“…This may be because cultural ecosystem services are widely considered to be inherently difficult to quantify (Daniel et al, 2012;Dickinson & Hobbs, 2017;Willcock, Camp, & Peh, 2017): while many ecosystem services relate to easily measured biophysical processes or changes (Bagstad, Semmens, Ancona, & Sherrouse, 2017;Satz et al, 2013), cultural services include intangible concepts such as aesthetic value (Daniel et al, 2012;Milcu, Hanspach, Abson, & Fischer, 2013). Furthermore, people value cultural services in different ways, and these values can change over time (Gould, Coleman, & Gluck, 2018;Plieninger et al, 2015). Therefore, despite recognition of their importance (Chan, Guerry, et al, 2012;Daniel et al, 2012), cultural ecosystem services are frequently ignored or play a minimal role in valuation exercises (Small, Munday, & Durance, 2017).…”
