International Mangrove Ecosystem Conservation Day July 26, 2023- Sri Lanka

International Mangrove Ecosystem Conservation Day 2023       


Mangrove is the only tree that grows in saltwater. Mangrove forest is a rare but spectacular and prolific ecosystem, which is usually found along sheltered coastlines in the tropical and sub-tropical regions.  Globally, mangrove forests represent less than 1% of all tropical forests and less than 0.4% of the total forest estate. However, mangrove forests are extraordinary, with some featured and even unique functions:

  1. Mangroves can offer a considerable array of ecosystem goods and services, so contribute to the wellbeing, food security, and protection of coastal communities.
  1. Mangroves can protect coastlines from storm surges, tsunamis, and rising sea levels. They also protect coral reefs, sea grass beds and shipping lanes against siltation and erosion. Thus, mangroves increase resilience to natural hazards.
  1. Mangroves can support or conserve a rich biodiversity, since they provide nursery habitat, spawning grounds and nutrients for a variety of fish, shellfish, migratory birds, and insects as well as countless endangered mammals, reptiles, and amphibians. 
  1. Mangroves are also an important tool in the fight against climate change. They take up to five times more carbon out of the atmosphere than forests on land. 

Despite Sri Lanka being a medium-sized island, numerous distinct ecosystems can be found in a relatively small space. Among them, the mangrove ecosystem has been identified as a highly threatened ecosystem, although it is an extremely important, rare ecosystem with a low distribution.

In Sri Lanka, 21 true mangroves and mangrove associates have been identified. In Here,   the most significant fact is although one third of the world's mangrove species are represented in Sri Lanka's ecosystems, 10 of the 21 true mangrove species have been threated. Nowadays this unique ecosystem become a highly threatened due to various human activities. Among them clearance of mangrove forests, reclamation projects, solid waste disposal, conversion of mangrove swamps to aquaculture systems and salterns and unsustainable coastal developments serves a major threats.

Accordingly, as the focal point of the Convention on Biological Diversity, the Ministry of and Environment has been implementing programs to aware the state, public and private institutions, school children and the community on conservation and sustainable utilization of Mangrove ecosystems and also Sri Lanka is functioning as leader among the Commonwealth Countries on mangroves conservation.

Furthermore, conservation of the mangrove ecosystem has been highlighted globally as a priority, and the UNESCO Conference held in 2015 aimed to improve awareness of the importance of the unique, special and threatened mangrove ecosystem and inspire solutions for its sustainable management, conservation and use. Every year 26th of July was declared as International Mangrove Ecosystem Conservation Day.

International Mangrove Ecosystem Conservation Day serves as reminder of the crucial role of mangrove ecosystem. Since 2015 various parties, non-governmental organizations and interested stakeholders have come together on 26th July every year around the world to raise awareness and promote the need for international cooperation to conserve the mangrove ecosystem and promote innovative solutions to ensure the sustainable management, conservation and utilization of mangroves by various activities on International Mangrove Ecosystem Conservation day.

Therefore, the Biodiversity Secretariat has been conducted the following program with the collaboration of other relevant parties and scholars to celebrate the International Mangrove Ecosystem Conservation Day.

  1. National Program :“Let's streamline Future Generations to ensure the survival of mangroves to ensure our survival

Practical workshop on Conservation and Sustainable Utilization of Mangrove Ecosystem for School Children   26th July, 2023 at 8.30 a.m.

A practical workshop was conducted at the Ministry of Environment premises to educate school students on the importance of mangrove ecosystem, identification of mangrove species, distribution, causes of threats and conservation. The programme was conducted for 200 students and 220 teachers each represented 10 schools in the Western Province.


The future of the mangrove ecosystems is depending on the knowledge of the future generation and the way they protect their ecosystems. The main objective of this program is to educate the future generation about the value of mangrove existence and create a generation that will protect the mangrove ecosystem.

Here, a practical experience was provided regarding the importance of the mangrove ecosystem, identification of mangrove species, distribution, reasons for being threatened and conservation, and with the contribution of the school students, they drew a picture to represent the value of the mangroves themselves.

With the knowledge gained from this awareness workshop, eco-pilot projects on mangrove conservation were launched and school students, including eco-pilots, were targeted in the hopes of imposing interest in carrying out activities to protect this ecosystem at their level by involving adults as well. It was also expected that the participated students and teachers, together with other government and private institutions, would prepare the necessary background to implement such activities in their schools.

The programme was conducted for 200 students and 220 teachers each represented 10 schools in the Western Province.
