T H E L O S T F O R E S TRestoring the Ecological State of Angke Kapuk Mangrove Forest,

North Jakarta, Indonesia

The coastal abrasion processes due to the current has caused the coastline along North Jakarta coast retreating further to the south. As a result, the 100 meter width and 1.780 meter length coastal area along the Angke Kapuk Mangrove Forest “has disappeared’ in recent years.

The above picture shows the condition of of coastal line along the Angke Kapuk Mangrove Forest that has been degraded by abrasion.

The Lost Forest is a documentation photography on the initiative movement of community who joins ‘Sahabat Bakau’ in restoring the environmental conditions of the lost mangrove forests. Ecological restoration movement of Angke Kapuk Forest aims at reviving the mangrove ecosystems and its wildlife, providing access to acknowledge and educate the public about the mangroves and its habitats. This movement also opens up opportunities in the utilization of mangrove forests for the benefit of communities in the vicinity.

Who is ‘Sahabat Bakau’?

‘Sahabat Bakau’ is a movement to attract public attention as well as public concern on the ecosystem and environmental conditions about its function and preservation, are threatened particularly for the mangrove forest ecosystem. As an informal community of environmentalists, ‘Sahabat Bakau’ seeks partnership and collaborate with various other environmentalist communities, in an effort to restore the mangrove ecosystem in the north of Jakarta which has been degraded by nature.

To regain the mangrove ecosystem, several groups of stakeholders who are members of ‘Sahabat Bakau’ have raised an initiative to implement Ecological Restoration Program of Angke Kapuk Forest. The movement is also expected to encourage community initiative and participation in joint efforts to undertake the restoration of mangrove forests and preserve its function.

This slug hatches from eggs some species has several adaptations for living in dry conditions. They search for food nearly at night, and stay buried in the soil during the day. Larger specimens are active during the day sometimes. This slug can grow up from 0.5 cm to approximately 4 cm in length in 7 months.

Lugworms feed on decayed organic matter and ingest sand along with the food particles. At low tide their coiled casts (masses of excrement) may often be seen piled above their burrows. Their burrows may extend as deep as 60 cm (2 feet). The animals are hermaphroditic; i.e., functional reproductive organs of both sexes occur in the same individual. The eggs of one individual, however, are fertilized by the sperm of another.

Sunning can dislodge feather parasites because the excess heat will encourage insects to move to other places in a bird’s plumage. It is essential to get rid of these parasites – the tiny insects that infect feathers can cause problems for a bird’s flight, insulation and appearance, all of which can impact its survival.
