Abstract
The forest of Bissa is a Mediterranean ecosystem, characterized by a high floristic diversity. In order to assess the floristic diversity in this forest, 133 floristic readings were conducted in this area between 2013 and 2017. As a result, it was possible to identify 151 species, 125 genus and 54 botanical families, with a clear dominance of Asteraceae, Fabaceae and Poaceae. Biologically, this ecosystem was mainly dominated by therophytes (37%). Physiognomically, the phanerophytes were the most dominant types, whereas in term of phytogeography this forest was dominated by the Mediterranean type (50%). According to Shannon-Winner index, this area was characterized by a relatively low diversity (1.3 bit / ind), with a clear dominance of a few species. Finally this forest was relatively disturbed (42%) and under a strong anthropozoic influence.
