Responses of 20 Native Tree Species to Reforestation Strategies for Abandoned Farmland in Panama

Background

In the tropics, deforestation often leads to unproductive agriculture and results in degraded grasslands. This study seeks to understand why forests fail to regenerate naturally in these ecosystems.

Seed rain and seed limitation in a planted gallery forest in Brazil

Background

Seed dispersal by wind (anemochorous) and animals, usually birds and bats (zoochorous), is an important driver of succession. This study examines seed rain in a planted gallery forest (riparian corridor) in Brazil.

Isolated Trees and Grass Removal Improve Performance of Transplanted Trema micrantha (L.) Blume (Ulmaceae) Saplings in Tropical Pastures

background

This research evaluates the survival and growth of saplings of Trema micrantha when transplanted into recently abandoned pastureland in southeast Mexico. Trema micrantha is a pioneer species native to Mexico with ecological and physiological properties that would make it viable for planting in open fields.

Restoration of dry tropical forests in Central America: A review of pattern and process

Background

Much 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.

Banco de Sementes como Indicador de Restauração de uma Área Degradada por Mineração de Caulim em Brás Pires, MG

The authors germinated the seed bank from degraded former kaolin mining sites that have regenerated naturally for a period of 20 years. They used two light treatments usedfor the germination: one with 11.5% shade, and another with 60%. There was a wide range of variation among the species according to the light level, with some species producing far more seedlings under one treatment that the other. Most (2/3) of the species germinating (total n: 36) were herbaceous, with eight tree species (see above).

Tropical rainforest regeneration in an area degraded by mining in Mato Grosso State, Brazil

Background

Gold mining has been a major cause of environmental degradation in the rainforests in the north of Mato Grosso State, Brazil. Regulations on mining activity are beginning to be developed, including standards for forest recovery methodologies. This study characterizes natural tropical rainforest regeneration in Matupa County, Mato Grosso State, Brazil.

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.

Ecological Implications of Harvesting Non-Timber Forest Products

Background

This article examines 70 case studies on the ecological effects of harvesting plant-species NTFPs in an attempt to draw broader conclusions for both forest resource management and future research.
