What drives ecosystem buildup, diversity, and stability? We assess species arrival and ecosystem changes across
16 millennia by combining regional-scale plant sedimentary ancient DNA from Fennoscandia with near-complete
DNA and trait databases. We show that postglacial arrival time varies within and between plant growth forms.
Further, arrival times were mainly predicted by adaptation to temperature, disturbance, and light. Major break
points in ecological trait diversity were seen between 13.9 and 10.8 calibrated thousand years before the present
(cal ka BP), as well as break point in functional diversity at 12.0 cal ka BP, shifting from a state of ecosystem
buildup to a state where most habitat types and biotic ecosystem components were in place. Trait and functional
diversity stabilized around 8 cal ka BP, after which both remained stable, although changes in climate took place
and species inflow continued. Our ecosystem reconstruction indicates a millennial-scale time phase of formation
to reach stable and resilient levels of diversity and functioning.
