Trees of Africa form a quintessential part of the landscape. We can't envisage the wonders of the grassy savannas without their being dotted here and there by the flat-topped acacia trees. Giraffes stretch up to nibble at thorny twigs. A leopard hauls her hard won prey up to the safety of the branches. An elephant grinds his itchy rump against the bark of a baobab. A herd of kudu disappear into the shadows cast by yellow-barked fever trees. Mere vignettes cannot do more than pique the imagination but we can envisage how the lives of trees and those of animals are so intimately intertwined as to be inseparable.
