Among parameters calculated were rank abundance and diversity index. There were 12 species representing 8 families of mangroves in Carmen, 11 species from 9 families in Tagum, and 16 species from 10 families in Panabo, repesctively. Species dominance values were low at 0.1596 (Carmen), 0.1836 (Tagum), and 0.2333 (Panabo). The Shannon H indices were low: 2.067 (Carmen), 1.968 (Tagum), and 1.906 (Panabo). Species evenness was highest in Carmen (0.6584) and lowest in Panabo (0.425). Rhizophora mucronata (Rhizophoraceae) and Avicennia marina (Avicenniaceae) were the top species found in the three municipalities. Both are species of Least Concern under IUCN classification. Ceriops decandra (Rhizophoraceae), a Near Threatened species was recorded in Panabo, whereas Avicennia rumphiana (Avicenniaceae), a Vulnerable species was recorded from all three municipalities. Majority of the spec...
