The paper describes plant species characteristic for ash (Fraxinus exelsior L.) forests in Denmark, and compares the vegetation to beech (Fagus ssp.) forests, the dominating tree species in Danish forests, which have notably simpler ground vegetation. The writer concludes that ground vegetation can be divided into distinct types. Beech grows in several types of soil differing in their fertility (bonitet). The writer has divided the different soil types by their flora (tilstandstyper). The flora is influenced by three factors: climate, fertility of the soil and soil moisture. The paper defines the types of vegetation which describe fertility of the sites (bonitet), and discusses how age, silvicultural condition and tree species affect the vegetation.
