reasonably good source of information about the temporal changes and transitions that
have taken place in recent decades. Their value in this context derives from the
comparatively long time-series of data that they provide (c.f. the multispectral images
produced by digital remote sensing devices). GIS is an ideal tool with which to
examine both the amount and the rate of transition of habitats, as well as to demarcate
the areas that need urgent attention in terms of management and conservation. In
combining these technologies, this study has helped to highlight those areas and
habitats that could be rehabilitated under appropriate management programmes and,
ultimately, to ensure that the biodiversity of this coastal dune system is maintained.
