The natural temperate broadleaved forests of Southern Sweden have almost completely been transformed into conifer forests and farmlands, leading to loss of some important woodland key habitats and biodiversity. Reintroducing temperate broadleaved species, especially oaks (Quercus robur and Quercus petraea), is important in order to restore and strengthen such forest types. A successful establishment of young oak seedlings is therefore critical. Interspecific competition from natural vegetation is considered to be an important element
during structural changes in plant communities, and may therefore be a major factor during the establishment of young oak seedlings. Competition from herbaceous vegetation has been observed to reduce the establishment success of
young oaks, whereas interference from shrub vegetation does not have to be negative for the oak seedling.
My research aims to assess the relative importance of facilitation and competition from shrub vegetation, during the establishment period in young oak seedlings.

Practical experience and understanding of the interspecific competition and facilitation situation for oak seedlings grown in shrubs may be important when developing nature-based and cost-efficient regeneration methods, to ensure a successful
conservation and restoration of Southern Sweden’s broadleaved woodlands.
