Slide 21: Test 2: + herbivores, carnivores
If herbivores and carnivores are added into the system, the system is still stable, but not yet equilibrated in one century. Initially, coarse grazers (which are currently the dominant animal biomass component of the savanna system), Increase with the grass component of the ecosystem. However, browser numbers initially expand, and then decrease slowly as the proportion of the ecosystem given over to grassland increases. The carnivore population will also likely increase (tracking the growth in browser numbers), and then follow a gradual decrease as it becomes prey limited. It must be noted that all these models assume an unmanaged landscape with little or no human interaction.
