Base buildings and field huts are important habitats, especially for introduced species (Figure 1.13). These are, for example, flies such as Fucellia tergina and those belonging to the family Carnidae, and spiders such as Tegenaria domestica, Steatoda grossa and S. triangulosa.

The lands in the immediate vicinity of the bases host more introduced species than the more distant lands. The bases, which concentrate human activity and receive most newcomers, are the main introduction points of non-native species that need to acclimatize there before spreading.

All greenhouses were decommissioned in 2009 following the establishment of a national nature reserve but, in the past, these have probably played an important role in the acclimation phase of some introduced species. This was without doubt the case for aphids which, today, are among the most invasive species.
