How Successful is Tree growing for Smallholders in the Amazon?

background

This study compares donor-driven and smallholder-initiated tree growing projects in the Amazon to assess outcomes such as tree survival, commercialization success, and environmental benefits of two different approaches to tree planting. Such research is important for understanding the limitations of both smallholder and donor-driven tree growing for reforestation, and for improving production of forest products outside of natural forests. The study also emphasizes the importance of capturing local knowledge.

Effects of Different Light Levels on the Initial Growth and Photosynthesis of Croton urucurana Baill. in Southeastern Brazil

background

This study measures the effect of different levels of shading on growth, chlorophyll concentration, and photosynthetic rate of Croton urucurana, a pioneer species potentially important in reforestation efforts in riparian forests of Brazil.

Research Goals & Methods

The authors tested seedlings at 0% shade (full sunlight), 30% shade, 50% shade, and 70% shade.

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.

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.

What Role Should Government Regulation Play in Ecological Restoration? Ongoing Debate in São Paulo State, Brazil

background

This article addresses the degree of detail that should be present in legislation dealing with reforestation and restoration, and if there is a relationship between technical content/scope of regulation and success of projects. The relationship between law and reforestation is also discussed. In São Paulo state, legislation establishes precise reforestation requirements, such as the use of a minimum of 80 species of native trees and the presence of specific proportions of functional groups. This is the only existing legislation known by the authors with this degree of technical detail.
