Abstract(s)
Inland sand dune systems are amongst the most threatened habitat types of Europe.
Affected by severe conditions, these habitats present distinct community compositions,
which makes them excellent for studying possible interactions among their integrating
species and the environment. We focus on understanding the distribution and cooccurrence
of the species from dune plant assemblages as a key step for the adequate
protection of these habitats. Using data from an extensive survey we identified the
shrub species that could be considered indicators of the different xerophytic scrub dune
communities in South West Portugal. Then, we modelled the responses of these species
to the environmental conditions using Ecological Niche Factor Analysis. We present
some preliminary results elucidating whether using species distribution models of
indicator species at a regional scale is a valid approach to predict the distribution of the
different types of communities inhabiting these endangered habitats.
