伊比利亚半岛中部几乎没有关于全新世植被和气候历史的放射性碳定年记录。已灭绝和活跃的凝灰岩形成地点位于阿尔卡拉斯山脉的西北边缘。tufa通常与动植物的遗迹密切相关，在El Jardin和Alcaraz定居点附近的两个灭绝的系统已经产生了跨越过去6000年的环境历史记录。记录表明，现今的沉积制度和植被是人类活动引起的，并可能追溯到约2700年BP。在此之前，橡树为主的灌木（mattoral）分布广泛。在大约5000年前，气候似乎相对潮湿，可能更凉爽，这两个地点的集水区比今天的树木更多。
The central part of the Iberian Peninsula has few radiocarbon dated records of vegetation and climatic history for the Holocene. Extinct and active tufa-forming sites occur along the northwestern margin of the Sierra de Alcaraz. Tufas are often closely associated with the remains of plants and animals, and two extinct systems near the settlements of El Jardin and Alcaraz have yielded a record of environmental history that spans much of the last 6000 years. The record indicates that the present-day sedimentological regime and vegetation are human-induced, and probably extend back to about 2700 yr BP. Before this date, oak-dominated scrub (mattoral) was widespread. Prior to around 5000 yr BP the climate appears to have been relatively humid, and possibly cooler, and the catchments for the two sites were more wooded than today.
