Mangrove communities usually occur in the intertidal zone within tropical and subtropical coastal zones in sheltered saline to brackish environments. It is difficult to monitor and manage mangroves due to a lack of baseline data on the mangrove stmctural properties in the Persian Gulf and Oman Sea. This study investigated the structure of mangrove forests in the Hormozgan province, south of Iran. This study was performed in the Hara Protected Area (HPA) and Gaz and Hara Rivers Delta (GHRD), using random 5-m x 5-m quadrates. A total of 101 Avicennia marina trees in HPA and 172 Rhizophora mucronata trees in GHRD were measured. The average density, tree height, diameter at breast height, crown spread, canopy index, above ground biomass, and litterfall were 1005 ± 68.11 stem ha-1, 2.51 ± 0.17 m, 17.44 ± 0.8 cm, 1.97 ± 0.16 m, 56.06 ± 2.85 (%), 72 ± 9.8 t ha-1 and 9.4 ± 8.5 t ha-1 yr-1 for the A. marina stands, respectively, while 1110.77 ± 182.58 stem ha-1, 2.78 ± 0.46 m, 11.73 ± 1.50 cm, 1.39 ± 0.06 m, 78.54 ± 2.4 (%), 66 ± 11 t ha-1, 5.1 ± 6.9 t ha-1 yr-1 were recorded for R. mucronata stands, respectively. The density, tree height, and canopy of R. mucronata were higher than A. marina (p < 0.05). The diameter at breast height, crown spread, above ground biomass, and litterfall were higher at A. marina habitat. All parameters except tree height were significantly different between HPA and GHRD habitats. Due to the different structure of A. marina and R. mucronata along the Hormozgan coast of Persian Gulf and Oman Sea, the best management strategies to conserve these productive habitats are required.
