A new association of Satureja montana L. subsp. montana dominated garrigues in Puglia (SE Italy)

Abstract

In this paper a survey on the garrigue vegetation dominated by Satureja montana subsp. montana occurring in the Alta Murgia National Park is presented. These communities were compared with those of the Ionian Arc ravines. Syntaxonomic, structural, chorological and ecological analyses were performed in order to achieve a proper classification of this vegetation. A new association is here described, the Rhamno saxatilis-Saturejetum montanae, with two new subassociations, typicum and fumanetosum procumbentis. It is a garrigue vegetation dominated by Satureja montana subsp. montana occurring in the Murgian area, in sites characterized by rocky and stony soils and by a Mediterranean Pluviseasonal oceanic weak semicontinental phytoclimate, with thermotype upper meso-Mediterranean and ombrotype lower subhumid, and is here framed in the Cytiso spinescentis-Saturejion montanae alliance (order Cisto cretici-Ericetalia manipuliflorae, class Cisto cretici-Micromerietea julianae). The results contribute to add a further piece to the knowledge of the natural plant landscape of the territory of the Alta Murgia National Park.
