Regional Red List is an official document protecting biodiversity at the local scale, where it is crucial to use up-to-date information on species occurrences obtained locally. Poorly populated and studied territories in Northwestern Siberia experience a deficit of such data. Biodiversity data portals for these regions are just beginning to emerge. The assessment of Red Lists in Khanty-Mansi Autonomous Okrug-Yugra for the past editions (2003, 2013) was based primarily on expert opinion. As part of the regional biodiversity data mobilization initiative, lots of data was released for fundamental and applied purposes. Mobilization of fungal records included several sources: 1) regional biological collections, 2) regional literature data, and 3) revision of citizen science observations on the iNaturalist.org platform. Approximately 60K fungal occurrences have been mobilized as a result. We used these open data to assess the status and compile annotations for protected species during the next edition of the Red List of the Yugra region (2024). From the obtained about 60K records, species already included in protected lists of various statuses were filtered out: IUCN Red List, National Red List (2023), previous edition of the regional Red List (2013), and were further revised to assess its status for the new edition. Additionally, rare indicator species were assessed and proposed in various statuses in the new edition. As a result of the revision of accumulated occurrences, a dataset was published in GBIF, including about 1.5K records of 62 species protected by the regional Red List of Khanty-Mansi Autonomous Okrug-Yugra (2024). The number of findings of individual species varied from one to several hundred. The dataset includes information on taxonomic names, coordinates, dates of the finding, source of information, conservation status, and others.
