2. Ewaso Ng’iro River: Lifeline of Samburu
The Ewaso Ng’iro River is the most important water source in Samburu, sustaining wildlife and local communities.
Why is the Ewaso Ng’iro River Important?

3. Samburu’s Elevation: How It Affects Wildlife
Samburu National Reserve sits at an elevation of 800 to 1,230 meters (2,600 to 4,000 feet) above sea level.
How Elevation Shapes the Ecosystem
🏔 Lower Elevations (800-1,000m) – Hotter, drier areas with thorny bushes, acacia trees, and open savannahs.
🏔 Higher Elevations (1,000-1,230m) – Slightly cooler areas with denser vegetation, attracting herbivores.
Wildlife & Elevation Connection
- Elephants & Buffaloes stay near the Ewaso Ng’iro River.
- Leopards prefer rocky outcrops in higher elevations.
- Giraffes & Grevy’s Zebras roam lower-altitude savannahs.
🔹 Tip: The best panoramic views of Samburu’s diverse landscapes are from Koitogor Hill (1,230m).
4. How Samburu’s Wildlife Survives Droughts
Samburu faces frequent droughts, forcing animals to develop remarkable survival strategies.
Wildlife Adaptations to Drought
🐘 Elephants – Dig for underground water in dry riverbeds.
🦒 Giraffes – Can survive without drinking water for days, relying on moisture from leaves.
🦓 Grevy’s Zebras – Travel long distances in search of water, unlike common zebras.
🦁 Lions & Leopards – Hunt near shrinking waterholes, where prey is most vulnerable.
Effects of Drought on the Ecosystem
🔥 Longer dry periods – Rivers dry up, forcing wildlife migrations.
🔥 Increased competition for water – Leads to more predator-prey interactions near water sources.
🔥 Threat to plant life – Some acacia trees lose their leaves, affecting herbivores.
🔹 Tip: Visit during dry season (July – October) to witness dramatic survival interactions near water sources.
