“…Protected areas vary widely between and within countries and regions, and the varying characteristics include the institution date, conservation focus, effective level of protection, permanence of protection, constancy of protection, ecological scale of protection, type of management, management authority and reference legislation, to cite some of them. In addition, the effectiveness of the selection process and the resulting Natura 2000 network have often been questioned because each country made its designations largely independently, and the designation of sites has been criticised as depending too strongly on governmental politics, economic and cultural criteria, and interactions between society and the environment Fenu et al, 2017;Gruber et al, 2012;Orlikowska et al, 2016;Trochet and Schmeller, 2013).
