Bamboo forest and its secondary vegetation
The Bamboo forests is practically monophytic , in Kahuzi biega national park its found between 2300 and 2600m , bamboo forests has minimum annual requirement of 2000 precipitation , this bamboo stands between 6-15m high and occasionally reaches even 20m . Every 30 to 40 years these plant flowers collectively over large areas and then die, clearing and cultivation of land enables the bamboo forests to spread over large areas. Therefore great stretches of bamboo forests seen today are the consequence of human activities. In the rainy seasons the young bamboo shoots constitute a favourite food for both the gorillas and the chimpanzee in Kahuzi Biega national Park.
