Why are Acacia Trees dependent on Giraffes?

One study found the growth of acacia trees depended on herbivores. When the trees were protected from herbivores, including the giraffe, they produced less nectar. It turns out they this nectar provided food for ants who defended them from pests like wood-boring beetles. Also Giraffe's eat the tree seeds and when they defecate the seeds fall into new places, growing more trees.
