Abstract: | Effective decision making depends upon the availability of quality information. Procedures involved in assessing dune vulnerability
and protection require monitoring of sporadic processes and information must be collected from many discipline sources. In
particular, a significant challenge to strategic management is recognition of subtle discontinuities which could undermine
the long term stability of the dune system. These changes may be irregular and/or non linear requiring managers to be aware
of existing parameters, patterns and emerging discontinuities. A range of components within the system should be measured
on a systematic, temporal and spatial basis. An environmentalchecklist is a useful management technique which systematises information, so that strategic objectives can be made operational and
achievable. Problems can be identified and solved with this methodology particularly if it is incorporated into aW problem solving model. The checklist procedure proposed in this paper has been developed and tested in field conditions for
a range of north-west and south-European dune systems. Whereas a universalchecklist applicable to all systems is utopian in aim, intra and extra-regional comparisons can be undertaken with only minor modifications
of some components. Parameters covering site and dune morphology, beach condition; surface character of the seaward 200 m
of the dunes; pressure of use and recent protection measures are the basis for calculating vulnerability and protection indices.
The balance between these indices can be determined, analysed and form the foundation for future informed management decisions. |
