These two adjacent reserves (Tandoureh National Park and Protected Area), 40 km north-north-east of Quchan, incorporate a section of the Kopet Dagh Mountains with a spectacular central valley flanked by impressive cliffs and containing a large perennial spring (Chehelmere). Most of the area consists of montane steppe with Juniperus woodland on steep slopes and some riverine thickets in the valleys. Principal habitats include Artemisia steppe and open scrub with scattered Juniperus in the central valley (930-1,500 m), steep rocky hillside with good montane steppe and stunted Juniperus (1,200-2,000 m), summit ridges and plateaus with well-watered montane steppe and some rocky outcrops (2,000-2,612 m), and spectacular cliffs, crags and gorges. There is a dense stand of riparian woodland in the gorge below Chehelmere spring.
