The expression russet-red ant indicates one or of the species (S) of Fourmis, boreal, of the group Formica rufa present in the forests of coniferous tree or leafy trees, and groups it him even which includes/understands in France 6 or 7 species of Fourmi S of wood (but they are not the only ones with living in forest). The upper part of their Fourmilière S are domes of brushwood being able to reach 1,50 m height, often located in edge of wooded pieces or in small clearings. The russet-red ants are protected in France and in several countries because of their utility for protection of the trees against many insects which can harm to them if they are not controlled by the predatory ones such as the russet-red ant. Anthills were successfully reintroduced in wooded pieces from where they had disappeared.
Threats
All the ants of wood are threatened mainly by the artificialisation, the destruction and the fragmentation of the forests, the lack of deadwood, and sometimes by the voluntary destruction of their nests by actors who are unaware of their ecological utility. The forest fires repeated concerning large surfaces can also affect their populations.Only for France, were already regarded as threatened in 1996, according to the Base of data of the World Conservation Monitoring Centers (WCMC), the following species:
- Ant of wood European reds ( Formica aquilonia )/European Red Wood Ant
- European Ant of wood reds ( Formica lugubris )/European Red Wood Ant
- European Ant of wood reds ( Formica polyctena )/European Red Wood Ant
- European Ant of wood reds ( Formica pratensis/nigricans )/European Red Wood Ant
- russet-red Ant ( Formica rufa )/European Red Wood Ant
- European Ant of wood reds ( Formica uralensis )/European Red Wood Ant
They since are regarded as threatened by the international red list of UICN.
