阿尔博尔兹山脉北方斜坡小沼泽泥炭的花粉分析（海拔550 m）在伊朗里海中部森林的一次调查揭示了上个千年森林和湿地植被的变化。森林，主要是桤木和鹅耳枥发生在几乎整个时期。栎属、榆属和Parrotia不太常见，而水青冈属、枫杨属、槭属和柿属的变化可能是人为干扰和/或气候变化的结果。泥中粘土沉积的两个阶段可以追溯到“中世纪气候异常”（公元1100年）和“小冰期”（公元1560-1600年）的开始。虽然在整个上个千年中，该区域似乎一直存在人类活动，但国家行动方案价值观的增加表明，自世纪初以来，人类干预有所加强。
Pollen analysis of the peat in a small mire on the northern slope of the Alborz Mountains (550 m a.s.l.) in the Central Caspian forests of Iran reveals changes in forest and wetland vegetation during the last millennium. A forest, principally of Alnus and Carpinus occurred over almost the whole period. Quercus, Ulmus and Parrotia were less common, while Fagus, Pterocarya, Acer and Diospyros fluctuated as a probable result of human interference and/or climatic change. Two phases of clay deposition in the mire can be dated to the `Mediaeval Climatic Anomaly' (AD 1100) and the beginning of the `Little Ice Age' (AD 1560—1600). Although human activity seems to have persisted in the region during the whole of the past millennium, increased NAP values point to intensified human interference since the beginning of the nineteenth century.
