in Api-Api Village, Bengkalis Regency. This study used survey method. Experimental
plots were determined by purposive sampling with a plot size of 10 m x 10 m. Results

of substrate, salinity, pH, temperature and light intensity. Those environmental factors
influence the distribution of mangrove tree strata in Api-Api Village, Bengkalis
Regency. R. apiculata species were distributed throughout the zone, E. agallocha was
