Future ash trees - screening and selection of common ash for resistance to ash dieback
Ash dieback spreads across Europe and causes leaf loss, crown dieback and bark lesions in affected ash trees (Fraxinus excelsior). Once a tree is infected the disease is usually fatal. Results from Denmark indicate that ca 1% of a ...

Comparing the ecology across European tree species
Project description: Foresters modify the structure and light environment of forests to manage the future development of the forest. Natural regeneration and competition between different species are important in current forest ma ...

Tapering of vessels in oak – a key feature to explain the dying-off?
There is a clear gradient in vessel size when following the same tree ring along a tree with vessel size increasing from the top of the tree towards the stem base. This phenomenon, known as tapering, is related to the hydraulic ar ...

Habitat trees as biodiversity hotspots
The main part of the Dutch forests has been developed from the afforestations of former heathlands and driftsands in the past century. The trees are relatively young, often planted in monocultures and forest remain species-poor. I ...

Growth responses to thinning in douglas fir
Douglas fir (Pseudotsuga menziesii) is one of the most productive tree species in European forests. Douglas fir stands are maintained by thinning until a point where regeneration is started and the old trees removed. Conventional  ...

Individual increment functions for douglas fir
Kroondomein Het Loo (a large forest estate near Apeldoorn) and the FEM group recently established two marteloscopes in douglas fir stands. Marteloscopes are forests especially designed for doing exercises in forest management. All ...

Anatomical traits regulate cavitation resistance in conifer tree species
Conifers (co-)dominate in many forests in different climates across the temperate zone, with some species better adapted to cold or dry habitats than others. Their wood anatomical traits (i.e., extremely narrow tracheid size and  ...

How do woody species differ in hydraulic architecture?
Hydraulic architecture refers to form characteristics of plants that characterize the water relationships. The Huber value, named after a German researcher active in the 20/30-ties of the 20th century, is the ratio between the sap ...

Forest dynamics in oak- beech forest
The Netherlands contain a significant proportion of Atlantic beech forest ecosystems. On the Veluwe, a number of old forest complexes contain well-developed forest ecosystems of this type in late-successional communities. The comm ...

Are Prunus serotina dominated forests less diverse?
Prunus serotina is regarded as an invasive exotic tree species, and much money and effort are spent on its eradication. Most forests on sandy soils contain the species, often as dominant in the shrub layer. It occurs on the black  ...
