The natural characteristics of protected areas have changed for a variety of reasons through time. Changes in protected area landscapes can occur because of natural and/or cultural processes. Natural processes such as geomorphologic disturbance and climatic condition can permanently and/or temporarily change the characteristics of the environment. In addition, changes in human needs, knowledge and activities are the cultural driving forces behind changing characteristics of landscape through time. Herein, the contact between citizens and open spaces continues to block the successful movement of open and especially urban spaces. One of the most important parts of this relationship is local citizens’ awareness of open spaces.
