“…According to the classification of floristic regions (Zohary 1973, Takhtajan 1986, Léonard 1988, 1993, the study area is located in the Irano-Turanian (IT) region. IT elements comprise more than 69% of the flora of the HWR.…”

“…The flora of Iran is influenced by three main floristic regions of the Old World, i.e. Irano-Turanian (IT), Euro-Siberian (ES), and Saharo-Sindian (SS) (Zohary 1973, Léonard 1988, 1993. The mountainous terrain of the NE Iran belongs to an independent floristic province of the IT region, named "Khorassan-Kopet Dagh" (Memariani et al 2016a).…”

Plant diversity of the Heydari Wildlife Refuge in northeastern Iran, with a checklist of vascular plants

et al. 2018

View full text Add to dashboard Cite

Heydari Wildlife Refuge (HWR) is located in Binalood mountain range of the Razavi Khorassan Province in Northeastern Iran. The area belongs to the central part of Khorassan-Kopet Dagh floristic province, which is a transitional zone between different phytogeographical units in the Irano-Turanian region. We investigated the floristic composition, life-form spectrum and the phytogeography of the area during 2014-2017 by collecting vascular plants and establishing 443 random-quadrats in representative stands of different vegetation types. A total of 588 vascular plant taxa (species and subspecies) belonging to 304 genera and 65 families are recorded as native and naturalized in the study area. The richest plant families are Asteraceae (40 genera/87 species), Fabaceae (15/72), Poaceae (33/60), Brassicaceae (33/49), Lamiaceae (19/32), and Apiaceae (18/27). The genera Astragalus (44 species), Cousinia (17), and Allium (10) are the richest ones. However, the dominant canopy cover belongs to Acantholimon, Astragalus, Artemisia, and Acanthophyllum species. Raunkiaer's plant life-form spectrum in the area is dominated by hemicryptophytes (41.50%) and therophytes (28.06%). The core flora of HWR has the Irano-Turanian origin; the widespread elements are also well represented in the study area. Based on the Sørensen dissimilarity index, the HWR has about 50% dissimilarity to the adjacent areas. The study area is inhabited by several Iranian and/or Khorassan-Kopet Dagh endemic (19%), threatened (16%), and narrow-range plant species. The results indicate the importance of the HWR in the plant diversity of NE Iran.

“…7300 vascular plant species (Akhani 2006) in 1.65 million square kilometer surface area and is the second richest country of plant diversity in SW Asia after Turkey (Davis et al 1994). The rich flora of Iran is the consequence of the phytogeographical position of Iran among three main floristic regions of the Old World, including Irano-Turanian, Euro-Siberian and Saharo-Sindian, and influencing by Mediterranean and Somalia-Masaei species (Zohary 1973;Léonard 1988Léonard , 1993Akhani & Deil 2012). The mountains and foothills of northeastern parts of Iran belong to Khorassan-Kopet Dagh floristic province of the Irano-Turanian region.…”

Plant diversity of Ghorkhod Protected Area, NE Iran

Ghorkhod Protected Area (GPA) is located in a transitional zone among different biogeographical units in North Khorassan Province, NE Iran. The study area is mainly a mountainous region in western extensions of Khorassan-Kopet Dagh floristic province. We investigated the floristic composition, life form spectrum and phytogeography of the study area through several random collection efforts and 200 vegetation samples (reléves) in selected vegetation types during 2007–2012. A total of 663 vascular plant species belonging to 367 genera and 81 families are recorded as native and naturalized in GPA. Angiosperms and Dicots are among the most diverse plant groups. The richest plant families are Asteraceae (88 species), Poaceae (78), Lamiaceae (45), Brassicaceae (43), Fabaceae (38), and Caryophyllaceae (32). The genera Allium L. (17 species), Astragalus L. (15) and Cousinia Cass. (12) are the richest ones, however, the majority of the species belongs to oligotypic and monotypic genera. Life form spectrum of the study area is dominated by hemicryptophytes (38.9%) and therophytes (23.4%). Allium transvestiens Vved., Agropyron desertorum Schult., Helictotrichon turcomanicum Czopanov and Piptatherum latifolium (Roshev.) Nevski are recorded as new to Iran. The core flora of the area has the Irano-Turanian origin. However, the wide-range and widespread elements are also well represented in the study area. GPA is inhabited by several endemic, rare and narrow-range plant species, indicating the biodiversity importance of the study area in NE Iran.

“…However, unlike the more north-central Iranian deserts, less than half of the species found in the periphery of this desert belong to the Irano-Turanian endemic species and there is a considerable percentage of plants belonging to other regions. This makes Léonard to define the Lut as a "Local zone of endemic impoverishment" within the "Irano-Turanian regional zone of endemism" (Léonard, 1993). Indeed, 35.6% of the Lut elements belong to the Irano Turanian region while 16.8% to the Saharo-Sindian region, 7.6% to Nubo-Sindian, 4.2% to Somalia-Massai, 0.7% to Indian regions and the rest of the elements are the linking species simultaneously found in several regions.…”

We present the entomological results of a geological and biological exploration in the Lutdesert, performed in 2014 by the Iranian National Institute for Oceanography and AtmosphericSciences (INIOAS) and the University of Tehran. Five localities were sampled, including theone considered as the the hottest spot on Earth. They yielded 15 insect taxa belonging to Blat-todea, Orthoptera, Coleoptera, Heteroptera, suggesting that in spite of being originally de-scribed as “abiotic” or “aphytic”, the Lut desert shelters a diverse insect fauna with someremarkable elements such as the endemic desert cockroache Leiopteroblatta monodi. Compar-ison with results obtained by Franco-Iranian expeditions in the sixties and seventies revealsseveral taxa in common, but also striking differences in the composition of the insect assem-blages, suggesting that the insect fauna in the Lut desert is potentially much more diverse thanpreviously expected.
