Examples of different species-urban green area models fitted with some of our datasets. a Linear model fitted with data obtained from Marseille, France, r2 = 0.52 (Lizée et al. 2011); b Power model fitted to data from Seoul, South Korea, r2 = 0.75 (Park and Lee 2000); c Kobayashi model fitted to data from Rennes, France, r2 = 0.53 (Croci et al. 2008); and d Weibull 3 model fitted to data from Santiago de Chile, Chile, r2 = 0.43 (Urquiza and Mella 2002)
