Evaluation and Planning of Mangrove Restoration Programs in Sedari Village of Kerawang District, West Java: Contribution of PHE-ONWJ Coastal Development Programs

Background

The authors described a mangrove restoration project in Sedari Village of Kerawang District, West Java. According to the article, the main cause for mangrove degradation in this region is due to brackish water fish ponds called “tambak”. The authors described and evaluated the first four of six project phases through mangrove survivability and soil structure.

Preliminary assessment of post-Haiyan mangrove damage andshort-term recovery in Eastern Samar, central Philippines

Background

In this study, authors examined the natural ability of mangrove trees to recover after major storms and supertyphoons in the Philippines. Coastal mangroves are important for reducing the damage from these storms.

Mangrove restoration without planting

Background

Mangrove planting is the most common method of restoring mangrove forests. However, this approach is not often successful, especially when the causes of mangrove degradation were not removed prior to planting new seedlings or propagules. A successful mangrove restoration project may not necessarily include a planting phase. When the stressors are removed and suitable environmental conditions are present, natural regeneration processes could recover mangroves from degradation.

Regeneration Status of Mangrove Forests in Mida Creek, Kenya: A Compromised or Secured Future?

Background

This study investigates natural regeneration and timber potential of the mangrove forests of Mida Creek for better management through the principle of sustained yields.

Research Goals & Methods

A stratified sampling technique was used in two main study areas. Transects and quadrants were used to measure vegetation measurements, species density, and frequency.

Structural Properties of Two Types of Mangrove Stands on the Northwestern Coast of Sri Lanka

background

This article compares the structural diversity of six mangrove stands of both estuarine and island-fringing types in Puttalam lagoon and Dutch Bay in northwestern Sri Lanka.

Research Goals & Methods

Using belt transects, the authors measured floristic composition, tree height and leaf-area index and calculated density, basal area and mean stand diameter. Standing above-ground biomass was also measured and compared to dbh using destructive sampling methods.

A review of the floral composition and distribution of mangroves in Sri Lanka

Background

The article reviews literature on the numbers and distributions of Sri Lankan mangrove species and highlights the causes of overestimation. It also attempts to provide an accurate count based on standardized fieldwork over a 4-year period along the coast between Palatupana and Puttalam, Sri Lanka. The authors name some examples of mischaracterized or misidentified species from previous studies and address the importance of clearly defining the terms for mangroves.

Net Primary Productivity of Two Mangrove Forest Stands on the Northwestern Coast of Sri Lanka

Background

This article compares the net primary production of an estuarine mangrove stand to an island fringing stand in Dutch Bay in northwestern Sri Lanka.

Research Goals & Methods

Net above-ground primary productivity was measured by monitoring litterfall and above-ground biomass increment between 1985 and 1987.

Influence of species richness and environmental context on early survival of replanted mangroves at Gazi bay, Kenya

Background

Mangrove restoration is often unsuccessful, thus this study involves long-term large-scale experiments measuring a range of ecosystem functions in replanted mangrove stands in Ghazi in Kenya funded by Earthwatch.

Colonization of Non-Planted Mangrove Species into Restored Mangrove Stands in Gazi Bay, Kenya

Background

As mangroves are being recognized as some of the world’s most productive ecosystems, restoration efforts are being undertaken around the world. Not all projects are successful, however. This study will potentially help mangrove restoration practitioners with species selection.

Sustainable Management of Mangrove Resources through a Participatory Approach - Kenya

background

This study reviews an ongoing mangrove restoration project in the Ghazi region of Kenya. The study seeks to improve the sustainable development and conservation of mangrove forests in order to enhance productivity of natural resources in ways that sustain continuous flow of desired forest products and services. All 10 mangroves found in the Indian Ocean region are found in Ghazi. The dominant mangroves in the Ghazi area are Rhizophora mucronata, Ceriops tagal and Avicennia marina.
