Trees in Urban Landscapes

The collection Trees in Urban Landscapes contains information from the former Dryade data bank. This data bank, with 1000 trees, gave information on the use of trees in Dutch forests, plantations and urban landscapes, such as parks and public gardens and along roads and streets.

Dryade was made at the former Institute for Forestry and Nature Research IBN-DLO, which in 2000 became part of Alterra. Furthermore, data were derived from Dutch and international literature.

Not from all species are photos available unfortunately.

The use of the trees in urban landscapes 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.
