نابودی ۳ درصد سکویاهای کالیفرنیا در آتش‌سوزی‌های اخیر

در آتش‌سوزی‌های جنگلی امسال (۲۰۲۱) در ایالت کالیفرنیای آمریکا، حداقل سه درصد از کل درختان عظیم سکویا از بین رفته‌اند.

به گزارش ایسنا، بررسی های جدید نشان می دهد: آتش سوزی های جنگلی کالیفرنیا بین سه تا پنج درصد از کل پوشش درختی سکویا را که به درخت غول نیز شهرت دارد و گونه‌ای سوزنی‌برگ است، سوزانده و از بین برده است.

به گفته کارشناسان محیط زیستی در آمریکا، این سطح از تخریب ممکن است موجب شود که این گونه درختی، دیگر قادر نباشد به طور طبیعی رشد کند.

تخریب این گونه درختی در آتش‌سوزی‌های اخیر، اضافه بر ۱۰ تا ۱۴ درصد درخت سکویایی است که در سال ۲۰۲۰ از بین رفته اند.

به گزارش ایسنا به نقل از پایگاه خبری آکسیوس، این درختان کهنسال هستند زیرا سکویاها که بسیاری از آنها از نظر حجمی بزرگترین درختان روی زمین هستند، ممکن است چندین دهه طول بکشد تا به قطر بیش از ۱۲۱ سانتیمتر برسد.

قدیمی‌ترین این درختان در جنگل ملی سکویا در کالیفرنیا رشد یافته و ۳۰۰۰ سال عمر دارند.

گزارش‌ها حاکیست علت این آتش سوزی ها دمای بالاتر از معمول و خشکسالی شدید است. تغییر اقلیم، خطر گرمای سوزان و در نتیجه آتش سوزی های طبیعی را افزایش داده است.
