European beech in Denmark is mostly growing in even aged monocultures, perhaps with a few trees<br />
of ash (Fraxinus excelsior) and sycamore (Acer pseudoplatanus). The species is both planted and<br />
naturally regenerated. Additionally, beech is the constituent part in the un<strong>de</strong>rstorey of oak forests. The<br />
management regime might change to natural regeneration in smaller plots combined with mixtures<br />
with other species to ease natural regeneration (Larsen 2005). Planting of beech is subsidized by the<br />
state when planted in existing conifer forest and as afforestation.<br />
In 2005 the harvest of beech was 224, 00 m3 , 60,400 m3 of which were used for logs and veneer and<br />
the remaining for fire wood (Statistics Denmark 200 ).<br />
GeNeTIc resources<br />
Beech in Denmark is largely naturally regenerated. From 2001 – 2006 the average annual seed harvest<br />
and import of seed was 13.9 tons. The annual seed harvest from approved Danish stands of Danish<br />
origin was .5 tons and the annual seed harvest from approved Danish stands of any origin 11. tons,<br />
while the annual import was 2.2 tons (Bastrup-Birk et al. 2008). Danish seed sources should be<br />
approved (Bekendtgørelse om skovfrø og planter 200 ). The total area with approved seed stands, i. e.<br />
in the category of selected resources is 485 ha. The country is consi<strong>de</strong>red as one seed zone concerning<br />
beech.<br />
The Forest and Nature Agency has recently approved a number of beech stands of known local origin<br />
around the country. These stands will serve as gene conservation stands and restrictions will be ma<strong>de</strong><br />
concerning planting of beech in surrounding stands (units) (Ditlevsen, pers. comm.).<br />
Provenance field trials have only shown small differences between Danish provenances as regards<br />
growth and stem form and actually only statistical certain differences as regards growth. Provenance<br />
field trials with European provenances have revealed larger differences as regards the percentage<br />
of trees with straight stems and timing of bud burst (e. g. Hansen et al. 2003). Especially the Swiss<br />
provenance Sihlwald has shown to be superior as regards stem straightness and two approved Danish<br />
seed stands are of this origin. The use of this species, however, should be restricted to areas less prone<br />
to late frost since the buds of this provenance (like Slovak provenances) burst early.<br />
