Abstract :
Soil is a vital component in the growth and development of plants. Understanding the
relationship between mangrove diversity and soil composition might improve rehabilitation efforts in the
study area. The study employed a purposive sampling in the rehabilitated mangrove landscape in
Hagonoy, Davao del Sur. A total of 20 quadrates (10 m x 10 m) were installed. Mangrove species and soil
samples were identified and collected. The results revealed 7 species belonging to 5 families of mangroves
in the quadrates. Gravel was the most dominant substrate and Avicennia marina the most dominant
species. Diversity is expected to be high in very coarse sand substrate (Pearson correlation ρ = 0.272).
Using the principal component analysis, PC1 and PC2 gave 77.3% cumulative variation. The data
suggested variability between soil structure and species diversity in quadrates
