1. For each species we present the most cited common name although there are others in the studied area.
2. The presence of some of these species is really affected by abandonment and changing in cover and agricultural practices. Nevertheless, according to our informants, those still occurring and existing, have different food and medicinal properties which may have impact in quality and safety. LK is needed to an integrated and sustainable management of habitats and plant materials.
