Assisted Natural Regeneration
Fallow to Forest: Applying Indigenous and Scientific Knowledge of Swidden Cultivation to Tropical Forest RestorationBackgroundThis study analyzed vegetation at two sites of shifting cultivation by Lawa and Karen indigenous people in the Mae Chaem watershed in 1-year, 3-year and 6-year fallow fields, with an area of natural forest as a control comparison.

Testing Applied Nucleation as a Strategy to Facilitate Tropical Forest RecoveryBackgroundThis study considers applied nucleation, or the intensive planting of small patches of a mixture of successional species, as a degraded tropical forest restoration strategy. This approach catalyzes the natural regeneration of the surrounding matrix and larger landscape and could provide a less expensive alternative to the more common, and expensive, plantation-style approach. This study claims to be the first to directly compare tree recruitment beneath these two restoration approaches. Open access copy available |
Management of the environmental restoration of degraded areasBackgroundThis study shares the results of an experimental method for restoration of degraded forest areas through the construction of small restoration ‘islands’ within a larger site as an impetus for further natural regeneration. The method has previously been used in Namibia and Spain and is trademarked as Revitec. This study tests the method in Brazil in a former rainforest area. Rainforest fragments remain in the area.

Regeneration Status of Mangrove Forests in Mida Creek, Kenya: A Compromised or Secured Future?BackgroundThis 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 & MethodsA stratified sampling technique was used in two main study areas. Transects and quadrants were used to measure vegetation measurements, species density, and frequency.

Seed rain under tree islands planted to restore degraded lands in a tropical agricultural landscapeBackgroundPlanting native tree seedlings is the predominant restoration strategy for accelerating forest succession on degraded lands. However, planting tree “islands” is less costly and labor intensive than establishing larger plantations and simulates the nucleation process of succession. Tree islands can attract seed dispersers to gradually spread restoration patterns from the islands. Restoration design can be informed by assessing the effect of potential planting arrangements on seed dispersal by birds and bats and determining the influence of surrounding forest cover.

Restoration of the Cerros Orientales de Bogota - Jardin Botanico de BogotaThe Jose Celestino Mutis Botanic Garden of Bogota works with the Municipal government of Bogota in order to restore and rehabilitate various areas of forest habitat around the city of Bogota. The most extensive plantings are conducted in the Cerros Orientales, hills located on the outskirts of Bogota. This very steep mountain area had been cleared and was subject to severe erosion, and was planted with exotic pine and eucalyptus throughout the 19th and 20th century. Parts of this forest continue to be grazed for cattle, and many areas have also been invaded by the invasive European gorse (Ulex europaeus). Open access copy available |
Memorias del I Congreso Colombiano de Restauración EcológicaBackgroundThese proceedings summarize the 11 Master Conferences at the "I Congreso Colombiano de Restauración Ecológica y II Simposio de Nacional de Experiencias en Restauración" in 2009. It includes information from dozens of forest restoration projects in Colombia. Most projects are restoration experiements with native species forest restoration in the montane zone of Colombia, although some reports describe projects in lowland humid forest, dry forest, and high mountain páramo.

Adaptabilidad y crecimiento de especies nativas en areas en recuperacion del noroeste de la provincia de Misiones (Adaptability and growth of native species in recovery areas in the northwest of the province of Misiones)BackgroundThis study takes place in the Argentinean province of Misiones, where there was a high level of land degradation and strong need for reforestation to restore productivity to the landscape.

Efecto de la zona de vida y la altitud en la mortalidad y adaptabilidad al primer año de especies forestales en la Cordillera Volcánica Central de Costa RicaEspañolAntecedentesEl entendimiento comprensivo de la restauración de bosques requiere de la comprensión del fenómeno de la mortalidad incluyendo su magnitud y ubicación espacial. En Costa Rica, no existe suficiente información capturando los efectos de climas pluviales sobre la mortalidad de especies forestales, especialmente en zonas altas. Open access copy available |
