Between and Within-Site Comparisons of Structural and Physiological Characteristics and Foliar Nutrient Content of 14 Tree Species at a Wet, Fertile Site and a Dry, Infertile Site in PanamabackgroundAvailable with subscription or purchase |
Initial Performance and Reforestation Potential of 24 Tropical Tree Species Planted Across a Precipitation Gradient in the Republic of PanamabackgroundThe authors of this study planted trees from 22 native species and two exotic species to use in selection trials testing the growth and survivability of trees in plantations in three different sites.

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.

Especies para reforestación en Nicaragua (Species for Reforestation in Nicaragua)BackgroundThis manual provides information about multipurpose trees in Nicaragua. Available with subscription or purchase |
Local and Regional Environmental Variation Influences the Growth of Tropical Trees in Selection Trials in the Republic of PanamabackgroundThis study evaluates the effect of varying site conditions on the basal area of 21 neotropical and 2 exotic tree species at three different sites in Panama. Available with subscription or purchase |
Attempting Restoration of Wet Tropical Forests in Costa RicaBackgroundThis article describes a reforestation effort of the Tropical Forestry Initiative using mixed stands of native species to recover abandoned pastureland in the tropical wet forest of Costa Rica.

The Structure and Composition of a Tropical Dry Forest Landscape After Land Clearance; Azuero Peninsula, PanamabackgroundAvailable with subscription or purchase |
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.

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. Available with subscription or purchase |
Profiles of Carbon Stocks in Forest, Reforestation and Agricultural Land, Northern ThailandbackgroundThis study evaluates the difference in above-ground and below-ground carbon stock between forest, reforestation, and agricultural land in northern Thailand. Available with subscription or purchase |
Species-Specific Tree Water Use Characteristics in Reforestation Stands in the PhilippinesBackgroundThe need for reforestation is becoming increasingly evident in countries like the Philippines where deforestation has lead to a scarcity of wood and other forest commodities. One concern with reforestation is the reduction in streamflow and groundwater recharge as trees move water from the ground into the atmosphere. 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 |
Early Growth Performance of Native and Introduced Fast Growing Tree Species in Wet to Sub-Humid Climates of the Southern Region of Costa RicabackgroundThe authors present information on the growth of seven-year-old native tree species planted in abandoned pasture with low fertility acidic soils in the southern pacific region of Costa Rica. Research Goals & MethodsThe study evalutes trees in four ecoregions of varying elevation and precipitation. Available with subscription or purchase |
Effect of Nurse Tree Species on Early Growth of Anisoptera marginata Korth. (Dipterocarpaceae) on an Imperata cylindrica (L.) Beauv. Grassland Site in South Kalimantan, IndonesiabackgroundThis study evaluates the survival of Anisoptera marginata, a native dipterocarp species, underplanted in four year old plantations of fast-growing exotics: Acadia crassicarpa, Acacia mangium, Gmelina arborea, Paraserianthes falcataria. Available with subscription or purchase |
Selecting framework tree species for restoring seasonally dry tropical forests in northern Thailand based on field performanceBackgroundFramework tree species are indigenous forest tree species, planted to complement and accelerate natural regeneration of forest ecosystems and encourage biodiversity recovery, on degraded sites. This study tests the extent to which 37 native forest tree species might act as framework tree species to accelerate recovery of evergreen, seasonal forest in a degraded upper watershed in Doi Suthep-Pui National Park in northern Thailand. Open access copy available |
Growth of native forest species planted on abandoned pasture land in Costa RicaBackgroundReforestation programs in Costa Rica have largely utilized only four tree species. This study tests growth rates and form of eleven additional tree species native to the humid tropics, including five N-fixing species and six non-N-fixing species. 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 |
Poverty reduction in the Doi Mae Salong LandscapeBackgroundThe Doi Mae Salong Landscape has experienced deragadation in ecosystem services due to a variety of reasons along with the significant poverty and high risk to climatic variations. The IUCN partnered with the Supreme Commander’s Office of the Royal Thai Armed Forces to pursue forest restoration and support local livelihoods. The program ran from 2010 to 2013 in the Chiang Rai Province of Thailand. Open access copy available |
