چکیده

در این پژوهش اثر فرم‌های مختلف پرستاری روی استقرار زادآوری طبیعی در جنگل‌های وزگ حوزة شهرستان بویراحمد بررسی شد. عرصه‌ای به مساحت شش هکتار انتخاب و نوع گونه و فرم پرستاری و نوع گونة هدف (زادآوری)  بررسی شد. در مجموع 14 گونه چوبی پرستار به تعداد 423 اصله در منطقة پژوهش ثبت شد که در بین آن­ها دو گونة خاردار ارژن (Amygdalus lycioides Spach.) و گلابی‌وحشی (Pyrus glabra Boiss.) به­ترتیب با 195 و 77 اصله بیشترین تعداد را به­خود اختصاص دادند. همچنین از تعداد 912 اصله زادآوری (گونة هدف) موجود در زیر تاج‌پوشش گیاهان پرستار و سنگ‌ها بیشترین تعداد به گونه‌های دافنه (Daphne mucronata Royle.)، ارژن، گیلاس‌وحشی (Prunus Sp.) و شن (Lonicera nummularifolia Jaub. & Spach) تعلق داشت. تحلیل RDA نیز نشان داد زادآوری گونه‌های هدف تحت تأثیر گیاهان پرستار ارژن و گلابی وحشی است. نتایج این پژوهش نشان داد زادآوری گونه‌های چوبی در این منطقه به‌استثناء گونة ارژن به حفاظ و پرستار وابسته است. این موضوع بیانگر نقش گونه‌های پرستار در استقرار زادآوری در جنگل‌های نیمه‌خشک زاگرس است که می‌تواند به‌عنوان یک الگو در برنامه‌های احیاء جنگل در دیگر مناطق زاگرس استفاده شود.

چکیده [English]

In this research, the effect of different forms of nursing on establishment of natural regeneration in the forests of Vezg region in Boyer-Ahmad basin was investigated. For this purpose, an area of six hectares was selected and the type of nurse species and forms, the type of target species (regeneration) were measured. Overall, 14 woody species of nurse plants with a total of 423 individuals were recorded in the research area, among them, two thorny species include Amygdalus lycioides and Pyrus glabra with 195 and 77, respectively, have the highest number. Also, out of 912 regeneration individuals (target species) under the canopy of nurse plants and rocks, the highest number belonged to Daphne mucronata, Amygdalus lycioides, Prunus sp and Lonicera nummulariifolia. RDA analysis also showed that the regeneration of target species is affected by A.lycioides and P.glabra nursing plants. The results of this study showed that the regeneration of woody species in this area, with the exception of A. lycioides, depends on conservation and nursing. This indicates the role of nurse species in establishing regeneration in semi-arid forests of Zagros, which can be used as a model in forest restoration programs in other parts of the Zagros forests‎.
