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.

Propagación vegetativa de tres especies de mangle por acodos aéreos en el manglar de Sontecomapan, Catemaco, Veracruz, México (Asexual propagation of three species of mangroves in Veracruz, Mexico).

Los autores evaluaron la propagación asexual por acodos aéreos en las especies Rhizophora mangle (Rhizophoraceae), Laguncularia racemosa (Combretaceae) y Avicennia germinans (Avicenniaceae) bajo el supuesto de que una planta de mangle propagada por acodo puede ser de mayor altura y más rápido crecimiento.

La propagación asexual en especies de mangle está escasamente documentada en la literatura y ha consistido en la propagación vegetativa de algunas especies sin existir continuidad y mayor investigación debido a los resultados poco favorables.

Are Mangroves Worth Replanting? The Direct Economic Benefits of a Community-Based Reforestation Project

background

This study examines the socioeconomic impacts of a community-led reforestation project in the Philippines through a survey of the local fishers over 10 years after replanting. The wider objective of the study was to obtain greater data on the local economic value of mangroves and present it as a comparison to other land uses such as development and aquaculture.

Plan de restauración de los manglares en Puerto Villamil Isla Isabela – Galapagos (Plan for restoration of mangroves in Galapagos)

Español

Antecedentes

Los manglares brindan servicios ambientales importantes incluyendo la protección de costas contra el oleaje, la provisión de hábitat para especies marinas y el establecimiento de áreas de recreación turística. Sin embargo, los manglares alrededor del mundo se ven amenazados por el desarrollo de costas. En las islas Galápagos, la acumulación de residuos sólidos en las raíces de los manglares y la construcción de hoteles, viviendas, puertos y malecones, constituyen las fuentes principales de presión sobre estos ecosistemas.

Monitoring of Black Mangrove Restoration with Nursery-Reared Seedlings on an Arid Coastal Lagoon

background

This paper describes a reforestation experiment with black mangrove (Avicennia germinans) in an arid mangrove forest of Baja California Sur, Mexico. In arid mangrove systems, natural regeneration and small-scale reforestation are not adequate to restore mangrove forests, as they may be in the humid tropics. Thus, alternative nursery techniques for arid mangroves must be developed.

Plant Growth-Promoting Bacteria: A Potential Tool for Arid Mangrove Reforestation

background

Microbes (bacteria and fungi) play a crucial role in nutrient recycling in mangrove systems, which are nutrient deficient. Microbes make nutrients, especially nitrogen and phosphorous, available to mangroves, while mangroves may improve soil conditions for microbes (for example, by oxidizing the soil). PGPB may be nitrogen fixers, phosphate solubilizers, mineral uptake enhancers, and phytopathogen controllers.

Reforestation of Mangroves after Severe Impacts of Herbicides during the the Viet Nam War: The Case of Can Gio

background

This article describes the detrimental impacts of chemicals used in the Viet Nam war on mangroves with a focus on the reforestation efforts of the mangroves of the Can Gio district. In the 1980s, poor management, combined with stress from fuelwood collection and conversion to shrimp ponds, limited the success of mangrove restoration. Between 1978 and 1989,29,583 ha of Rhizophora apiriculata were planted; however, due to a lack of technical experience and a very high planting density, by 1990 only 18,125 ha remained. 35,000 ha of mangrove were replanted by 1996 and, in 2001, about 20,000 ha still survived.

Reasons for reforestation success and failure with three mangrove species in Colombia

Background

This study examines the mortality and growth rates of the propagules, seedlings and saplings of three native mangrove species (A. germinans, L. racemosa, and R. mangle) in order to determine the ecological factors that influence tree growth and survival in deforested mangroves with restored hydrologic conditions on the Caribbean coast of Colombia.

The Global Conservation Status of Mangroves

background

This research evaluates mangrove stands in 16 countries and island states throughout the neo- and paleotropics. Relying on site visits, the authors evaluate the local impacts on mangroves and the attitudes toward mangroves.
