Propagación in vitro de material seleccionado de Tabebuia rosea y Cordia alliodora (In vitro propagation of selected material from Tabebuia rosea and Cordia alliodora)EspañolAntecedentesLa aplicación de la micropropagación y otras técnicas biotecnológicas a las especies forestales maderables ha representado un enfoque útil para aumentar el número de plantas necesarias para el establecimiento de plantaciones de restauración. En Colombia se está investigando la integración de esta tecnología para la siembra de importantes especies maderables nativas como Tabebuia rosea y Cordia alliodora. Open access copy available |
Seed germination and seedling establishment of Neotropical dry forest species in response to temperature and light conditionsBackgroundSite conditions in restoration projects vary widely, with proper conditions for germination not always available for a given species. This study examines the germination requirements of Cedrela odorata, Guaiacum sanctum and Calycophyllum candidissimum seeds under varying light conditions beneath the canopy of a dry forest in Nicaragua.

Approaches to Classifying and Restoring Degraded Tropical Forests for the Anticipated REDD+ Climate Change Mitigation MechanismbackgroundForest degradation from logging and fires has impacted millions of acres of tropical forest around the globe, reducing the ability of these forests to provide ecosystem services, sequester carbon, and provide habitat to endangered species. This report focuses on the UN’s REDD + initiative (reducing emissions from deforestation and forest degradation) and calls for more attention to the potential for restoration initiatives of degraded forests to act as carbon sinks.

A Strategy for Restoration of Montane Forest in Anthropogenic Fern Thickets in the Dominican RepublicBackgroundThis study looked at the potential of different tree species to grow in clearings in fern-dominated thickets in a state of arrested succession. It was conducted in the Ébano Verde Scientific Reserve in the Dominican Republic with subtropical montane forest. Research Goals & MethodsThe authors cleared fern-dominated shrubs with machetes and planted 18 species of early and late successional trees and shrubs with and without a single application of fertilizer.

Secondary Forest Regeneration Under Fast-Growing Forest Plantations on Degraded Imperata cylindrica GrasslandsBACKGROUNDIn Southeast Asia, large areas of former rain forest lands are covered by fire-climax Imperata cyclindrica (alang-alang) grass. Grass has potential to colonize varying types and sizes of land preventing regrowth of woody species. Natural forest recovery is inhibited by fires and competition with grass and shrubs. Planting fast growing tree species can create needed micro-climate and speed up regeneration of woody species. This study compared the regeneration of native tree species under the canopy of tree plantations, riverine areas, and uncultivated grassland areas. Available with subscription or purchase |
Can Intensive Management Accelerate the Restoration of Brazil’s Atlantic Forests?backgroundThis study takes place in the heavily degraded Atlantic Forest region of eastern Brazil, where only 7% of the original forest cover remains. The study tests the question of whether intensive management methods similar to those used to establish fast-growing Eucalyptus plantations could also be applied to restoration of rainforest on former pasture-land dominated by grasses.

Mycorrhizal Interactions for Reforestation: Constraints to Dryland Agroforest in BrazilbackgroundThe authors conducted a review of literature on mycohorrizae in tropical dry forest systems. Their objective was to understand the role that reforestation and mycohorrizae play in providing ecosystem services such as carbon sequestration and flood control. Research Goals & MethodsFew studies describe the role of mycohorrizae in tropical dry forest; this study seeks to fill that gap. Open access copy available |
Regeneration of Five Combretaceae Species along a Latitudinal Gradient in Sahelo-Sudanian Zone of Burkina FasoBackgruondThis study examines seedling density and regeneration processes of 5 species of Combretaceae across latitudinal gradients in the Sahelo-Sudanian ecoregion in Burkina Faso. Species were chosen based on their economic importance and large distributions. Rainfall varies across the area studied from 400-900 mm annually with elevations of about 300 m. The vegetation in the area is strongly seasonal with mostly deciduous trees and most herbacious species dying back during the dry season. Open access copy available |
Environmental Drivers in Mangrove Establishment and Early Development: A reviewbackgroundThis study reviews literature on the environmental conditions that influence the establishment and early growth of mangroves. Research Goals & MethodsDifferent species grow in areas with different flooding regimes. The authors used the classification of "inundation by all high tides, inundation by medium high tides, inundation by normal high tides, inundation by spring tides, and occasional inundation by exceptional or equinoctial tides."
