Over 2,000 species of vascular plant have been recorded in Turkmenistan including 462 relic and endemic species. The greatest diversity is in the mountains of the south, with many economically important fruit-bearing trees being found there, including
persimmon,
almond,
cherry,
pomegranate and
fig. The Kopet Dag woodlands consists of
xeric, shrublike woodlands known as "
shiblyak", juniper woodlands, and riparian forest. Shiblyak woodland is dominated by
Turkmen maple (
Acer tucomanicum),
hawthorns (
Crataegus spp.) and the
Jerusalem thorn (
Paliurus spinachristi). At higher altitudes, there are fewer maples and the dominant trees are hawthorn,
Juniperus turcomanica and
Celtis caucasica. On the mountain tops, grasses and cushion plants are the main members of the plant community. In the steep sided ravines, there are
walnut trees,
Syrian ash,
Thelycrania meyeri,
Prunus divaricata,
Lonicera floribunda,
Rubus sanguinoides and
Rosa lacerans. of Karakum Desert Much of the rest of the country makes up the Central Asian Southern Desert ecoregion, which includes the Karakum Desert, the southern part of the
Kyzylkum Desert and other areas with rolling dunes, sandy plateaus and alluvial plains. This area receives practically no rain during the summer and the extreme heat means that little grows at this time of year. In the winter, some precipitation with much cooler temperatures occurs, and grasses such as
Bromus and vascular plants such as
Malcolmia,
Koelpinia and
Amberboa sprout. In March and April, ephemeral plants appear, including
fox-tail lilies,
Rheums,
tulips and
stars of Bethlehem, but by the end of May these have given way to the summer drought. Communities of
Salsola grow on the alluvial flats along with
asafoetida,
Ephedra strobilacea,
black saxaul and
white saxaul. The
sand acacia and several species of
Calligonum grow among the dunes. The coastal strip consists of sandy and clayey salt deserts recently exposed by the retreating shoreline. It has unconsolidated dunes and is sparsely vegetated with salt-loving plants. This area, with its milder climate and the mists that sometimes roll in from the Caspian Sea, is home to many of the 90 species of lichen found in the country. Another lichen-rich environment is the
takirs that form as flaking crusts on drying clayey plains. ==Fauna==
