Forests and other green spaces provide various ecosystem services and have numerous scientifically recognized beneficial effects on people and the environment. However the mere presence of green spaces in an area does not necessarily produce the desired effects. The 3-30-300 rule is a novelty that combines three indicators of "greenness" of cities and has the potential to simplify the evaluation of green spaces among planners, researchers and the general public. In this master thesis, we analyzed the criteria of rule 3-30-300 using ArcGIS Pro 3.0.1. software for the Municipality of Ljubljana within the highway ring, divided into neighborhood communities. 23 % of the total area is covered by tree canopy. 63 % of built-up areas achieve accessibility within a distance of 300 m or less to green areas of 1 ha or more. 66 % of buildings in the area achieve visibility of at least 3 adult trees. There is a positive medium strong correlation between canopy cover and accessibility (Pearson's r (10) = 0,567, p < 0.050). Planning larger green spaces with more adult trees and better connections could improve Ljubljana's urban ecosystem in the future. Modeling the 3-30-300 rule is pioneering research that can help identify urban areas where more attention needs to be focused on green infrastructure planning.
