The present study provides an overview of geographic distribution patterns as well as the conservation priorities assessment of the genus Pseudopodospermum in Iran, using a GIS framework. A set of geographic distribution data was compiled through field studies, reviews of Flora Iranica, Flora of Iran, and examination of the herbarium specimens deposited at various herbaria. The geographic distribution mappings of the genus were analyzed using ArcView and DIVA-GIS software. High species richness was observed in Kurdo-Zagrosian Province, followed by Fars-Kerman, Atropatanean, and Northern Khorasan Provinces in Irano-Turanian phytogeographical region. Regarding our results, it could be concluded that effective conservation management in Kurdo-Zagrosian Province would lead to protecting a high percentage of Pseudopodospermum species against the threat of extinction.

Abstract [Persian]

مطالعه حاضر به بررسی الگوهای پراکنش جغرافیایی و ارزیابی اولویت های حفاظتی جنس Pseudopodospermum در ایران با استفاده از سامانه GIS می پردازد. مجموعه داده های جغرافیایی از طریق مطالعات میدانی، جمع­آوری داده­های موجود در فلور ایرانیکا، فلور ایران و همچنین بررسی نمونه­های هرباریومی متعدد گردآوری شد. پراکنش جغرافیایی این جنس با استفاده از نرم افزارهای ArcView و DIVA-GIS مورد تجزیه و تحلیل قرار گرفت. غنای گونه­ای بالایی در پروانس­های کرد-زاگرسی و پس از آن در فارس-کرمان، آتروپاتن و خراسان شمالی از ناحیه ایران-تورانی مشاهده شد. مقایسه نتایج حاصل از آنالیز تکمیلی نشان داد که مدیریت حفاظتی صحیح در پروانس کرد-زاگرسی منجر به حفاظت درصد بالایی از گونه های جنس Pseudopodospermum در برابر خطر انقراض می­شود.
