In 2009 an online database for Sustainably Produced Timber was launched in the Netherlands: www.houtdatabase.nl. The database contains a considerable number of promotional e.g. lesser known timber species (LKTS) with information on the properties, applications and certificates for sustainable forest management. To share part of the Dutch experiences in applying LKTS in construction and waterworks, a selection of 30 reference projects has been made available in English. Also, relevant publications in English on LKTS are linked to the database.
