СОВРЕМЕННОЕ СОСТОЯНИЕ АРЕАЛА И ЭКОЛОГИЧЕСКИЕ ОСОБЕННОСТИ РЕДКОГО ВИДА ORNITHOGALUM FISCHERIANUM KRASCH. НА ТЕРРИТОРИИ КАЗАХСТАНА

This paper presents a generalized analysis of the distribution and ecological features of Ornithogalum fischerianum Krasch. in Kazakhstan, based on the data from scientific literature and the Global Biodiversity Information Facility (GBIF). The species is an important component of the steppe and semi-desert ecosystems of Eurasia, but information on its range in Kazakhstan has so far remained fragmentary. Based on the available data, the Extent of Occurrence (821.100 km²) and Area of ​​Occupancy (84 km²) were calculated, demonstrating a high degree of range fragmentation and indicating the need for additional field studies. It is shown that O. fischerianum has high ecological plasticity, occurring both in natural habitats (forb-grass, feather-grass-fescue, wormwood-grass, solonetz and calciphyte communities) and in anthropogenically transformed landscapes, including urban flora. However, the identified populations are usually local and small in number, which indicates the potential vulnerability of the species. The need to review the conservation status of O. fischerianum at the international level is noted, since it is not represented in the IUCN Red List, despite being included in the national Red Books of Kazakhstan, Russia and Ukraine. The importance of further studying the dynamics of populations, threat factors and justification of conservation measures is emphasized, which is important for the conservation of the biodiversity of the steppe ecosystems of Kazakhstan.
