| چکیده | ||
| امروزه خشکه‌دارها به‌عنوان یک بخش ساختاری و کاربردی بسیار مهم در جوامع جنگلی شناخته شده‌اند. درک نقش و پویایی خشکه‌دارها به‌منظور بهبود راهبردهای مدیریت جنگل در جنگل‌های مدیریت‌شده و مدیریت‌نشده بسیار حائز اهمیت است. پژوهش پیش‌رو با هدف بررسی ویژگی‌های کمی و کیفی خشکه‌دارها در مرحله میانی توالی در توده‌های کمتردست‌خورده آمیخته راش (Fagus orientalis Lipsky) انجام شد. پس از جنگل‌گردشی اولیه، سه قطعه‌نمونه یک‌هکتاری در پارسل 310 بخش گرازبن جنگل خیرودکنار نوشهر انتخاب شدند و آماربرداری صددرصد از ویژگی‌های خشکه‌دارها شامل قطر (≥ 7/5 سانتی‌متر)، ارتفاع و مشخصات کیفی (شامل شکل، درجه پوسیدگی و گونه) انجام شد. براساس نتایج پژوهش پیش‌رو، حجم خشکه‌دار در قطعات مورد بررسی به‌طور متوسط 37/8 متر مکعب در هکتار اندازه‌گیری شد. ممرز با 64 درصد خشکه‌دار، بیشترین فراوانی را در بین خشکه‌دارها به‌خود اختصاص داد. بیشترین درصد فراوانی و حجم خشکه‌دارهای اندازه‌گیری‌شده به‌ترتیب 74/7 درصد و 69/3 درصد مربوط به خشکه‌دارهای افتاده بود. همچنین 52/1 درصد خشکه‌دارهای اندازه‌گیری‌شده، در درجات پیشرفته پوسیدگی قرار داشتند. درنهایت بیشترین فراوانیخشکه‌دارها در طبقه قطور(50 تا 75 سانتی‌متر) مشاهده شد. | ||

| چکیده [English] | ||
| Deadwood is widely recognized as an extremely important structural and functional component of forest communities. Therefore, understanding its role and dynamics are important to improve forest management strategies in both managed and unmanaged forests. The aim of this study was to analyze the qualitative and quantitative characteristics of dead trees in the mid-succession stage in intact mixed oriental beech (Fagus orientalis Lipsky) forests of Kheyrood,, Mazandaran province. Three one-ha sample plots were laid out in compartment 310 of Gorazbon district, in which a number of quantitative (diameter at breast height≥7.5cm and height) and qualitative (species, type of deadwood (log or snag) and decay class) characteristics were recorded. Our results indicated the mean volume of deadwood of 37.8 m3 ha-1. In addition, common hornbeam (Carpinus betulus L.) possessed the highest frequency (64%) of the deadwood among the species. The frequency and volume proportions of logs were 74.7% and 69.3%, respectively, and the maximum amount of deadwood was observed in the large timber size (50-75 cm). As conclusion, forest management planning should pass an adequate attention to succession stage and the amount of deadwood to guarantee the health, long lasting productivity and sustainability of forest ecosystem. | ||
