The growth and evolution of mangrove forests are affected by various factors such as pollution, light penetration, depth, water flow, and water quality. The effects of sea surface temperature and salinity on vegetation changes in the Khor-e-khoran protected area was been investigated in two distinct time periods (1986-1999 & 2001-2015) which were used as recorded data in the department of environment of Iran, as well as satellite imagery, drawing profiles and charts by standard models, ECMWF and Giovanni. The results clarified that Sea Surface Temperature and Salinity increased by about 0.2°C and 0.5 ppt respectively. On the other hand, the area of Khor-e-khoran protected area was decreased from about 6800 hectares in 2003 to 6350 hectares in 2015 which was more than 1.5%. Additionally, it is suggested sewages and wastewaters delivered from shrimp farming pools as well as fuel and crude oil leakage caused salinity and pollution anomalies.
