Abstract

The plant dynamic and anthropic study of northern Algeria wetlands was lead from an approach based on retro-observation and using palynology as main tool. Thus, the multi-proxy study of five sedimentary sequences supported by 9 radiocarbon dating and exploitation of contemporary pollen referential, devoted for defining a list of pollen taxa indicators of anthropisation, allow us to reconstruct the vegetation dynamics and past plant diversity in the last centuries in areas where paleobotanical data were do not exist (except for Numidia). Paleoecological data acquired allow us to write, for the biogeographical Kabylie-Constantine-Numidia sector, a local vegetation history, past biodiversity and environmental dynamics of wetlands. All these da...
