The Zangezur Mountains comprise a mountain range that defines the border between Armenia's southern province of Syunik and Azerbaijan's Nakhichevan Autonomous Republic. The second largest tracts of forests in Armenia are located in the Zangezur Mountains where they cover more than 20% of the territory of Syunik province and reach an elevation of 2,200-2,400 m. The rest of Armenia is almost devoid of forests. They occur only as small islands on the eastern slopes of the Aragats and Tsakhkunyats ranges and on the southwestern spurs of the Gegham mountains.
