Mangrove restoration in the Philippines

Our target on this collaboration is 25,000 trees planted in the first year, as we try to turn abandoned aquaculture ponds back into healthy mangrove forests – and encourage the Philippines to push for 30 x 30.

Restoration

The challenge

Between 1970 and 2015, the Philippines lost 40 per cent of its mangroves due to aquaculture and other coastal development. Currently only 19 per cent of mangroves here are protected; the global average is 39 per cent. We hope to prove the value of mangrove restoration for biodiversity recovery using innovative monitoring techniques such as bioacoustics, as well as quantifying the benefits local communities.

 

Our strategy

Community and government members have been trained in how to restore the ecological conditions required for mangrove rehabilitation, which in this area involves raising the soil level in abandoned fishponds. By the end of Year One, approximately 25,000 trees will have been planted. To support long-term conservation and stewardship of restored areas, the local community will be supported in developing sustainable alternative livelihood models of aquaculture.   

With growing recognition of the importance of mangrove ecosystems globally and the recent launch of the Philippines National Blue Carbon Action, we believe the desire to conserve and restore of mangroves could motivate the establishment of new marine protected areas across the Philippines – a contribution towards the country’s 30 x 30 commitment. 

Our impact

  • Rehabilitation of mangroves in 10 hectares of abandoned aquaculture pond – with a further 50 hectares planned in the next 3 years
  • Focus on restoring ecological conditions for natural regeneration includes planting of 25,000 trees of various species
  • 68 community members engaged across training, mangrove nursery establishment, rehabilitation and monitoring

Work in the field

In the provinces of Surigao del Sur and La Union we are supporting Oceanus Conservation to restore abandoned aquaculture ponds to mangrove forests by following the community-based ecological mangrove restoration methodology.  

Launched in 2023 and led by our Blue Climate unit, Blue Marine’s partnership with Oceanus aims to improve biodiversity recovery, enhance climate mitigation and adaptation potential, and at the same time support the livelihoods of coastal communities. The founder and leader of Oceanus is National Geographic explorer Camille Rivera, who is quickly becoming a leading voice advocating for marine conservation in the Philippines.
