What Role Should Government Regulation Play in Ecological Restoration? Ongoing Debate in São Paulo State, BrazilbackgroundThis 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. Open access copy available |

Soil Responses to restoration of a tropical pasture in Veracruz, South-Eastern Mexico.BackgroundChanges in land use and land cover may affect soil properties and processes. Conversion of forest to pasture is assumed to result in a decrease in soil nutrients. Restoration to healthy grassland or forest may lead to an increase in soil nutrients. This paper reports on a study on soil responses to restoration of a tropical pasture in Veracruz, Mexico. Available with subscription or purchase |
Growth Increments of Indigenous Species Planted in Secondary Forest AreaBackgroundAppropriate species selection for reforestation of degraded lands in the tropics makes a great difference in survival rates and success in establishing secondary forest. Indigenous species used in reforestation are not always able to survive in their native landscapes based on the degree of site degradation. This paper reports on growth increments of five tree species indigenous to Malaysia five years after planting. Open access copy available |
Releasing Rain Forest Succession: A Case Study in the Dicranopteris linearis Fernlands of Sri LankabackgroundThis study evaluates the effectiveness of different site treatments for controlling the invasive fern Dicranopteris linearis which has arrested forest succession in areas of the Sinharaja Man and Biosphere (MAB) reserve in lowland Sri Lanka. The fernlands, which had existed in the reserve for 10-20 years before this study, are favored by forest clearance for swidden agriculture and periodic fires.

Role of Legumes in Release of Successionally Arrested Grasslands inthe Central Hills of Sri LankaBackgroundMany cleared and abandoned forest areas have changed to successionally arrested grasslands, shrublands, or fernlands maintained by frequent fires and high herbivore populations. Many studies have shown that herbaceous legumes can protect soil surfaces, retain soil moisture, improve soil fertility, and retard ground fires. This study evaluates whether some of these species can satisfactorily establish in these arrested grassland areas to aid in the trajectory towards reforestation.

Local and Regional Environmental Variation Influences the Growth of Tropical Trees in Selection Trials in the Republic of PanamabackgroundThis study evaluates the effect of varying site conditions on the basal area of 21 neotropical and 2 exotic tree species at three different sites in Panama. Research Goals & MethodsSeedlings were planted in 2003 in randomized blocks and measured for basal diameter, height, live crown length, and crown diameter each year from 2004 to 2006.

The Tree Planting and Protecting Culture of Cattle Ranchers and Small-Scale Agriculturalists in Rural Panama: Opportunities for Reforestation and Land RestorationbackgroundThis study examines the relationship between farmers and trees in the tropical dry forest in two rural communities of Panama, focusing on the uses and values that small landholders assign to local tree species, both native and exotic.

Farmer’s Perceptions of Silvopastoral System Promotion in Quindío, ColombiabackgroundThe adoption of silvopastoral systems (SPS) reduces pressure on forests and improves ecosystem services. Silvopastoral systems (SPS) are pasture systems in which multipurpose trees, diverse livestock feeds, and other techniques are used to improve productivity and ecosystem services in cattle production areas. In Latin America, conventional livestock production often results in rapid land degradation. SPS provides a longterm solution. This article describes results of a study evaluating farmers perceptions of SPS and, the motivations and disincentives for its adoption in Quindio Province of Colombia Open access copy available |
Evaluation of Andean Alder as a Catalyst for the Recovery of Tropical Cloud Forests in ColombiabackgroundThis study compares the species composition and structural diversity of 30-year-old alder plantations with adjacent, naturally regenerated forests of the same age. The study seeks to determine if alder plantations are an appropriate catalyst for forest regeneration for conserving biological diversity and to determine if the differences between the two forest types are maintained over time.
