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 |
An Evaluation of Farmers' Experiences Planting Native Trees in Rural Panama: Implications for Reforestation with Native Species in Agricultural LandscapesbackgroundOpen access copy available |
Linking Multiple-Level Tree Traits with Biomass Accumulation in Native Tree Species used for Reforestation in PanamabackgroundThis research presents the links between biomass accumulation, plant traits, and functional groups for five native species in abandoned pasture of central Panama. Open access copy available |
Is Tree Diversity an Important Driver for Phosphorus and Nitrogen Acquisition of a Young Tropical Plantation?backgroundThis article presents the effect of native species diversity on the nitrogen and phosphorous pools above-ground in a plantation in the Canal Zone of Panama.

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. Open access copy available |
The Agua Salud Project, Central PanamaBackgroundThe Agua Salud Project is located in the watershed that includes and surrounds the Panama Canal, an engineering feat that largely relies on natural hydrological systems. Much of this watershed has been deforested, thus an official policy has been put into place to reforest and regain ecosystem services. This project seeks to utilize the globalize role of the canal to bring attention to the ecosystem services of the region. Open access copy available |
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. Available with subscription or purchase |
Pure and Mixed Forest Plantations with Native Species of the Dry Tropics of Costa Rica: A Comparison of Growth and ProductivitybackgroundThis research monitored the growth and survival of 13 natives species in pure and mixed-species plantations, and compared the results to measurements of T. grandis, an exotic species commonly planted in the area. Open access copy available |
A Survey of Small-Scale Farmers Using Trees in Pastures in Herrera Province, PanamabackgroundThe Herrera Province on the Azuero Peninsula of Panamá has experienced significant deforestation for the purpose of cattle ranching. Available with subscription or purchase |
Foliar herbivory and leaf traits of five native tree species in a young plantation of Central PanamaBackgroundTimber plantations often provide economic incentives for land owners to restore abandoned pastures or agricultural land to forest, yet the threat of insect herbivory can diminish these new plantations and compromise the efforts. This study seeks to understand the extent of these threats on tree plantations in Panama. Open access copy available |
