The Potentials of 20 Indigenous Tree Species for Soil Rehabilitation in the Atlantic Forest Region of Bahia, Brazil

background

This research presents the effects of 20 native tree species planted in 1974-1975 on different soil conditions in Bahia, Brazil.

Research Goals & Methods

In pure stands of the native species (some nitrogen-fixing) as well as a nearby 25 year old secondary forest, primary forest, and mixed-species plantation, soils were evaluated for the following conditions: depth, % carbon, % nitrogen, phosphorous, potassium, calcium, magnesium, dry weight of forest floor litter, pH, and nodules.

Restoration of seasonal semideciduous forests in Brazil: influence of age and restoration design on forest structure

Background

With the high rates of deforestation in tropical regions, the restoration of degraded lands has become an important way for maintaining the diversity of plant communities and for creating wildlife habitats. Evaluating the success of restored areas is essential for improving restoration designs and for successfully restoring such complex 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.

Restoration of a Restinga Sandy Coastal Plain in Brazil: Survival and Growth of Planted Woody Species

Background

Restingas – coastal sandy vegetation – have been affected by human impact for about 8,000 years. Human use of these sites for housing, tourism, and recreation has recently increased in such a way that there is a need for conservation of remnant patches and restoration of degraded areas throughout the coast to protect biodiversity. This study reports the results of an experiment introducing 17 native shrub and tree species into a degraded Brazilian restinga.

On the Restoration of High Diversity Forests: 30 years of Experience in the Brazilian Atlantic Forest

background

This review evaluates the restoration of Brazil's Atlantic forest by drawing from published and unpublished sources.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.
