Kenyan and Tanzanian governments are conducting a joint aerial count of elephants and other large mammals in the shared ecosystem of the Amboseli- West Kilimanjaro and Natron- Magadi landscape. The census will cover a 25,623 sq km area including 9,214 sq km of the Amboseli area, 6348 sq km of the Namanga-Magadi areas in south-western Kenya and 3,013 sq km of the West Kilimanjaro and 7,047 sq km of the Natron areas in North Tanzania.
