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.

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.

Screening Trial of 14 Tropical Hardwoods with an Emphasis on Species Native to Costa Rica: Fourth Year Results

Background

A lack of silvicultural information on native timber species in the tropics has contributed to the propogation of fast-growing exotic tree species in reforestation efforts. The plantations evaluated at the La Selva Biological Station in Costa Rica were considered marginal lands with low input of forest maintenance, reflecting the conditions of many lands that farmers would use for reforestation.

Survival and Growth of Under-Planted Trees: A Meta-Analysis Across four Biomes

background

This article is a meta-analysis synthesizing the results of survival and growth of under-planted trees in forests in tropical, temperate coastal, boreal, and temperate deciduous forests. Additionally, the survival and growth of these underplanted trees are evaluated according to the silvicultural treatment affecting density of the overstory: uncut, dense shelterwood, intermediate density shelterwood, light density shelterwood, clear cut.

Growth of Euterpe edulis under forest and agroforestry in southern Brazil

Background

The shade-tolerant palm Euterpe edulis is prevalent in native forests and in reforestation of banana plantations in Brazil. However, there are no data comparing its plantation growth performance to its native forest growth. This study evaluates growth and mortality of E. edulis planted in secondary dense forest and in banana plantations, as well as their relationships with site variables.

Seed development, yield and quality of two palm species growing in different tropical forest types in SE Brazil: implications for ecological restoration

Background

Natural forest remnants have been set as seed production fields to supply seeds of native tree species for tropical forest restoration, but the effect of different forest types on seed production has not been accessed to date for palm species. This study reports on seed development, yield, and quality of two palm species in different tropical forest types in SE Brazil.
