TheEast Afghan montane conifer forestsecoregion (WWF ID: PA0506) covers a series of unconnectedconifer forests alongthe border betweenAfghanistan andPakistan, at elevations of 2,000 metres (6,600 ft) to 3,400 metres (11,200 ft) above sea level. The ecoregion supports the near-threatened Markhor(Capra falconeri chiltanensis), known as the Screw-horned goat, the national animal of Pakistan. The forests of the ecoregion have been heavilythinned for timber.[2][3][1][4]

Location and description

[edit]

The northernmost sector is the smallest, lying on the southern edge of theHindu Kush mountains, inNuristan Province about 60 km north ofJalalabad. This subregion is bounded on the north and south by theHindu Kush alpine meadow ecoregion, and on the west and east by the drierBaluchistan xeric woodlands.[3] The middle sector is centered inPaktia Province, south ofKabul. It covers the mountains east of theGardez valley. The southern sector of the ecological range is in the mountains aboveQuetta andKuchlak in Pakistan.[3]

The soil in the northern area is gravel and organic matter over a clay substrate. In the south, the bedrock is limestone.[2]

Climate

[edit]

The climate of the ecoregion isHumid continental climate, warm summer (Köppen climate classification(Dfb)). This climate is characterized by large seasonal temperature differentials and a warm summer (at least four months averaging over 10 °C (50 °F), but no month averaging over 22 °C (72 °F).[5][6] Average precipitation in the ecoregion is 200-400 mm/year.[2]

Flora and fauna

[edit]

Only about 40% of the ecoregion is covered in vegetation, generally shrubs, herbaceous cover, and open forest. The forest type is mostly determined by altitude zones. From 2,100-2,500 meters elevation the forest is drier, with Chilgoza pine(Pinus gerardiana), holly oak(Quercus baloot), species of the beech family(Fagaceae), and cedar(Cedrus). Understory at this stage featuresIndigofera gerardiana (a legume) and Danewort(Sambucus ebulus).

From 2,500-3,100 meters, the rains from the monsoon are picked up and more deciduous trees are found among the conifers. This forest may become dense, and includes Morinda spruce(Picea smithiana), Bhutan pine(Pinus wallichiana),Quercus semecarpifolia, and Himalayan cedar(Cedrus deodara). Above 3,100 meters the forest transitions to more juniper (Juniperus seravschanica).[4]

The lakes of the northern sectors support a wide variety of migratory and breeding birds, including various species of rails (pochards, coots),marsh hens,black-necked grebe, and others.[4]

Protected areas

[edit]

About 9% of the ecoregion is officially protected. These protected areas include:[1]

The park in Nuristan Province, the northernmost sector of the ecoregion, was declared a National Park of Afghanistan in July 2020. At the time, plans for facilities and support for tourism had not yet been announced.[7]
