Abstract

This paper describes the slightly acidic hill forests of Quercus petraea (Matt.) Liebl. with Tilia tomentosa Mill. from the Republic of Moldova, grouped into 3 associations: Carpino orientalis-Quercetum petraeae Pînzaru, Sfecla et Cantemir, ass. nov. hoc loco, Tilio tomentosae-Quercetum petraeae Sârbu 1979 corr. Pînzaru, Sfecla et Cantemir hoc loco, Hieracio umbrosi-Quercetum petraeae Pînzaru, Cantemir, Manic & Popescu 2017 from the suballiance Tilio tomentosae-Quercion petraeae (Pînzaru & Cantemir 2023) Pînzaru, Sfecla et Cantemir, stat. nov. hoc loco. These associations occur on plateaus, in the upper part of the hills, at an altitude of 138-367 m, on yellow sands, devoid of soil, or on virgin brown or gray luvic soils, formed on sandy, loamy-clayey rocks, with the pH value ranging from 4.5 to 6.0. The phytocoenoses of the associations Carpino orientalis-Quercetum petraeae, Hieracio umbrosi-Quercetum petraeae are rare and it is proposed to include them in the future List of rare associations in the Republic of Moldova.
