Nucleation in tropical ecological restoration

background

Due to centuraries of human development, there is a need to restore degraded areas and reconcile productive uses of land with conservation goals. One means of ecological restoration is facilitation, which aims to accrue positive interactions between species. Nucleation has been shown as a effective stategy for facilitation.

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.

The tree planting and protecting culture of cattle ranchers and small-scale agriculturalists in rural Panama: Opportunities for reforestation and land restoration

Background

Deforestation rates are high in mesoamerican, particularly within dry forests, thus threatening the regions biodiversity and livelihoods of local peoples. To address these trends, there has been a push to support and promote farming strategies that are compatible with conservation goals, particularly those that pursue a range of activities. This study focuses in Panama where these strategies are expanding and examines the tree planting and land protecting activities of cattle ranchers and small-scale agriculturalists.

Ecological restoration success is higher for natural regeneration than for active restoration in tropical forests

background

This meta-analysis of 133 studies challenges the widely-held notion that active restoration methods are more effective at ecosystem restoration and hold higher conservation value than natural regeneration. Given the vast commitments for ecosystem restoration across the globe, and the high cost, effort, and resources needed for these commitments, this study proposes that increasing use of natural regeneration and assisted natural regeneration is necessary to achieve these commitments.

Restoration of Degraded Tropical Forest Landscapes

Background

Deforestation and the declining extent of tropical forests has negatively impacted ecosystem functions, services, and goods and has disproportionately harmed the rural poor of tropical countries. In the wake of deforestation, agricultural development and traditional methods of reforestation (plantations) have largely failed to provide sustainable livelihoods. This review article assesses the strengths and weaknesses of different tropical restoration methods to combat forest degredation and address rural poverty.

Restoration of native forests from Japan to Malaysia

Background

This paper describes the "Miyawaki method" to afforestation and its application in an urban setting in Malaysia. This method, which relies on a densley planted mix of seedling species from seeds collected in neighboring forests, has been utilized throughout Japan and is gaining momentum in new tropical locations as well.

Rio Bogota - Fundacion al verde vivo

This project attempts to restore riparian forest along the headwaters of the Rio Bogota, upstream of the city of Bogota.

Since 2003, the Fundacion al verde vivo has worked with volunteers to plant trees along the riparian corridor. Many areas along the riverbanks were previously used for cattle pasture, leather tanneries, or other small constructions. Local laws require that certain distances of riparian buffer are maintained as forest, but these regulations are rarely enforced.

Plantings are conducted in rows with 1-2 meter spacing. Alnus plantings from 2005 form a canopy, and mid-successional species of oak, Spanish cedar, and other highland Andean trees are planted in gaps and in the understory.
