EXPLORING BEAVER HABITAT IN EUROPE:
BEAVERS AS THREAT TO DIKES IN THE NETHERLANDS
Beavers have been reintroduced in many counties in Europe , including the Netherlands. The beaver population is gradually growing and with that comes the conflict with the important diking system protecting the low lying areas in Holland from flooding. In 2007 ALTERRA WAGENINGEN UR published an interesting report: Graverij van bevers in de rivierdijken in de Gelderse Poort (Beavers digging in the river dikes of de Gelderse Poort- the area of the Waal river just upstream of the Nijmegen Bridge). Alterra- rapport 1604. ISSN 1566-7197. Author: F. Niewold)
After 150 years of absence beaver were reintroduced in the Netherlands in 1988 in de Biesbosch and between 1995-2000, 54 beavers (Castor fiber) were introduced in the Gelderse Poort
- In march of 2007 the total population in the Netherlands was 315 individuals, with about 80 in the Gelderse Poort.
- In two places beaver dug holes in the river dikes as lodges: Although these holes did not endanger the structural safety of the dikes, future population expansion could create a real problem.
- In this study Freek Niewold looked at potential risk areas and possible strategies to reinforce sensitive areas at risk.
