Ce guide des végétations de la région Centre-Val de Loire se compose d'une clé illustrée des végétations jusqu'au rang de l'alliance ou de la sous-alliance qui introduit en deuxième partie, le synopsis des végétations qui dresse la liste de 525 associations et groupements élémentaires au sein d'un synsystème comprenant 148 alliances, 75 ordres et 43 classes.

Nous espérons que ce guide permettra de nommer plus aisément les végétations qui nous entourent en Centre-Val de Loire et facilitera l'accès à la phytosociologie à toute personne désireuse de progresser dans ce domaine passionnant. Nous souhaitons ainsi qu'il contribue à élargir le panel d'utilisateurs à la reconnaissance des végétations jusqu'alors réservée à trop peu de personnes.
