Ecosystems

The mountainous areas of the South Caucasus have

a wide variety of climate zones, ranging from cold

moderate alpine peaks to temperate, humid and arid

landscapes.

The variation in climate zones gives the

region its unique and diverse biodiversity, including

many rare and endemic species (CEPF 2003). Caucasus

region has been recognized as holding an important

reservoir of biodiversity, and is indeed considered a

globally significant ‘biodiversity hotspot’ based on the

richness of species, and level of endemism, recorded.

As part of the Caucasus-Anatolian-Hyrcanian

Temperate Forest, Armenia’s forests are recognized as

a global conservation priority under WWF’s Global

200 Ecoregions (Ulander and Ter-Zakaryn 2012).

In the Southern Caucasus, the majority of forest

ecosystems in the mountains are of great importance

for mountain communities. Georgia has the highest

Vulnerability and impact assessment

percentage of forest cover in South Caucasus at

almost 40 per cent, followed by Azerbaijan and

Armenia both having forest cover of 11.8 per cent and

11.5 per cent respectively (MoENRP 2015, AZ Stat,

MoNP 2015). In Georgia, over 60 per cent of its forests

are situated on mountain slopes at an elevation of

1,000 m.a.s.l or higher (MoENRP 2015; MoENR 2010;

Ulander and Ter-Zakaryn 2012). Forest ecosystems

protect biodiversity, store carbon, and store and

purify water. In addition, they provide benefits vital

to human livelihoods and food security, including

construction materials, fuel wood, food (mushrooms,

nuts and berries), medicinal plants, and grazing areas

for animals. The ability of trees to prevent soil erosion

and landslides is essential in the hazard-exposed

mountains. The forests, however, are under constant

pressure from deforestation. Deforestation rates were

especially high after the collapse of the Soviet Union

when energy shortages were common. Wood became

the main source of energy for heating and cooking,

and in rural areas wood is still used to reduce costly

electricity and gas bills. Illegal logging for commercial

purposes also remains a serious problem in the region

(Ulander and Ter-Zakaryn 2012).

In addition to human pressures, forest ecosystems

are vulnerable to changes in temperature and

precipitation. An assessment conducted for Georgia’s

Third National Communication to the UNFCCC

found evidence of climate change impacts on forests

in all three areas investigated – Adjara, Mestia and

Borjomi Municipality – that may reduce the critical

ecosystem services provided by them. The various

climate change-related impacts included an increase

in areas infested by pests and diseases, introduction

of new diseases (Adjara and Borjomi), increased

frequency of drought and wildfires (Borjomi), and

displacement of species due to warmer temperatures,

and prolonged vegetation period (Mestia).

Similar risks for forest ecosystems due to current

and future changes in temperature and precipitation

are underlined in Armenia’s Third National

Communication (MoNP 2015). This report also

gives a comprehensive oversight into the predicted

upward vertical shift of climatic zones and vegetation.

In general, drier ecosystems will expand in the

lower altitudes while the forest ecosystems are likely

to migrate to higher altitudes. Forest coverage is

expected to gradually decline as forestland gradually

converts to open arid forests, and further to semi-

desert and steppe ecosystems. The altered ecosystems

will not only change in structure but also in the

composition of species. The boundless and fluid
