Panjang Island is a Small Uninhabited Island Close to the city of Jepara : A Part from the Book Chapter : Assessing Planulae Recruitment in Degraded Coastal Coral of Panjang Island Jepara, Central Java-Indonesia

Coastal coral communities are prone to environmental stresses. On one hand, these stressors served as a forcing function to survive and formed the community accordingly as it may alter the community structure of the reef. Panjang Island is a small uninhabited island close to the city of Jepara, Central Java, and is one of the places in a series of marine tourism activities in the city of Jepara. The island can be visited using an engine boat. Jepara Regency has some remnants of coastal reefs and the one in Panjang Island is in a state of disrepair. This 5 months study aimed at evaluating recolonisation development of a damaged coastal coral community, using Panjang Island in Jepara Regency as a case study. Observations were made at intervals of every week for environmental variability and every 3 weeks for periphyton, bacteria and coral planula.

Bachtiar reported that survived biological structure of a reef could become the most important seed in recovering the ecosystem since the remaining components, e.g., coral species, fish and other biotic species direct the succession of new coral communities. The better the remnant, the more similar the recovered community will be. A coral remnant may provide attachment preference for benthic organisms including its planulae and indeed serve as a nursery ground, even a habitat for various species.

Recent Global Research Developments in Ecosystem management for Coral

Coral Reef Monitoring, Reef Assessment Technologies, and Ecosystem-Based Management:

• This article discusses monitoring techniques, assessment technologies, and management strategies for coral reefs. It emphasizes the need to integrate ecosystem-based management and resilience thinking [1].

Evaluating management strategies to optimize coral reef ecosystem services:

• This study evaluates different management interventions in relation to sustaining or improving ecosystem services provided by coral reefs, including ecosystem structure, dive tourism, and fisheries [2].

An Integrated Coral Reef Ecosystem Model:

• The Atlantis Ecosystem Model is adapted to incorporate key dynamics for a coral reef ecosystem around Guam. It provides insights into complex reef dynamics and responses to disturbances, supporting ecosystem-based management [3].
