Promoting Biodiversity: Advances in Evaluating Native Species for ReforestationbackgroundThis article describes the design of a long-term species screening trial conducted at La Selva Biological Station in Costa Rica. Research Goals & MethodsGrowth and survivability data is presented for 84 species (17 popular exotics used for timber and 67 little-known local species with timber potential) at 3 years of age.

Reforestation of Abandoned Pastures: Silvicultural Means to Accelerate Forest Recovery and BiodiversityBackgroundDespite the 2736 native tree species in Ecuador, the majority of forestation activities in the country are based on exotic pines and eucalypts. In this book chapter, the authors describe the reason for this neglect being the lack of knowledge on the ecology and silvicultural treatment and the lack of nurseries growing these species.

Manual of Reforestation and Erosion Control for the PhilippinesbackgroundThis manual provides a detailed guide to reforestation, including information about species selection, nursery techniques, site preparation and plantation design, weed and fire control, stand improvement and other practical aspects of establishing and managing tree plantations. Additionally, there is a large portion devoted to erosion control, using trees and engineered structures to stabilize slopes and decrease the velocity of water runoff. Open access copy available |
Native Tree Species Regeneration and Diversity in the Mountain Cloud Forests of East AfricabackgroundThis study evaluates the diversity of native species regeneration within 3 native and exotic forest plantations of the indigenous forests of Tatia Hills, East Africa. Open access copy available |
Exotic Trees as Nurse-Trees for the Regeneration of Natural Tropical ForestsBackgroundThis article challenges widely-held views that the presence of exotic tree plantations in the tropics harm the environment. Through collecting evidence from experiences in tropical countries, the authors argue that exotic tree canopies exert protective functions - a nurse effect - for the regeneration of natural forest. Open access copy available |
Native Forest Regeneration in Pine and Eucalypt Plantations in Northern Province, South AfricabackgroundThis study assesses understory colonization by indigenous plant species in exotic tree plantations established on grasslands growing adjacent to native mixed evergreen forest in Northern Province, South Africa. Available with subscription or purchase |
Status of Indigenous Tree Species Regeneration under Exotic Plantations in Belete Forest, South West EthiopiabackgroundThis study assesses the diversity and density of naturally regenerated woody species under the canopies of exotic plantations adjacent to natural forests in a moist montane forest type in Southwest Ethiopia. Open access copy available |
Native Woody Species Regeneration in Exotic Tree Plantations at Munessa-Shashemene Forest, Southern EthiopiabackgroundThis study investigates native woody species regeneration in 4 exotic species monoculture plantations in Munessa-Shashemene Forest Project Area in southern Ethiopia. The plantation ages ranged from 9 to 28 years. Available with subscription or purchase |
Analysis of the "Shelter Tree-Effect” of Natural and Exotic Forest Canopies on the Growth of Young Podocarpus falcatus Trees in Southern EthiopiabackgroundAvailable with subscription or purchase |
Effects of Canopy Cover and Understory Environment of Tree Plantations on Richness, Density and Size of Colonizing Woody Species in Southern EthiopiabackgroundThis study investigates the effects of canopy characteristics and associated understory environmental factors of tree plantations on native woody species colonization in two broadleaved and two coniferous plantations in southern Ethiopia. The plantation forests investigated are surrounded by dry Afromontane natural forest. Available with subscription or purchase |
Early Species Selection for Tropical Reforestation: A Consideration of StabilitybackgroundThis study describes a screening of timber species planted in abandoned pasture sites to understand the effect of different site conditions on tree growth and to determine the species that grew with the highest variation. Available with subscription or purchase |
Native Species: A Resource for the Diversification of Forestry Production in the Lowland Humid TropicsbackgroundThis research evaluates the success of native species for reforestation plantings in Costa Rica in comparison with exotic species. 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.

Restoration of a Sri-Lankan rainforest: Using Caribbean Pine Pinus caribaea as a nurse for establishing late-successional tree speciesBackgroundIn the moist tropics, studies have demonstrated poor seedling establishment of late-successional trees on lands cleared of forest. This study examines the potential for establishing late-successional tree species that dominate the canopy of rainforest by planting within and adjacent to experimental openings that were created within a Pinus caribaea plantation.

Impact of Exotic Plantations and Harvesting Methods on the Regeneration of Indigenous Tree Species in Kibale Forest, UgandabackgroundIn the late 1960s and early 1970s, exotic tree plantations were established in hilltop grassland sites of the Kibale Forest Reserve. In the late 1990s and early 2000s, many of these sites were selected for logging to encourage growth of native trees. Available with subscription or purchase |
Does Weeding Promote Regeneration of an Indigenous Tree Community in Felled Pine Plantations in UgandabackgroundThis study evaluates a management scheme to cut vines, grasses, and shrubs to promote regeneration of indigenous trees subsequent to removal of plantation softwoods over a period of 3 years in Kibale National Park, Uganda. Available with subscription or purchase |
Understory Vegetation in Fast-Growing Tree Plantations on Savanna Soils in CongobackgroundThe study investigates the hypothesis that tree plantations established adjacent to natural forests may catalyze the regeneration of natural forest biodiversity in the Congo. Available with subscription or purchase |
Expediting Reforestation in Tropical Forests Grasslands: Distance and Isolation from Seed Sources in PlantationsbackgroundThis study investigates the potential use of tree plantations to facilitate regeneration of indigenous trees in successionally arrested grassland. It focuses on how characteristics of the plantations and native species can determine the type of regeneration occurring in Kibale National Park, Uganda. Open access copy available |

Reforestation with Native Species in the Dry Lands of PanamaBACKGROUNDNatural populations of precious timber species in Panama are being overexploited, and some have been registered in the IUCN Red List in recent years. Within the overall framework of natural resource scarcity and mounting effects of climate change, the need for sustainable production of native trees that offer added values of water cycle regulation, soil improvement, and biodiversity conservation is stressed.
