Restoration pathways for rain forest in southwest Sri Lanka: A review of concepts and models

Background

In the last 10 years government policy towards remaining rain forest in Sri Lanka has changed from one that promoted commercial exploitation to one of conservation, recognizing the growing importance of uplands as catchments for water production, biodiversity conservation and other downstream services. This review article discusses recent research on rain forest dynamics of southwest Sri Lanka with the objective of how this knowledge can be used for forest restoration.

Selecting framework tree species for restoring seasonally dry tropical forests in northern Thailand based on field performance

Background

Framework tree species are indigenous forest tree species, planted to complement and accelerate natural regeneration of forest ecosystems and encourage biodiversity recovery, on degraded sites. This study tests the extent to which 37 native forest tree species might act as framework tree species to accelerate recovery of evergreen, seasonal forest in a degraded upper watershed in Doi Suthep-Pui National Park in northern Thailand.

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.

Growth Increments of Indigenous Species Planted in Secondary Forest Area

Background

Appropriate 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.

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.

Forest Regeneration in a Chronosequence of Tropical Abandoned Pastures: Implications for Restoration Ecology

Background

During the mid‐1900s, most of the island of Puerto Rico was deforested, but a shift in the economy from agriculture to small industry beginning in the 1950s resulted in the abandonment of agricultural lands and recovery of secondary forest. This research examines the natural regeneration patterns on these abandoned agricultural lands in four different regions of Puerto Rico.

Impacts of Native Trees on Tropical Soils: A Study in the Atlantic Lowlands of Costa Rica

background

This article describes the results of a study in Costa Rica that compared the soil fertility in a 2.5 year-old plantation of 6 native tree species, grass pasture, and 20 year-old secondary forest.

Rehabilitation of Degraded Tropical Forest Lands

background

This article discusses the options for the rehabilitation of degraded land on high rainfall areas. It suggests that it is both environmentally and economically disadvantageous to let the degraded land remain in an unproductive and rapidly eroding state.

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).

Indigenous Trees in West African Forest Plantations: The Need for Domestication by Clonal Techniques

background

This study evaluates native species tree plantations across West Africa by summarizing existing information on the yield of those plantations, with particular focus on the Cameroon Forest Management and Regeneration Project. It considers the potential for vegetative propagation and clonal selection to increase growth rates and marketability of native species.
