杜鹃属杜鹃属杜鹃属它通常用于东喜马拉雅山区的薪材，然而，就生物量而言，关于该物种的提取速度与其年增量能力之间的关系尚不清楚。在研究区，薪材是主要的能源来源。我们在两个居民点及其附近进行了住户调查和生态调查，以评估薪材消耗和现有的地上生物量OFR。木本植物。根据当地居民的说法，这种树种为家庭薪材需求贡献了20%-25%，而森林调查和对新砍伐的树桩的调查表明，15%的树木被砍伐用作薪材。木本植物。乔木多为幼树，约占林中树种的20%，平均生物量为70.41万×103 kg/hm2−1。研究时计算的砍伐林木生物量为8.71万亿×103kghm2−1。根据目前的提取和增量速度进行的模拟表明，在大多数监测地点，物种未来将处于危急状态。然而，在一些地方，尽管正在进行开采，但生物量仍在增加。结果表明，迫切需要森林管理，第一步可以通过轮伐来实现，使林木能够再生和积累生物量。此外，杜鹃林的枯竭可以通过以杜鹃为主题的生态旅游和提供替代能源的经济发展来减少。
Rhododendron arboreumSm. is commonly used for fuelwood in mountainous regions of the Eastern Himalaya, however nothing is known about rates of extraction versus the annual increment capacity of the species in terms of biomass. In the study area, fuelwood is the major source of energy. We conducted household surveys and ecological surveys in and near two settlements to assess both fuelwood consumption and existing above ground biomass ofR. arboreum. According to local residents, this species contributes 20–25% to household fuelwood requirements, while forest surveys and a survey of freshly cut stumps indicate that 15% of trees felled for fuelwood wereR. arboreum. Trees were mostly young, comprised about 20% of all tree species in the forest, and accounted for 70.41 × 103kg ha−1biomass in average. The biomass of felled trees was calculated as 8.71 × 103kg ha−1at the time of study. Simulation based on the current rates of extraction and increment showed that the species will be in a critical condition in future at most of the monitored sites. In some places however, biomass was found to increase in spite of ongoing extraction. The results indicate that there is an urgent need of forest management which in a first step can be achieved through rotational harvesting that allows forest stands to regenerate and build up biomass. In addition, depletion of rhododendron stands can be reduced by economic development through ecotourism on the theme of rhododendrons, and by providing access to alternative sources of energy.
