Harvesting of Phyllostachys Pubescens does not threaten the higher altitude habitat of panda bears who feed on other species of bamboo
Bamboo is a plant with single seed leaves and therefore does not increase in thickness as trees do (plants with twin or multiple seed leaves). Bamboo has only one annual ring and the shoot comes in the final diameter/shape out of the root. Within only 2-4 months Phyllostachys Pubescens reaches its maximum height of 40 m. Phyllostachys Pubescens turns into wood after 5 to 8 years and can be harvested. By then the shoot has become dead weight and the plant benefits from its removal. The bamboo forest is regenerated every 8 years without having to be reforested.About 10 tons of bamboo can be harvested per hectare and year. In 35 years a single plant of Phyllostachys Pubescens can yield a cane length of 15 kms. Because of its vegetation period generates new clumps growing out of the roots bamboo raises its bio mass by 30 % per annum. An average pine forest at a medium growth location for comparision produces only 4 tons. A European deciduous forest raises its bio mass by 2-3 % per annum. The average substance production of bamboo is 25 times higher that that of timber (weight per ground space and year). Soft timber takes 10-15 years and hard timber even 50-150 years to grow.
