Abstract:
This study investigates the impact of super
typhoon Pablo on mangrove forests in Barangay Lucod,
Baganga, Davao Oriental. The mangroves in this area
were severely affected by the typhoon, causing damage to
individual trees and altering the overall ecosystem structure.
The study aimed to assess the damaged and recovered
mangroves in the affected area by measuring various
parameters such as tree height, canopy branch length, and
density. The study also assessed the density, relative density,
frequency, and relative frequency of mangrove species,
providing insights into their distribution patterns and
abundance within the study area. Mangrove measurements
were conducted using standard quadrat sampling methods,
with four quadrats established within the study area. The
results showed that the mangrove of quadrat 2 had the
tallest tree which reached 8.5 m. among all quadrats. In
canopy branch length, quadrats 3 and 4 have plants with
longer branches (5.26 m and 3.6 m). In terms of density,
Rhizophora apiculata and Rhizophora stylosa have
(0.4 Ind/m2
) including Xylocarpus granatum (0.4 Ind/m2
).
Additionally, the percentage of recovered (55%) and
damaged mangroves (45%) in the different quadrats
highlighted the ongoing recovery process following the super
typhoon. The study contributes valuable information for
understanding the impact of natural disasters on mangrove
ecosystems and assessing their resilience and recovery
mechanisms. The findings can aid in the development of
effective conservation and rehabilitation strategies for
mangrove forests in typhoon-prone regions in the Philippines.
