The diversity and distribution of introduced plant species reflects eight thousand years of settlement history

Human population has affected natural ecosystems since prehistoric times in many ways, causing disturbances in existing ecosystems and creating novel habitats, and altering the colonisation and extinction rates with potentially long-lasting effects on biodiversity. Here, we explored the pervasive effects of past human occupancy on present-day diversity and the distribution of plant species introduced by humans in the distant past – archaeophytes – at the regional spatial scale. We analysed spatial relations between the present-day species richness of archaeophytes and native flora, the environmental setting, archaeological evidence, and the relationship between the residence time of archaeophytes and their regional range size. We used fine-scaled gridded information on plant diversity and archaeological records for the period 6000 BCE to 1000 CE summarised as average occupancy probability (AOP) in Czechia, Central Europe. The proportion of archaeophytes in local flora positively correla..., This dataset contains archaeological occupancy values, plant diversity values and environmental conditions in regular grids (5x3 arc minutes) over the study area (Czech Republic). These data were compiled from plant diversity database PLADIAS (Chytrý et al., 2021; Wild et al., 2019), archaeobotanical evidence (Pokorná et al. 2018), archaeological occupancy model (Kolář et al. 2022), climatologies (Karger et al., 2017; Karger et al., 2021), soil types (Tomášek, 2003) and forest cover (UHUL, www.uhul.cz). Data were processed in R using code which is part of this dataset.
