n a continuous endeavor to restore and conserve critical
coastal ecosystems, the Coastal Conservation and
Education Foundation has teamed with many companies
to carry out mangrove rehabilitation initiatives in
Cotcot Liloan, Cebu, since 2010. However, the program has
experienced several challenges that are now being addressed
to increase its effectiveness and assure the initiative’s longterm
viability.
Species Biodiversity
One of the key issues identified is the lack of diversity in the
mangrove species being planted. Across all planting sites,
partner companies have focused solely on planting Avicennia
marina, locally known as Miyapi or Bungalon. While Avicennia
marina is a strong mangrove species, promoting biodiversity
by incorporating other species is vital for coastal ecosystems’
overall health and resilience. Miyabi
Planting Spacing
Despite the limited species diversity, the planting spacing
of 0.5m x 0.5m in a zigzag pattern adheres to the standard
mangrove rehabilitation protocols. However, an additional
concern arises from the initial height of the seedling materials
used, which is below the recommended 50cm requirement
for seafront planting. This shortfall could potentially impact
the survival and growth rate of the mangrove seedlings.
Suitability of Substrate
Furthermore, the mid-portion planting site has proven
unsuitable for replanting due to the shifting sandy substrate
influenced by the nearby river mouth outflow. Sadly, this
natural occurrence has resulted in the burial of 89% of the
500 mangrove seedlings planted by LEAR in January 2023.
The careful selection of suitable planting sites is crucial for
the long-term success of mangrove restoration efforts.
Caretakers reuse little

whenever feasible and
use them as plant bags.
Additionally, they gather
sand and mud deposits
from the beach and store
them in their backyards
for later use.
