The Breite Ancient Oaks Tree Reserve near to Sighişoara (Schäßburg, Romania) is probably one of the best preserved wood-pastures in Central-East Europe. Although it is renowned mostly for its veteran oaks, the herbaceous vegetation is also of conservation interest, increasing the biodiversity of the site. The paper aims to describe the current grou...

Introduction Wood-pastures developed in many areas of Europe as a shared community resource under the governance of local institutions (for example Vera, 2000; Chételat et al., 2013; see also Bieling and Konold, this volume). While such communal governance systems have largely disappeared in northern and western Europe, they remain widespread in Ro...
