Over the entire observation history (up to and including 2023), the great crested newt Triturus cristatus (Laurenti, 1768) was found in 39 localities within 12 out of 23 administrative districts of the Tula region, with 23 locations (59%) discovered in the last 4 years (2020–2023). The vast majority of the find points (92.3%) belong to the zones of coniferous-broadleaved and broadleaved forests. The species is less common in the forest-steppe zone, although in general its distribution here is insufficiently studied.
