The main limiting factors for living of Ambrosia artemisiifolia L. in the Caucasus are the incoming solar energy flux in January (5250–5950 kJ m–² day–¹) and slope (0°–17.5°). The limiting factors for A. trifida L. are wind speed in February (2–2.4 m/s) and the incoming solar energy flux in December (4400–4800 kJ m–² day–¹). In accordance with the predicted trends of climate change by 2050, it is possible to expect the expansion of the total area of potentially suitable for the species habitats by a factor of 1.95 (A. artemisiifolia) and 9.78 (A. trifida) (20 295.29 and 34817.82 km²). The area of optimal habitats may increase by 2.48 and 11.78 times, respectively (9932.73 and 18 914.11 km²), including the mountainous territoties.
