“…There were several articles related to cultural valuations of landscape, including sacred sites in Morocco (Jäckle et al, 2013), meanings and symbolism of Persian gardens (Farahani et al, 2016), preferences of European mountain regions (Bacher et al, 2016), or about the traditional Umbrian landscape in Italy (Torquati et al, 2017). In addition, Zurlini et al (2015) published a theoretical reflection on sustainable landscape development and value rigidity, demanding to reappraise values like in the case of 'the Pirsig's monkey trap'. However, comparatively few articles were published that had a rather direct natural scientific perspective, e.g., about the variability of vegetation due to climate change (Kullman, 2015), invasive pests (Schimmenti et al, 2017), aquatic Macrophytes (Brummer et al, 2017), and ecological assessments of biodiversity (Räsänen et al, 2015;Veselaj and Mustafa, 2015).…”
