In this study the biodiversity and relative abundance of Collembola was evaluated in two different ecosystems, citrus field and forest in Mazandaran province, Iran. Samples were carried out during 2016 and 2017. In each site, soil was sampled by a collecting core from 5×5 cm in surface area and a depth of 10 cm. Species richness, biodiversity and the indices of similarity were calculated. The results of T-Test showed that in two years (2016 and 2017), the values of Shannon-Wiener diversity and Simpson species diversity index were significantly different between sampling areas (Pvalue<0.05), but the values of Margalef richness and Pielou evenness index were not significantly (Pvalue˃0.05). In the year 2016, Shannon-Wiener index, Simpson index, Pielou evenness and Margalef species richness in Dasht-e Naz forest were 1.92 ± 0.1, 0.83 ± 0.03, 2.01 ± 0.2 and 0.94 ± 0.04 respectively, and in citrus field were 1.44 ± 0.11, 0.73 ± 0.02, 1.46 ± 0.37 and 0.9 ± 0.03 respectively. Also, in the year 2017, Shannon-Wiener index, Simpson index, Pielou evenness and Margalef species richness in Dasht-e Naz forest were 1.79 ± 0.05, 0.81 ± 0.08, 1.38 ± 0.25 and 0.94 ± 0.09 respectively, and in citrus field were 0.98 ± 0.22, 0.58 ± 0.08, 1.02 ± 0.35 and 0.95 ± 0.05 respectively. In general, the results showed that the abundance and biodiversity of Collembola in Dasht-e Naz forest was higher than in citrus field.
