چکیده

طعمه‌خواری گرگ از حیوانات اهلی از‌جمله موارد معمول تضاد میان انسان و حیات وحش و یکی از دلایل انقراض این گونه در سراسر جهان محسوب می‏شود. گزارش‏های مستند حملات اخیر گرگ به دام در استان همدان نمونه‏ای از بروز این گونه تعارضات است. پژوهش حاضر به‌‌منظور شناسایی مناطق پر‏خطر برای وقوع حملات گرگ به دام و تعیین عوامل محیطی مؤثر بر این تعارض‏هابا روش مدل‏سازی حداکثر آنتروپی و به کمک نرم‌افزار MAXENT به انجام رسید. بر‌اساس نتایج حاصل مهم‌ترین عامل مؤثر در حملات گرگ به دام در این استان کاربری اراضی است. به‌علاوه در ساخت نقشۀ تعیین مناطق پرخطر، پارامترهای تراکم دام و فاصله از رودخانه از دیگر عوامل اثرگذار شناسایی شدند. بر‌اساس پیش‏بینی صورت‌گرفته، دو شهرستان بهار و کبودرآهنگ با بیشترین احتمال وقوع حملات گرگ مواجه‌اند. از نتایج این مطالعه می‏توان به‌منزلۀ یک ابزار مفید برای اجرای اقدامات حفاظتی برای کاهش تضاد گرگ با دام در مناطق پرخطر استان همدان استفاده کرد

چکیده [English]

Livestock predation by wolf is one of the most frequent sources of conflict between human and wildlife and one of the reasons for species extinction throughout the world. Recent documented reports about the wolf attacks on livestock in Hamedan province is an example of the occurrence of such conflicts. This study aimed to identify risky areas for wolves’ attacks on livestock and determination of environmental factors affecting these conflicts with maximum entropy modeling method using MAXENT software. The results showed that the most important factor is land use variable in study area. In making of map of high-risk areas, livestock density and distance from the river other effective factors are as well. According to obtained predictions, Bahar and Kaboodarahang are facing with the highest possibility of wolf attacks. Results of this study could be use as a useful tool for implementation of conservation activities for mitigation of wolf-livestock conflicts in high risk areas of Hamedan province.
