Abstract
Genetisk variasjon for evolusjon og skogens evne til å tilpasse seg klimaendringer bevares best in situ i naturlige bestand. Norges nettverk av bevaringsområder er per i dag svært begrenset. Rapporten foreslår en utvidelse av nettverket basert på klimagradienter og genetiske studier for å oppfylle nasjonale og internasjonale forpliktelser.
Abstract
Key implications for ash regeneration Natural regeneration of ash is still extensive in Fjugstad. Transition into the tree layer is a critical bottleneck under high disease pressure. Local moisture, light environment, growth rate and infection pressure may influence seedling performance. Dense shrub-layer ash with apparently healthy individuals may be useful targets for monitoring and conservation-oriented management. Continued spatial monitoring can identify microsites and individual trees with potential for future ash persistence. Integrate GNSS-based spatial data with moisture and light variables and follow effects of windthrow and canopy opening on new ash regeneration.

Abstract Key message This dataset reports translocation experiments on 15,774 seeds from 43 populations of Abies alba Mill., Acer pseudoplatanus L., Fagus sylvatica L., Quercus petraea (Matt.) Liebl., Quercus pubescens Willd., and Quercus suber L. It informs ecological and evolutionary processes in early tree stages.
