staff secured a GPS collar round her neck, a tool designed to disclose her actions, looking patterns, and interactions throughout the ecosystem.

After 40 minutes, the process concluded with the administration of a reversal drug. From a protected distance, the staff watched because the lioness woke, reoriented herself, and rejoined her pleasure.

Why Collaring Lions Issues
The low lion density in Tsavo – roughly 1.8 people per 100 sq. kilometers – is a trigger for concern. Such shortage signifies potential challenges with prey availability and habitat high quality.
“Not a lot is at present identified about Tsavo’s lions, which is why we’re becoming them with GPS collars,” Kamaru defined. “The collars will present high-resolution information on motion and habitat use, permitting us to find out their dwelling ranges and observe their actions. On this space, we all know of about 4 prides, together with the one we simply collared.”
Measuring the lioness claws.
“Prey depletion and land degradation could also be having a domino impact on the lions in Tsavo,” Kamaru famous. “As prey turns into tougher to seek out, lions could journey larger distances, growing the probability of human-lion battle. This battle typically results in retaliatory killings, additional threatening the inhabitants.”
GPS collars are revolutionizing wildlife conservation by offering real-time information. These collars not solely observe the lion’s actions but additionally incorporate geo-fencing alerts that notify rangers when collared lions method human settlements. This permits rangers to warn communities and deploy scouts to forestall potential conflicts.
Philip Muruthi, AWF’s Vice President for Species Conservation and Science, underscored the importance of this method. “Understanding the place lions roam, discover mates, and hunt permits us to develop and implement data-driven land-use plans with stakeholders, together with native communities, conservancies, the personal sector, and authorities authorities to steadiness conservation and human wants,” he mentioned.
AWF has efficiently carried out comparable collaring initiatives in Tanzania’s Maasai Steppe, LUMO conservancy in Tsavo, and Zimbabwe’s Center Zambezi, with promising outcomes in decreasing human-lion encounters and fostering coexistence.
Regardless of being Kenya’s second-largest lion inhabitants stronghold after Maasai Mara, Tsavo is struggling to fulfill the standards of a viable lion stronghold—outlined as a habitat with over 500 lions and a secure or rising inhabitants.
“Our aim is to revive Tsavo as a lion stronghold now and in the long run,” Kamaru emphasised. “This analysis is essential as a result of it straight informs administration methods and insurance policies for higher conservation of lions and their prey.”
As apex predators, lions are important for sustaining ecological steadiness. They regulate prey populations, stopping overgrazing and preserving biodiversity. Nevertheless, with solely about 24,000 lions remaining in Africa—a 75 p.c decline over the previous 50 years—the species is classed as susceptible by the Worldwide Union for Conservation of Nature (IUCN).
“With out lions, complete ecosystems can collapse,” Kamaru warned. “Whereas lions are our major focus, we’re additionally learning different giant carnivores, reminiscent of leopards and cheetahs, to know broader conservation challenges.”
Muruthi provides, “Collaring will enable us to higher perceive lion conduct, together with predation, and to estimate numbers.”

Compounding Threats: Local weather Change and Human Exercise
Conservation in Tsavo is additional sophisticated by local weather change, significantly recurring droughts that exacerbate water shortage and vegetation loss. Throughout dry seasons, livestock from neighboring areas typically encroach into Tsavo, intensifying competitors for restricted assets and accelerating land degradation.
“Local weather change exacerbates these challenges,” Kamaru defined. “Overgrazing by livestock depletes vegetation, resulting in habitat loss for wildlife. This ripple impact strains ecosystems and reduces prey availability for predators like lions.”
Muruthi added, “We should reduce the price of residing with lions for native communities, making certain a future the place lions, their prey, individuals, and the ecosystem can thrive.”
Collaborative Conservation for a Higher Future
Collaring initiatives like this one in Tsavo are pricey however important for conservation. Kamaru acknowledged AWF’s help in facilitating this work. “With out companions like AWF, securing the assets wanted for this analysis could be extremely difficult,” he mentioned.

Up to now Kamaru has efficiently collared 4 lions within the Taita Hills Wildlife Sanctuary and the encompassing ecosystem. The lions can be monitored for the following two years as a part of the analysis examine.
This examine has been made doable via the help of the College of Wyoming, Merely Southern, KWS, Wildlife Analysis and Coaching Institute (WRTI), Taita Taveta county authorities, personal conservancies, and the area people.
Via initiatives like this, AWF and its companions should not solely defending Tsavo’s lions but additionally safeguarding the fragile steadiness of a whole ecosystem.
