Restoration and Management Strategies
Site and species selection — Changing perspectivesBackgroundPlantation forestry in the tropics today is characterized by increasing refinement of matching species with site and increasing emphasis on non-industrial purposes for growing trees. This perspective comments on the increased number of objectives that a tropical forester or scientist is called upon to fulfill. Available with subscription or purchase |
Restoration of dry tropical forests in Central America: A review of pattern and processBackgroundMuch information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest, of which less than 2% remains intact.

Rationale and Methods for Conserving Biodiversity in Plantation ForestsbackgroundWhen compared to degraded lands, developed lands, or areas of intensive industrial agriculture, forest plantations can positively contribute to biodiversity conservation. However, when monoculture stands of exotic trees, or native trees not typically found in single-species stands are used for plantations, they have been found to have impoverished flora and fauna compared with natural forest.

Understory Development in Young Cordia alliodora PlantationsbackgroundThis article presents the findings of a study evaluating the biomass and composition of understory plants in 1- and 5- year old plantations at the La Selva Biological Station in Costa Rica. Reserach Goals & MethodsThis study sampled plantations of Cordia alliodora in monoculture plots and in polyculture plots with trees interplanted with monocots (Euterpe macrospadix, Euterpe oleracea, and Heliconia imbricata).

Application of Assisted Natural Regeneration to Restore Degraded Tropical ForestlandsbackgroundAssisted natural regeneration (ANR) has been proposed as an alternative restoration method that reduces the costs and scalability barriers of other restoration alternatives. This article describes the steps to applying ANR to disturbed ecosystems where forest succession processes have been halted by dominant grass or fern monocultures.

Tropical Forest Restoration: Tree Islands As Recruitment Foci In Degraded Lands Of HondurasBackgroundMethods to accelerate forest recovery must address a number of impediments including limits on seed dispersal and microclimactic extremes. This study evaluates the ability of tree islands to serve as recruitment foci for additional seeds in a two-year study in northern Honduras. Available with subscription or purchase |
Effects of Artificial Roosts for Frugivorous Bats on Seed Dispersal in a Neotropical Forest Pasture MosaicbackgroundThis article evaluates whether the installation of bat roosts into abandoned pasture sites can attract frigivorous bats into pasture areas and encourage seed rain of early-successional plant species.

Barriers to Forest Regeneration of Deforested and Abandoned Land in PanamaBackgroundThis article presents research findings on the effect of four limiting factors on tree regeneration: competition with the exotic grass Saccharum spontanaeum, seed dispersal limitation, fire, and soil nutrient deficiency. Research Goals & MethodsTreatments included prescribed grass cutting and burning, as well as the placement of plots at different distances from adjacent forest. Open access copy available |
