Botanical macroremains form archaeological excavations belong to the most important sources for the reconstruction of past living conditions and environmental settings. Like other archaeological finds (a.o. ceramic, bones, (non-ferrous) metals, textiles) they are part of the legacy of past societies attesting their development. Nevertheless, this type of finds is registered only in rare cases and in an unsystematic way whereby it gets irrecoverably lost for advanced and modern analyses. Therefore, systematic sampling, random analysing and subsequent archiving of the remains shall be established in cooperation with the archaeological heritage agencies of the coastal federal states to make this source better accessible for the archaeobotanical research. This is enabled by funds of the Lower Saxony Ministry of Science and Culture during the coming five years allowing to provide technical staff and flotation facilities.
