Bat roost and hunting ground restoration work (Action A5)
The Natura 2000 site is home to five bat species of community importance. The restoration and development of the former military barracks at Mont Caume will make the site more attractive to bats during the breeding and hibernation seasons and will help to boost local population numbers. There are also plans to:
- close four underground entrances
- demolish an entrance gate that is in a state of disrepair
- remove a ladder that provides access to the fort
- redevelop the interior of certain buildings to encourage bats to roost inside.
These redeveloped areas will need to be closed to the public.
High ground restoration work (Action A7)
On the ridges of Mont Caume, natural and uncontrolled reforestation has led to the loss of open spaces, including the habitat of community importance known as the "Pseudo-steppe with grasses and annuals (Thero-Brachypodietea)".
This significant reforestation phenomenon is detrimental to several plant species that are restricted to grasslands (Hormathophylla spinosa, Genista lobelii, etc.). It is also detrimental to the Marsh Fritillary, a butterfly species protected in France, Europe and worldwide, and limits the food supply of bats and certain bird species (Ortolan Bunting, Western Orphean Warbler, etc.).
The pine forest is also colonising more rocky areas, posing a real threat to the survival of Arenaria provincialis, a plant species endemic to the site.
There are therefore plans to restore 12.5 acres of high grasslands.
