This study extracts 80,500 Flickr photographs from non-urban areas of the Tahoe Central Sierra Initiative project (2005–2019) and treats them as a proxy for recreational visits. Automated image content analysis identifies recreation-linked concepts, while a Random Forest model quantifies environmental drivers and predicts recreation potential across the region. Results indicate major drivers including vegetation cover, land cover, elevation, smoke days, and landscape features, and they estimate that 25.9% of the area supports recreation potential, mostly within protected areas.","UC Irvine  \nUC Irvine Previously Published Works  \nTitle  \nUsing social media data and machine learning to map recreational ecosystem services  \nPermalink  \n[https://escholarship.org/uc/item/8ps5m7cs](https://escholarship.org/uc/item/8ps5m7cs)  \nAuthors  \nNyelele, Charity  \nKeske, Catherine Chung, Min Gonet al.  \nPublication Date  \n2023-10-01  \nDOI  \n10.1016/j.ecolind.2023.110606  \nCopyright Information  \nThis work is made available under the terms of a Creative Commons AttributionNonCommercial-NoDerivatives License, availalbe at [https://creativecommons.org/licenses/by-nc-nd/4.0/](https://creativecommons.org/licenses/by-nc-nd/4.0/)  \nPeer reviewed  \n[eScholarship.org](eScholarship.org) Powered by the California Digital Library  \nUniversity of California  \nEcological Indicators 154 (2023) 110606  \nContents lists available at ScienceDirect  \nEcological Indicators  \njournal [homepage: www.elsevier.com/locate/ecolind](homepage: www.elsevier.com/locate/ecolind)  \n| Using social media data and machine learning to map recreational ecosystem services\u003Cbr>Charity Nyelelea, b, *, Catherine Keskec, Min Gon Chung c, Han Guod, Benis N.

Here, we use recreation to show how social media data, machine learning, and spatial analysis techniques can improve our understanding of human-nature interactions and the mapping of recreational ecosystem services. We extracted 80,500 photographs taken in non-urban areas of the Tahoe Central Sierra Initiative project area in California between 2005 and 2019 that were posted to the photo sharing application Flickr and used these as a proxy for recreational visits to the area. Automated image content analysis was used to identify the objects and concepts in the photographs and uncover the types of nature experiences that are important to visitors. Additionally, variable importance, a Random Forest machine learning technique, was used to examine the environmental and landscape variables that drive recreation in the area and to create a classification model that predicts the recreation potential of the entire area based on important variables. The automated image content analysis identified 1,239 unique labels linked to recreation, with mountains, hills, and rocks being the most prominent features (22%). Our Random Forest model indicates that vegetation cover, land cover, elevation, smoke days, and landscape features are major drivers of recreation in the area and are of interest to visitors in the area. The model predicted that 25.9% of the area has the potential to support recreational visits. Most of these recreation potential areas are in protected areas (77.8%), predominantly in conifer forests (66%) and within national forest boundaries, especially the Tahoe National Forest area (37.6%). These results show that recreational ecosystem services vary across landscapes and illustrate the need for improved mapping approaches to determine the provision of ecosystem services in different places. The analysis provides novel insights into the various ways social media data and machine learning techniques can be powerful components of ecosystem service research and how they hold great potential
