Croissance et assimilation nette foliaire de jeunes plants de dix arbres de la forêt guyanaise, cultivés à cinq niveaux d'éclairement

background

This study assesses the growth of ten species of tropical rainforest trees under 5 different light conditions.

Conclusions & Takeaways

The authors find that juveniles of most species did best in 25-45% sun light conditions and that the lowest light levels severely decrease growth across species.

Growth in pure and mixed plantations of tree species used in reforesting rural areas of the humid region of Costa Rica, Central America

Background

Despite government incentives in Costa Rica for establishing and maintaining native tree plantations since the 1990s, farmers and small landowners often lack adequate knowledge about plantation management. Yield and rotation periods for each of the ten most common species grown in monoculture have previously been published. This paper compares productivity in monoculture and mixtures at La Selva Biological Station in the Caribbean lowlands of Costa Rica.

Seeding ecological restoration of tropical forests: Priority setting under REDD+

Background

Tropical deforestation continues to be the major driver of biodiversity loss and a considerable contributor to climate change. Increasing numbers of forest-dependent rural poor rely on degraded forest for their livelihoods. Ecological restoration of tropical forests has the potential to not only contribute to biodiversity conservation and climate mitigation, but also poverty alleviation. REDD+ provides a potentially powerful mechanism for supporting ecological restoration of tropical forests in developing countries.

Plantaciones forestales con especies nativas: Una alternativa para la producción de madera y la provisión de servicios ambientales (Native species tree plantations: and alternative for wood production and environmental services)

Se presenta un panorama general del desarrollo de las actividades de plantaciones forestales en Costa Rica, así como algunos resultados de ensayos de rehabilitación de áreas degradadas con especies forestales nativas en la Estación Biológica La Selva. Durante 12 años, se midió anualmente el crecimiento y la producción de biomasa aérea de doce especies nativas en rodales mixtos y puros, como asi también la fertilidad del suelo bajo plantaciones puras de cuatro especies forestales nativas. La mezcla de especies mostro la mayor productividad volumétrica, estadísticamente superior a las especies en plantaciones puras.

Strategies for the Recovery of Degraded Ecosystems: Experiences from Latin America

background

This paper reviews the rehabilitation potential of native species forest plantations in lowland Costa Rica, the Atlantic Forest of Bahia, Brazil, and sub-tropical Argentina. Native species can improve forest regeneration where soils are degraded and where sources of propagules are limited. While most tropical plantations are dominated by exotic species, native trees may be more appropriate because they are better adapted to the local environment, are already familiar to local farmers, and their propagules are locally available.

Silvicultural and economic aspects of pure and mixed native tree species plantations on degraded pasturelands in humid Costa Rica

Background

Reforestation of degraded land in tropical regions provides one means of restoring ecosystems and improving rural livelihoods. Most plantations in humid tropical regions are established in pure plots using few species of high commercial value, generally exotics. This study compares growth and economic viability of native trees in pure and mixed plantations on degraded land.

A Comparative Study of Tree Establishment in Abandoned Pasture and Mature Forest of Eastern Amazonia

Background

This study compares seedling establishment, seed availability, seed predation, seedling herbivory, and abiotic barriers to tree establishment in recently abandoned pasture, treefall gaps, and mature forest understory in Pará State, Brazil.
