On the 1st of February 2006 the ‘Seeds and Plant Materials Act 2005’ has entered into force. From this date the Board for Plant Varieties is the Official Body that is responsible for the registration of forest stands and varieties. The Board for Plant Varieties maintains the ‘Rassenlijst Bomen’ (List of recommended varieties and provenances of trees). This 10th Rassenlijst Bomen includes the National Register of approved Basic material of species subject to the EU Directive 1999/105/EC, which controls the marketing of Forest Reproductive Material in the EU and the recommended list of varieties and provenances of the so-called ‘non-EU species’.

The main objective of this list is to inform users (and nurserymen, and seed merchants) about the characteristics of the different varieties and provenances that can be recommended. Varieties and provenances that do not meet the requirements of the Directive are not listed.
Varieties and provenances of these species are listed only if approved in the categories ‘Source identified’, ‘Selected’, ‘Qualified’ or ‘Tested’.

Autochthonous provenances of trees and shrubs for ecological purposes are listed in the category ‘Source identified’ unless they fulfil the requirements for approval in one of the other categories. This category is reserved for autochthonous provenances only.
The ‘Rassenlijst Bomen’ is constantly reviewed and will be updated every 3 months. See the home page for the current version of the list.
