About this collection

The Dryade data bank contains data on the use of trees in Dutch forests, plantations and urban landscapes, such as parks and public gardens and along roads and streets. These data are mainly based on the accumulated outcome of 25 years of research at the former Institute for Forestry and Nature Research IBN-DLO, which in 2000 became part of Alterra. Apart from this, data were derived from Dutch and international literature.

The use of these trees is considered from several aspects:

  • Landscape architecture and the spatial design of planting plans (size and form of full grown trees etc.).
  • Cultural methods.
  • Biological characteristics influencing the ways and frequency of tree maintenance.

Included are  some 1000 tree species and cultivars, deciduous trees as well as conifers.   Of these trees the following characteristics are considered:

  • General characteristics (form, size, growth rate, propagation methods).
  • Site requirements.
  • Experience-based data on usage.
  • Form and colour of leaves in summer and autumn, leaf flushing period.
  • Flowers and flowering.
  • Seeds and fruits.
  • Pests and diseases.
