Abstract
A review of the status of Taxus baccata L. forests in Sardegna (Italy) is given. 6 new sites have been discovered (to add to the 41 formerly known sites). The species have a large range of altitudes -50-1550 m-, but it uses to live from the upper Meso-Mediterranean (MM) to the medium Supra-Mediterranean (SM) thermotype, preferablely under humide (H) or upper-subhumide (SH) ombrotype. As a result of this work two plant associations have been proposed: 1) Phillyreo latifoliae-Taxetum baccatae nom. prov., for acid substrata, having its best sites by 500-900 m, thermotype MM, ombrotype upper-SH to lower-H, and being enclosed in Fraxino orni-Quercion ilicis (Quercetalia ilicis, Quercetea ilicis); and 2) Glechomo sardoae-Taxetum baccatae nom. prov., on basic substrata, 900-1500 m, optimum SM lower-H, syntaxonomically included in Pino calabricae-Quercion congestae (Quercetalia pubescente-petraeae, Querco roboris-Fagetea sylvaticae).
