Elephants knock down the trees so that they can feed on the foliage. They have been doing that since the earth was created and this has never affected the climate.
But it has left Amboseli bare. But that has been worsened by confining the beasts to a closed area due to human interference with migration corridors.Elephants knock down the trees so that they can feed on the foliage.

Without elephants removing the trees/shrubs, the area would turn into a shrubland/woodland and this would reduce the total productivity of the ecosystem since grasses grow best in open areas and produce more biomass per unit area per yr (or per rainy season) than the trees/shrubs. Natural selection selects the most efficient evolution path and it has decided elephants knocking down trees is the best evolutionary path.But it has left Amboseli bare.
