Hankavan Hydrological

Hankavan Hydrological State Sanctuary protects approximately 4,200 hectares of mountain forest and riparian habitat in the upper reaches of the Marmarik River valley in Kotayk Province, central Armenia. The sanctuary's primary purpose is protecting the watershed that supplies water to surrounding communities, with the well-preserved forest cover maintaining water quality and regulating seasonal flow. The area combines hydrological protection with significant biodiversity conservation value.

The mountain forests support populations of brown bears, wolves, wild boar, and roe deer. The clean mountain streams support brown trout and Caucasian barbel. Forest birds include various woodpeckers, Caucasian black grouse in subalpine areas, and raptors including golden eagles. Otters inhabit the river system. The forest-meadow ecotone supports diverse butterfly and insect communities.

Mixed deciduous forest of beech, hornbeam, and oak covers the mountain slopes, with riparian vegetation of alder and willow along the Marmarik River. Subalpine meadows above the treeline support diverse wildflower communities. The forests are well-structured with multiple canopy layers and abundant understory vegetation. Various medicinal plants traditionally harvested by local communities grow in the forest clearings.

The sanctuary occupies the upper Marmarik River catchment in the Pambak Range, composed of volcanic and metamorphic rocks. The terrain is mountainous with elevations from 1,800 to 2,800 meters. Numerous springs emerge from the fractured rock, feeding the river system. The geological structure creates aquifer systems that the forest cover protects from contamination.

The mountain climate features cold winters with significant snowfall and cool, moist summers. Annual precipitation reaches 700 to 900 millimeters, providing abundant water for the forest and river system. The snowpack serves as a natural reservoir, releasing water gradually through the spring melt season. Average temperatures range from minus 6 degrees in January to 15 degrees in July.

The mountain valley has been used for summer grazing and limited timber harvesting by Armenian communities for centuries. The resort town of Hankavan below the sanctuary was developed during the Soviet period. The forests were exploited for fuel during the energy crisis but their hydrological function was recognized as essential for downstream water supply.

The sanctuary was established with the dual purpose of watershed protection and biodiversity conservation. The critical importance of maintaining forest cover for water supply regulation drove the designation. Management aims to prevent any activities that could compromise water quality or forest integrity.

Mountain hiking trails follow the Marmarik River valley through forested slopes to alpine meadows with panoramic views. The clean mountain river provides scenic interest throughout the walk. The resort town of Hankavan serves as a gateway. Summer wildflower meadows and autumn forest colors are seasonal highlights.

The sanctuary is accessible from the resort town of Hankavan in Kotayk Province, approximately 70 kilometers north of Yerevan. Hankavan offers hotels and guesthouses. Trails into the sanctuary start from the town. No facilities exist within the sanctuary itself.

Maintaining forest cover for watershed protection is the primary management priority. Illegal logging threatens both biodiversity and water quality. Overgrazing prevents forest regeneration in some areas. Climate change may affect precipitation patterns and forest health. The direct link between forest conservation and water supply for downstream communities provides strong socioeconomic justification for protection.
