Status Monitoring of the
Seagrass beds of Palawan
Jesus E. Bream
Background of the study
• Since 1989, our office called PIADPO back then
was already conducting coastal resource
assessment on the municipalities in Palawan.
• Worldwide, a total of 60 species of seagrass have
been identified.
• 16 in the Philippines and 13 in Palawan.
Background of the study
• Are submerged flowering marine plants
• Serves as nursery, feeding habitat and breeding
grounds
• Ecologicially as important as mangroves, and
coral habitats
Study location
21 municipalities
13 in the North and
8 in the South
Objectives
1. To conduct a comparative analysis on the
baseline and monitoring data of the seagrass
beds of Palawan
2. To make a trending analysis on the condition of
the seagrass resources in the past 15 years
3. To provide the concerned LGU’s with information
to formulate ordinances for protected areas.
Methodology
1. The Transect quadrat sampling method was used
in all the assessment and monitoring activities
used in this study.
2. The method used was by English et al., (1997)

Recommendations
1. Intensive information education campaign (IEC)
on the role of seagrass on the marine ecosystem
2. Strict protection, monitoring, and inclusion in
marine protected areas (MPAs) of the seagrass beds
3. Incorporating adaptive measures on the effects of
climate change on our coastal communities and
resources
