Climate and Plant Cover. The climate varies depending on the regions. Because the Caucasus Mountains obstruct the cold northern winds and the country is affected by the humid and warm weather stream coming from the Black Sea, the weather of the country is warm and rainy in general. Subtropical characteristics are seen in the Kolhit plain near to the Black Sea. The precipitation generally occurs in falls and winters and its amount declines towards the east. The annual average of precipitation is 1600 – 2000 mm in Kolhit plain, while it is as low as 508 mm in Kartli and Kaheti plateaus. While the difference in the temperature in the western part does not vary so much between the summer and winter, the seasonal difference is higher in the east where the land climate dominates. Subtropical plant cover exists in precipitous Kolhit plain and there is a proper environment for bamboo, eucalyptus and palm trees to cultivate. The regions close to the Black Sea are dominated by the forests consisting of hornbeam trees with 1000-2000m height and pine trees with 2000m height. There are pastures in the higher regions. As the climate becomes land-characterized towards the east, the plants happen to be more dwarfish. The one-third of the lands of the country is covered by forests with pine, spruce, oak, chestnut, beech, fir, ash and linden trees. In the high areas of the forests and mountains there are wild goats, deer, wild pigs, bears, lynx, fox and wolves. There are also plenty of trout in the rivers.
