گرگاس تهدیدی برای حیات وحش

 با افزایش جمعیت کره زمین در عصر حاضر، انسان برای حفظ و ادامه زندگی خود، جانداران زیادی را از کره خاکی از بین برده و با دستکاری در طبیعت اکوسیستم های طبیعت را دگرگون کرده است.

علاوه بر تخریب جنگل، آلودگی آب و خاک و مراتع و خشک کردن تالابها به صورت مستقیم و غیر مستقیم نسل بسیاری از حیوانات را از بین برده اند یا در معرض نابودی قرار داده اند، یکی از این موارد که در این سالها با ورود دام و سگ گله به مناطق حفاظت شده بیشتر دیده می شود بوجود آمدن نژاد ناخالصی است که شبیه سگ و با خصوصیات گرگ می باشد.
به نقل از روابط عمومی اداره کل محیط زیست خراسان شمالی ، گونه جدیدی که به این ترتیب به چرخه طبیعت وارد می شود برای طبیعت و انسان خطرناک می باشد.
تصاویر بدست آمده از دوربین های تله ای نصب شده در مناطق تحت مدیریت محیط زیست بیانگر این موضوع است که نژاد گرگ ناخالص(گرگاس) در طبیعت رو به افزایش بوده و در بسیاری از موارد در حمله به دام ها این گونه پیشرو می باشد.
گرگاس علاوه بر ضررهای اقتصادی که برای انسان دارد به عنوان گونه ای جدید و رقیب سایر گوشتخواران موجود در مناطق مانند یوزپلنگ، کاراکال، پلنگ و …. بوده که در رأس هرم غذایی می تواند باعث به هم خوردن تعادل زیست محیطی شوند.
بررسی های کارشناسی در چندین مورد از شکایت حمله گرگ به دامداری های حاشیه شهر بجنورد در سالهای اخیر نشان دهنده این است که این حملات توسط گرگاس انجام شده است.
توله های حاصله از آمیزش گرگ و سگ ظاهری شبیه گرگ و سگ و درندگی گرگ را دارند و آنها تهدیدی جدی برای دام های اهلی و حیات وحش محسوب می‌شوند
ناآگاهی برخی از افراد در خصوص بدست آوردن یک نژاد بهتر برای سگ نگهبان باعث شده به اختلاط دو گونه سگ و گرگ روی آورند که این توله ها(گرگاس) بعلت داشتن خصوصیات درندگی گرگ نهایتا توسط این افراد ناآگاه رها می‌شوند که این امر باعث بوجود آمدن مشکلاتی در خصوص حمله این گونه هیبرید به حیات وحش، دام‌های اهلی و برخی موارد به انسان گردیده است.
