Description: L'inventaire forestier de Genève a été effectué en 2004. Ses objectifs sont les suivants: Fournir les données de base et de contrôle pour la gestion pérenne des massifs boisés (par exemple la structure des classes d'âge, la répartition des essences, les volumes de bois et la production de bois, etc.)
Fournir les données de base et de contrôle pour la gestion pérenne des différentes fonctions assignées à la forêt (présence de la faune, lumière au sol, départs d'érosion, images forestières, dégâts humains, etc.)
Les surfaces inventoriées sont délimitées par le tracé du cadastre forestier. Les surfaces de moins de 2 hectares ont été éliminées automatiquement et les cordons boisés trop étroits ont été enlevés manuellement.
L'inventaire est basé sur la méthode d'échantillonnage systématique par placettes temporaires. Il s'agit d'une grille callée sur les coordonnées nationales (une placette pour deux hectares et d'un rayon allant de 9 à 13 mètres en fonction de la densité des tiges).
1597 placettes ont été inventoriées pour 3000 hectares de forêt.
Le précédent inventaire a eu lieu en 1985.
