In a game reserve, ecosystems are protected and conservation is usually key. Indigenous wildlife in its natural habitat help in providing an environment where growth in numbers at a natural rate can occur.
Some game reserves contain more than one ecosystem, sometimes even five, ranging from valley bushveld, savannah grassland and fynbos to riverine forest and acacia woodland; this provides a dramatic improvement on the types of wildlife that are present and the numerous species of birds that thrive on in these environments.
