迄今为止，德国西北部泥炭保存的松树的年轮年表（图1）跨越了公元前6703年至公元前1166年，但仍然存在两个空白。它是在先前构建的德国西北部沼泽橡树年表的帮助下确定年代的，而该年表的较旧部分又使用松树年表确定了年代（图 2），除了之前的公元前 6069 年至公元 931 年之外，现在涵盖了公元前 6628 年至 6178 年。与橡树相比，年代学构建需要大量短命松树的样本，其中许多样本尚未注明日期或日期相对较晚。树木年代学过程有时会产生大量漂浮的年代学碎片，并得到许多放射性碳测年的补充。在日历确定的松树年表之前和之后，还有放射性碳定年的浮动年表。这份松树记录部分可以追溯到公元前九世纪初，记录了全新世早期的环境状况。它还显示了年代学进一步延伸到过去的潜力。德国西北部松树年代学从此成为考古发现（例如新石器时代木沼泽轨道）年代测定的基础。此外，泥炭保存的松树已被证明在古环境研究中很有价值，因为它们生长在对水文变化敏感的地方。特别是与气候相关的沼泽进展在材料中得到了很好的体现。
To date, the tree-ring chronology of peat-preserved pines from Northwest Germany (Fig. 1) spans from 6703 BC to 1166 BC, but still contains two gaps. It was dated with the help of the previously constructed bog-oak chronology of Northwest Germany, the older part of which in turn has been dated using the pine chronology (Fig. 2), now covering from 6628 to 6178 BC additional to the previous span of 6069 BC to 931 AD. Compared to the oaks, chronology construction required large numbers of samples of the short-lived pine trees, many of which remained undated or dated relatively only. The dendrochronological process, which at times delivered a multitude of floating chronology fragments, was complemented by a number of radiocarbon dates. Preceding and following the calendar-dated pine chronology, there are radiocarbon dated floating chronologies. This pine record partly dates back to the beginning of the 9th millennium BC and documents environmental conditions during the early Holocene. It also shows the potential of the chronology to be extended further into the past.The Northwest German pine chronology has since been the base for dating ia archaeological finds, such as Neolithic wooden bog trackways. Moreover, the peat-preserved pines have proved to be valuable in palaeoenvironmental research, as they grew at sites where they were sensitive to hydrological changes. Particularly the climate-related advances of raised bog are well reflected in the material.
