Bamboo is a group of perennial evergreens in the true grass family. Giant bamboos are the largest members of the grass family with many types.
Bamboo are found in diverse climates, from cold mountains to hot tropical regions such as East Asia, Northern Australia, thru India to Himalayas. They also occur in sub-Saharan Africa, and in the Americas from the Mid-Atlantic United States, south to Argentina and Chile.
Bamboo is one of the fastest-growing plants on Earth; it has been measured surging skyward as fast as 100 cm (39 in) in a 24-hour period. Primarily growing in regions of warmer climates during the Cretaceous period, vast fields existed in what is now Asia.
Bamboo culms are ready for harvest and suitable for use in construction within about 3 – 7 years.
Soft bamboo shoots, stems, and leaves are the major food source of the Giant Panda of China, the Red Panda of Nepal and the Bamboo lemurs of Madagascar. Rats will eat the fruits as described above. Mountain Gorillas of Africa also feed on bamboo and have been documented consuming bamboo sap which was fermented and alcoholic; chimps and elephants of the region also eat the stalks.
