Zarrei, M., Wilkin, P., Ingrouille, M.J. & Chase, M.W. 2010. Gagea robusta (Liliaceae), a new species from Flora Iranica area. Kew Bulletin 65: 327. DOI: https://doi.org/10.1007/s12225-010-9196-1

Conservation
The extent of occurrence (EOO) of this species was estimated to be 25000 km2 based on Fig. 2A. Twelve localities support Gagearobusta based on the herbarium specimens collected to date. However, fieldwork suggests populations are small, comprising only a few individuals with an estimate of between 1000 and 10,000 individuals appearing likely. These data suggest a possible conservative provisional IUCN Red List category of near threatened (NT) (IUCN 2001). Although some known populations such as Zarrei & Zarre 1032 and Akhani 10229, are in protected areas, most populations are under grazing pressure. Further research on the conservation status of this species is needed, in particular to discover the degree of threat posed by grazing.
Distribution
This species occurs from northern and northeastern Iran to western and central Afghanistan
Ecology
This new species is widely distributed in Iran, but it is scattered (Fig. 2A). Two localities were also recorded from Afghansitan (Fig. 2A) based on herbarium specimens. One was collected from around Bamian (Hedge & Wendelbo W4613) and the second one collected from Ghowr (Köie 4274). It has been mostly observed in open habitats with no shrubs or trees. However, Furse 7187 was collected from woodland with scarce Juniperusexcelsa Wall. trees. Zarrei 1172 was collected from foothills with some shrubs of Berberis integerrima Bunge and rarely Juniperus excelsa trees. The following species have been observed in the locality of Zarrei 1172: Gagea kunawurensis (Royle) Greuter (an accepted name for G. stipitata Merckl. ex Bunge according to Zarrei et al.2010c), G. reticulata, G. iranica Zarrei & Zarre, G. vegeta Vved., Fritillaria raddeana Regel, Artemisia sieberi Bess., Tulipa montana Lindl. var. montana, Hyacinthus litwinovii Czerniak., Poa bulbosa L., Muscari neglectum Guss. ex Ten., Juniperus excelsa, and Berberis integerrima. Artemisia steppe is the preferred habitat of this newly discovered species (Fig. 3A). Soils with a high percentage of clay covered by Poa bulbosa are mostly preferred. However, it has been observed on steep scree-covered slopes.
