摘要泥炭沼泽的化石花粉记录被用来提出德克萨斯州中部16,000年的古环境序列。有证据表明，在Fullglacial晚期，德克萨斯州中部被一片开阔的林地落叶林所覆盖，其中有一些针叶树。在晚冰期，这种植被似乎已被拟议的帕克兰植被所取代，主要是草，但仍含有一些树栖元素。最后，在冰后期，更多的树栖元素继续流失，形成了今天的德克萨斯州中部后橡树草原植被。
Abstract Fossil pollen records from peat bogs are used to propose a 16,000‐year paleoenvironmental sequence for central Texas. Evidence suggests that during the late Fullglacial, central Texas was covered by an open woodland deciduous forest with some conifers present. During the Lateglacial, this vegetation appears to have been replaced by a proposed parkland vegetation dominated by grasses but still containing some arboreal elements. Finally, during the Postglacial period there was a continued loss of more arboreal elements resulting in the establishment of the central Texas Post Oak Savanna vegetation of today.
