Caucasus Nature Reserve
Caucasus Nature Reserve (russian: Кавказский государственный природный биосферный заповедник имени Х. Г. Шапошникова) (also Caucasus, or Kavkasky) is a Russia, Russian 'zapovednik' (strict ecological reserve) covering a heavily mountainous section of the Northwest Caucasus Mountains. It is the largest and oldest in the territory of specially protected natural area in the Caucasus, having been created in 1924 as the Caucasian Bison Reserve.

Lesser Caucasus
The Lesser Caucasus, also called Caucasus Minor, is the second of the two main mountain ranges of Caucasus mountains, of length about . The western portion of the Lesser Caucasus overlaps and converges with east Turkey and northwest Iran. It runs parallel to the Greater Caucasus, at a distance averaging about south from the Likhi Range (Georgia) and limits east Turkey from the north and north-east. It is connected to the Greater Caucasus by the Likhi Range (Georgia) and separated from it by the Kolkhida Lowland (Georgia) in the west and Kura-Aras Lowland (Azerbaijan) (by the Kura River) in the east. The highest peak is Aragats, . The borders between Georgia, Turkey, Armenia, Azerbaijan and Iran run through the range, although its crest does not usually define the border.

Nordmann Fir
''Abies nordmanniana'', the Nordmann fir or Caucasian fir, is a fir Indigenous (ecology), indigenous to the mountains south and east of the Black Sea, in Turkey, Georgia (country), Georgia and the Russian Caucasus. It occurs at altitudes of 900–2,200 m on mountains with precipitation of over 1,000 mm. The current distribution of the Nordmann fir is associated with the forest refugium (population biology), refugia that existed during the Last Glacial Period, Ice Age at the eastern and southern Black Sea coast. In spite of currently suitable climate, the species is not found in areas of the Eastern Greater Caucasus, which are separated from the Black Sea Coast by more than 400–500 km.

Sweet Chestnut
''Castanea sativa'', the sweet chestnut, Spanish chestnut or just chestnut, is a species of tree in the family Fagaceae, native to Southern Europe and Asia Minor, and widely cultivated throughout the temperate world.

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...
