Ringal (Hill Bamboo)
Another group of bamboo- A.falconerii (Dev Ringal), A.falcata (Gol Rinagl) A.jaunsarensis (Jamura Ringal) and Thamnocalamus spathiflora (Tham Ringal) occur throughout the temperate forest of the State. Ringal grows on steep mountain slopes, at an elevation of 1800-2400m in the Garhwal and Kumaon Hills. They generally grow as the under-story of oak and rhododendron forests. Ringal is distributed over 66,000 ha in different forest divisions of Uttarakhand. They are usually tufted, gregarious with erect small culms which are conical in shape. The culms attain an average height of 12ft with a diameter of 10-20 mm, with internodes approx. 20 cm apart. The wall thickness varies from 3-4 mm. In general, the leaf is 10 cm long and 1.2 cm broad. The average flowering cycle is about 30 years. The first crop of Ringal begins to emerge around August to September and from February to March it becomes flexible, strong and ready to use. People in the higher altitudes use it in this form to make thatches and ropes. Culms are used for weaving mats and baskets and leaves are used as fodder.
