甘贝尔橡树 (Quercus gambelii Nutt.) 在亚利桑那州、科罗拉多州、新墨西哥州和犹他州占地约 350 万公顷。它被认为是重要的薪材资源。适当管理策略的设计需要有关这些林分内生物量分布特征的信息。在犹他州对八个甘贝尔橡树小乔木和灌木林（无性系）的生物质成分进行了采样。每公顷无性系的茎密度为 5,000 至 34,000 个。平均茎直径从 36 毫米到 117 毫米不等。包括枯枝在内的活茎平均重 4,992 克，而直立枯枝平均重 1,347 克。每公顷的活生物量平均为 124,388 公斤，其中包括 40,702 公斤树干。地上与地下活生物量的比例异常低——44:56。每公顷克隆的地上和地下总生物量（包括碎屑）为 184,292 千克。森林科学。 32：234-242。
Gambel oak (Quercus gambelii Nutt.) occupies approximately 3.5 million ha in the states of Arizona, Colorado, New Mexico, and Utah. It is becoming recognized as an important fuelwood resource. Design of appropriate management strategies requires information on the biomass distribution characteristics within these stands. Biomass components of eight Gambel oak small tree and shrub form stands (clones) were sampled in Utah. Stem densities ranged from 5,000 to 34,000 per ha of clone. Mean stem diameters varied from 36 to 117 mm. Live stems averaged 4,992 g including dead branches, while standing dead stems averaged 1,347 g. Live biomass per occupied hectare averaged 124,388 kg including 40,702 kg of bole. The ratio of aboveground to belowground live biomasses was unusually low—44:56. Total aboveground and belowground biomass including detritus was 184,292 kg per hectare of clone. Forest Sci. 32:234-242.
