Razul S. Pagrangan and Mark Joseph J. Buncag of CFES-MSU Marawi published a 2026 paper in the International Journal of Science and Management Studies (IJSMS), Vol. 9, Issue 4. The study surveyed the diversity, composition, and community use of natural mangrove stands in Barangay Barorao, Balabagan, Lanao del Sur, with relevance to SDG 14, SDG 15, and SDG 13.
Some key takeaways:
🔽The team recorded 751 individual mangrove trees across 10 species from seven families, though a Shannon diversity index of 1.343 places the site under very low diversity.
🔽Four species, 𝐴𝑒𝑔𝑖𝑐𝑒𝑟𝑎𝑠 𝑐𝑜𝑟𝑛𝑖𝑐𝑢𝑙𝑎𝑡𝑢𝑚, 𝐵𝑟𝑢𝑔𝑢𝑖𝑒𝑟𝑎 𝑠𝑒𝑥𝑎𝑛𝑔𝑢𝑙𝑎, 𝑅ℎ𝑖𝑧𝑜𝑝ℎ𝑜𝑟𝑎 𝑎𝑝𝑖𝑐𝑢𝑙𝑎𝑡𝑎 and 𝑆𝑜𝑛𝑛𝑒𝑟𝑎𝑡𝑖𝑎 𝑎𝑙𝑏𝑎, were present across all transects, while others like 𝑁𝑦𝑝𝑎 𝑓𝑟𝑢𝑡𝑖𝑐𝑎𝑛𝑠 were far less common.
🔽Local communities rely heavily on the mangroves, mainly for food (88%) and materials like lumber and furniture, and strongly favor protective measures — 100% supported prohibiting tree-cutting, and 80% supported replanting seedlings.
