Solomon Morris Makau checks the fallen tree for snakes before he wraps a tape measure around the trunk. The early morning sun is overwhelming in the dryland forests of the Kasigau corridor, which separates the east and west Tsavo national parks in southern Kenya. Two guards keep watch for elephants and lions. There is little sign of green among the sprawling acacias, which stand silently in their punishing wait for the end of the dry season. Despite the threat from puff adders, Makau and his team have a job to do: measure the trees and shrubs in this 50 sq metre area to calculate their growth and change in carbon stock.
“This one is lying dead,” says Makau, of one of the trees pushed over by elephants – but tens of thousands around it are still alive, stretching out in the distance as far as the eye can see.
