Diversity of the Orchard Species in Iran: A Case Study of Khorasan Province
Author(s):
Abstract:
Agrobiodiversity is an issue that has been considered for the last decade. There are few reports on diversity of orchard species in Iran and some available reports have not mentioned the relevant indices and analysis results. In the current study, based upon data collected from 29 provinces of Iran along with 23 counties of Khorasan provinces, a comprehensive analysis was made and different diversity indices such as Shanon- Weaver, Evenness index, Margalof richness index as well as two dominance indices including Sympson and Berger-Parker were calculated. The results indicated that Kerman, Fars and Khorasan provinces cover 40% of orchard areas in the country. Species richness in all provinces was relatively high but the evenness index was not so (average evenness for all provinces is 0.55). Therefore, in some provinces such as Boshehr and Kerman, species dominance is observed due to Date and Pistachio, respectively. Also, Stone fruits among Khorasan orchards provided the highest richness and diversity. The highest area of orchards in Khorasan are belonged to nuts including Pistachio, Almond, Walnut and Oleaster. Kashmar district has the highest orchards area in Khorasan province. According to the Shanon-Weaver index, the highest and lowest diversity were observed at Nahbandan- Birjand and Fariman counties. Results also indicated that the Berger-Parker dominance index is highest at Fariman and Shirvan districts of Khorasan because of apple and grape species dominance.
