The article evaluates the importance of protected areas in conserving nature, focusing on the "Visherskiy" State Nature Reserve as an example. The researchers developed a methodology using various data sources to assess the conservation significance of protected areas at regional, national, and global levels. The "Visherskiy" Reserve was found to be crucial for preserving a diverse range of plant and animal species, including globally rare species. The reserve plays a significant role in maintaining the natural environment of the Urals montane tundra and taiga, making it valuable on a global scale. The study suggests further improvements in assessing natural complexes and valuable hydrological objects for future conservation efforts.
