to check
the eco-region covers the large semi-desert region of southern afghanistan including the registan Desert and the Siestan Basin. it combines all of Freitag’s (1971, 1972) semi-desert communities in the south-western part of the country. this includes the Haloxylon salicrnicum Semi-de-sert, calliginum-artistida Semi-Desert, chenopodiumrich and amygdalus Semi-Desert communities. Dasht-e-nawar Flamingo and waterfowl Sanctuary is not legally protected by the afghan government and the insecurity that charac-terizes the area limits the realization of practical conserva-tion measures
Indus Valley desert
BALUCHISTAN XERIC WOODLANDS
67% of the territory is bare or sparse vegetation. %9 is shrubland, 8% is herbaceous vegetation, and 9% is cultivated cropland.
Below 1,500 meters, the vegetation is steppe in character. From 1,500 to 2,000 meters is found montane open forest of Pistachio trees (Pistacia atlantica), Wild almond (of genus Prunus), and Barberry (Berberis). Lower brush includes Honeysuckle bush (of genus Lonicera), Sage (Artemisia (genus) spp.), and Pashtun juniper (Juniperus macropoda). At higher altitudes there is a transition zone of Sclerophyll trees (woody brush with hard leaves). At still higher elevations are the isolated alpine meadows of other ecoregions.

THAR DESERT
OTHER PLANTS
Suaeda fruticosa
FLOWERS / HERBS
Bekario/ Heartleaf indigo
The Thar’s desert sands overlie Archean (early Precambrian) gneiss (metamorphic rocks formed between 4 billion and 2.5 billion years ago), Proterozoic (later Precambrian) sedimentary rocks (formed about 2.5 billion to 541 million years ago), and more-recent alluvium (material deposited by rivers). The surface consists of aeolian (wind-deposited) sand that has accumulated over the past 1.8 million years.
The soils consist of several main groups—desert soils, red desertic soils, sierozems (brownish gray soils), the red and yellow soils of the foothills, the saline soils of the depressions, and the lithosols (shallow weathered soils) and regosols (soft loose soils) found in the hills. All those soils are predominantly coarse-textured, well-drained, and calcareous (calcium-bearing). A thick accumulation of lime often occurs at varying depths. The soils are generally infertile and, because of severe wind erosion, are overblown with sand.

TERRAINS
The principal topographical features of the Sahara include shallow, seasonally inundated basins (chotts and dayas) and large oasis depressions; extensive gravel-covered plains (serirs or regs); rock-strewn plateaus (hammadas); abrupt mountains; and sand sheets, dunes, and sand seas (ergs).

Sebkha, chott | Salt lake
Sebkha: floodable depression whose bottom is covered with a salt crust where no vegetation grows.
Chott: edge of the sebkha, covered with vegetation of salt tolerant plants.
Sebkhas and chotts are found south of the Tafilalet, in the flood bed of the Ziz wadi. Where the water only passes and deposits silt, we have maader; but where water accumulates, stagnates and then evaporates and deposits dissolved mineral salts, there are sebkhas and chotts.
Chaaba | Takat | Ravine
n mountainous areas, ravines collect runoff water during brief and violent floods. The bed of the wadi is most often made up of large boulders and devoid of vegetation. Trees and bushes preferentially grow at the limit between the bed of the wadi and the foot of the scree. The slopes of the ravines - like the krebs - offer a wide variety of exposures and micro-environments favorable to a sparse but varied flora.
Daya | Doline
Dayet, pl. daya: circular basin that collects rainwater on the regs or on the hamadas, when the slope is too low for drainage lines to be created.
Dayas vary greatly in size: from a few meters to a few hundred meters in diameter. After rains, their loamy soil can retain moisture for weeks to months.
