Forest Plantations
On the Restoration of High Diversity Forests: 30 years of Experience in the Brazilian Atlantic ForestbackgroundThis review evaluates the restoration of Brazil's Atlantic forest by drawing from published and unpublished sources. Reforestation in Atlantic Brazil took place in phases: government-sponsored plantations predominated until 1982; a focus on native species plantations from 1982-1985; higher diversity of species used from 1985 to 2000; a focus on restoring process rather than copying the structure of natural forests from 2000-2003; and finally a conscious effort to improve intraspecific genetic diversity and seed acquisition from 2003 to today.

Determinants for Successful Reforestation of Abandoned Pastures in the Andes: Soil Conditions and Vegetation CoverBackgroundThis article compares the growth of native and exotic species seedlings planted in abandoned pasture and among brachen ferns and shrubs in Andean Ecuador over three years. Research Goals & MethodsThe species (native: Alnus acuminata, Cedrela montana, Juglans neotropica, Heliocarpus americanus, Tabebuia chrysantha, exotic: Pinus patula and Eucalyptus saligna) were planted in a block design in the different successional stages and in plots with and without above-ground weeding.

Tree planting by small producers in the tropics: A comparative study of Brazil and PanamaBackgroundForest regrowth is a widespread phenomenon across the tropical forest latitudes. Such reforestation takes place in the wake of land abandonment, occurs cyclically in a rotational agricultural system, and may result from the deliberate planting of trees by farmers. Although less extensive than successional forest regeneration, tree planting by small farmers can have potentially important environmental impacts at both the site and global scale.

Growth, carbon sequestration, and management of native tree plantations in humid regions of Costa RicaBackgroundThe Costa Rican government has provided incentives for reforestation programs since 1986 and initiated a Payment for Environmental Services program in 1996. These incentives yielded native species reforestation programs throughout the country. This study examines growth, carbon sequestration, and management of seven native tree species (Vochysia guatemalensis, Vochysia ferruginea, Hyeronima alchorneoides, Calophyllum brasiliense, Terminalia amazonia, Virola koschnyi, and Dipteryx panamensis) in single-species plantations managed by small landowners.

Influence of Overstory Composition on Understory Colonization by Native Species in Plantations on a Degraded Tropical SitebackgroundThis study evaluates forest understory regeneration in a 4.5 year-old plantation in Puerto Rico. The plantations, established in 1989, were planted on abandoned pasture in mixtures or monocultures of three exotic species: Casuarina equisetifolia, Eucalyptus robusta, and Leucaena leucocephala.

The Role of Native Species Plantations in Recovery of Understory Woody Diversity in Degraded Pasturelands of Costa RicabackgroundThis study analyzes the understory recruitment success of tropical timber plantations in order to understand biodiversity recovery on degraded lands through the use of fast-growing timber plantations. The study takes place in the Atlantic humid lowlands of Costa Rica. Open access copy available |
Reforestation and Regrowth in the Human Dominated Landscapes of South AsiabackgroundThis study evaluates the drivers of reforestation and regrowth in South Asia using case studies and a meta-analysis of 24 papers. Available with subscription or purchase |
Leaf Litter Decomposition and Mulch Performance from Mixed and Monospecific Plantations of Native Tree Species in Costa RicabackgroundThis research looks at leaf litter decomposition rates and mulch performance of four native tree species in mixed and monospecific plantations at the La Selva Biological Station in Costa Rica. The four species considered were Callophylum brasiliense, Jacaranda copaia, Vochysia guatemalensis, and Strypnodendron microstachyum. The faster the decomposition, the faster the nutrient transfer from the trees into the soils for uptake by other trees or by crops when the leaves are used as mulch.
