-The fires did not result in ant-free terrains.
-At first most ant species survive the fire.
-A fire in late spring has more serious consequences than a fire in April or September.
-By the lack of food, most ant populations decreased the first years after the fire and certain ant species disappeared.
-The dune grassland vegetation’s recovered rather quickly. Most ant species are decreased or are extinct.
-The regeneration of the heathland starts slowly. Most ant species are decreased or are extinct.
-In the pine wood, the habitat is changed: all trees are dead, new vegetation is developing. Here is space for new colonisators, like Lasius psammophilus and Tetramorium caespitum.
-Lasius psammophilus takes advantage of the decline of other ant species and the transformation in new dune habitats.
-Directly after the fire the mounds of mound building ants like Formica rufa/polyctena and F. exsecta were heavily damaged, but seldom extinct, except if the fire occurs in late spring. Due to the food storage at least 47 % of the wood ants Formica rufa/polyctena moved their mounds more than ten meters. After two and a half year 60 % of the mounds survived.
- The extinction of Lasius meridionalis mounds is still a not solved issue.
