Vegetation
Natural vegetation grossly modified by agriculture, forestry and urban development; c. 40% of land-surface is man-made, the result of reclamation from the sea. Despite the drainage of the large marsh and peat bog region (the Polders) in the west, a valuable wetland flora still remains in places. The original acid oak woodland of the higher parts of the east and south, and oak/beech woodland with birch, was cleared in the mid 19th Century. Remaining areas of floristic interest: the Wadden Sea area, dunes along the North Sea, especially along the Isle of Voorne, relict heathlands of the Veluwe and the Biesbos delta (J. Mennema, 1984, in litt., quoted in Davis, S.D. et al. (1986). Plants in Danger: What do we know? IUCN, Gland, Switzerland).
Plant Conservation Programmes
19 botanic gardens are members of the Nederlandse Vereniging
van Botanische Tuinen (NVBT, founded 1998), which focuses on cooperation between
gardens.
Dutch National Plant Collection.
Collections of some 40,000 plants distributed among 17 botanic gardens in
The Netherlands. The national collection is co-ordinated and controlled by
the Dutch Botanic Gardens Foundation (Stichting Nationale Plantencollectie,
SNP), founded in 1988. The site has links to the participating botanic gardens.
The Centre for Genetic Resources (CGN)
has a mandate from the Ministry of Agriculture, Nature and Food Quality to
conserve plant, animal and forest genetic resources and to promote their utilization.
It operates a genebanks of over 20 crop collections, containing more than
23,000 accessions, and it manages and monitors provenances, test sites and
seed repositories for more than 20 forest species. CGN also functions as the
Dutch focal point on Access and Benefit Sharing of the Convention on Biological
Diversity (see www.absfocalpoint.nl).
