AHNRA conservation group of Small Malaita is venturing into mangrove rehabilitation.
The Mangrove Rehabilitation initiative is a key component of the Apunepara Ha’amwaora Natural Resources Association’s (AHNRA) strategic development plan for 2021 to 2035.
AHNRA grants and programme manager, Grayham Tahu told this paper that this initiative aims to restore and rehabilitate degraded mangrove forests.
Mangrove forests that are affected by human activities such as; deforestation, pollution, and shoreline development, and natural factors like climate change and extreme weather events like hurricanes and rising sea levels.
“To achieve its goals, the initiative employs two main methodologies. The first involves the careful collection of seedlings from select parent mangrove trees known for their desirable traits, such as larger fruit size, unique colouration, and faster growth rates. This selection process ensures that the seedlings carry healthy genetic material, which is essential for successfully planting in degraded areas.
“The second method focuses on seed collection, followed by germination in a controlled nursery environment. This nursery is monitored rigorously to maintain optimal conditions, including humidity, temperature, and light, which maximise germination rates and support seedling health. The nursery phase is crucial for ensuring that the seedlings are prepared for effective transplantation into their natural habitats,” Mr Tahu said.
He said that the initiative also prioritises understanding the natural distribution patterns and ecological roles of different mangrove species.
He said that this knowledge informs decision-making regarding the strategic placement of various tree species in specific locations within the mangrove area.
“By selecting locations that match the natural preferences of each species—such as salinity levels, soil type, and water availability the initiative aims to enhance biodiversity, strengthen ecological resilience, and promote the health of the mangrove ecosystem overall,” he said.
He said that the Mangrove Rehabilitation Initiative seeks to restore critical ecosystems while safeguarding their vital environmental services, including coastal protection, carbon sequestration, and habitat provision for diverse marine life.
Tahu said that the AHNRA stresses the importance of local communities along the Maramasike passage to engage in comprehensive shoreline rehabilitation efforts.
