| تجدید حیات گیاهان بهشدت حساس به استرسهای ناشی از عوامل زنده و غیرزنده در طبیعت است. موفقیت استقرار گیاهان در طبیعت به عوامل مختلفی مانند خشکی، چرای دام، در دسترس بودن منابع آب و خاک و اثر متقابل افراد بر همدیگر به‌ویژه در سنین نهال بستگی دارد. تعریف گیاه پرستار، اثر گیاه پرستار، رقابت و تسهیلگری و نقش تسهیلگری در احیای سرزمین به کمک منابع علمی بیان شد. به کمک جنگل‌گردشی و بررسی منابع علمی، گیاهان پرستار و گیاهان هدف در جنوب ایران شناسایی و نقش هر یک به کمک منابع علمی در دسترس بررسی گردید. برای این منظور از حاشیه خلیج‌فارس و دریای عمان در مسیرهایی که راه دسترسی داشت، تا ارتفاع 1250 متر از سطح دریا در قطعات نمونه یک هکتاری (100*100 متر) اقدام به بررسی پوشش گیاهی شد. گیاهان زیر تاج سایر درختان یا درختچهها نمونه‌برداری و به‌کمک منابع علمی شناسایی شدند. نتایج این تحقیق نشان داد، تعداد نه گونه متعلق به هشت جنس و شش خانواده به‌عنوان گیاه پرستار و هفت گونه متعلق به شش جنس و شش خانواده به‌عنوان گیاه هدف شناسایی شدند. از گروه گیاهان پرستار جنس Ziziphus Mill. از خانواده Rhamncaceae متنوعترین بود. از گروه گیاهان هدف نیز متنوعترین جنس، Pistacia L. متعلق به خانواده Anacardiaceae بود. تحقیقات تکمیلی برای بیان اثر تسهیلگری گونههای گیاهی پرستار و روشهای مناسب استفاده از آنها در احیای اکولوژیکی مناطق خشک جنوب ایران در رابطه با اجرای طرحهای احیا و توسعه جنگل پیشنهاد شد. | ||

| چکیده [English] | ||
| Plant reproduction is highly sensitive to stressors caused by both biotic and abiotic factors in nature. The success of plant establishment in the wild depends on various factors such as drought, grazing, availability of water and soil resources, and the mutual interactions among individuals, especially during the seedling stage. The concept of nurse plants, their effects, competition, facilitation, and the facilitative role in land restoration were explained using scientific sources. Through forest surveys and scientific resources, nurse plants and target plants in southern Iran were identified, and the role of each was examined with available scientific references. For this purpose, along the Persian Gulf and the Sea of Oman, accessible pathways were chosen to investigate vegetation cover up to an altitude of 1250 meters above sea level in sample plots of one hectare (100 * 100 meters). Sampling was conducted beneath the canopy of other trees or shrubs, and the plants were identified using scientific sources. The results of this study revealed that nine species belonging to eight genera and six families were identified as nurse plants, and seven species belonging to six genera and six families were identified as target plants. Among the nurse plant group, the genus Ziziphus Mill. from the family Rhamnaceae was the most diverse. Among the target plant group, the most diverse genus was Pistacia L. belonging to the family Anacardiaceae. Further research is recommended to explore the facilitative effects of nurse plant species and suitable methods for their use in the ecological restoration of dry areas in southern Iran in relation to the implementation of restoration and forest development projects. | ||
