Background and objectives: The main problem of Zagros forests is the oak decline. Numerous internal and external studies have been conducted over time with valuable results in this field. To achieve a comprehensive evaluation, it is essential to compile these findings and create a universal database. This database will play a significant role in providing preliminary information for advancing future research and it can be as a guideline to facilitate current research and decision-making processes. Therefore, the main purpose of this research was to conduct and investigate all scientific research documents and publications related to the Oak decline of Zagros forests across all organizations, institutions, and academic organizations, both domestically and internationally, finally, it caused the establishment of a comprehensive database in this area.
Methodology: For accessing all published documents in this field (Oak Decline), we applied Google Scholar and for thesis and dissertations the Iran Scholar Information Database (Ganj) was utilized in national scale. Next, all Information regarding research projects carried out at the national scale was obtained by the Research Institute of Forests and Rangelands of Iran and the Natural Resources and Watershed Management Organization. Unfortunately, due to limitations, access to international projects, including thesis and dissertations, was not possible. According to the first reports related to the occurrence of oak decline date back to 1387, so the period of this research was set as a 23-year period from 1380 until 1403. Ultimately, after a thorough investigation of all documents, a relatively comprehensive database was created, and based on the obtained results, various analyses and categorizations were performed with specific objectives.
Results: The results indicated that, at both national and international levels, a total of 395 official documents have been published by researchers regarding the decline of Zagros oaks during the specified period, with the highest number attributed to Ilam province. In the subsequent section, the factors influencing this phenomenon were examined, revealing that researchers paid more attention to environmental factors compared to other aspects, focusing their studies primarily on these elements.
Among all research centers, the highest number of studies (63 documents) in this field was conducted by researchers affiliated with the Research Institute of Forests and Rangelands of Iran. Dr. Ahmad Hosseini from the Center for Agricultural Research and Education of Natural Resources in Ilam Province was recognized as the leading researcher in this area, having published 37 official documents. The Iranian Journal of Forest and Poplar Research, with 52 scientific research articles published, ranked first among all publishers in this domain.
Conclusion: According to the significant importance of this phenomenon, many researchers have conducted valuable studies in this field. The establishment of this comprehensive database can greatly assist researchers and administrators in decision-making and the allocation of research and executive funding in each province, allowing for informed actions to be taken to improve project quality. In a general evaluation, it can be pointed out that publications and citations in this field have shown a nearly positive growth during the studied time period. In conclusion, considering the importance of examining scientometric indices in various fields, especially in natural resources as a basis for life, it is recommended that researchers pay special attention to analyzing these indices and creating comprehensive scientific databases in these areas
