Assessing the potential of the cultural ecosystem services of green areas (values, images and behaviors that green areas offer to their visitors) is one of the tasks of the systemic development of natural ecosystems in the city. The article shows how data from geolocated social media, namely Instagram supplemented with Google Places and Strava, is used to analyze the representation of green areas in the perception of users as well as their actual use practices. In the study of Voronezh 33 topical green zones represented in Instagram posts are defined and the categories of public value of the green zones are constructed based on the hashtags. Three varying cases of urban green are analyzed in detail and compared to demonstrate the ability of the VGI to reveal differences in their public value. It is shown how different VGI sources supplement each other and give a more nuanced picture of the public value profile of the park.
