Site description
The coppiced woodland has a canopy with a mean height of 7 meters and a stem density of 4070 stems ha-1. The woodland is dominated by Arbutus unedo L. (65%), with a relatively smaller presence of other species: Erica arborea L. (13%), Fraxinus ornus L. (8%), Quercus pubescens Willd. (5%), and Quercus cerris L. (4%). The climate at the site is typical of Mediterranean regions, with a long term (1979-2009) mean annual precipitation of 730 mm, irregularly distributed through the year, and a mean annual air temperature of 16 °C.
