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.

Local and Regional Environmental Variation Influences the Growth of Tropical Trees in Selection Trials in the Republic of Panama

background

This 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 & Methods

Seedlings 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.

Role of Legumes in Release of Successionally Arrested Grasslands inthe Central Hills of Sri Lanka

Background

Many 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.

Growth characteristics of some native tree species used in silvopastoral systems in the humid lowlands of Costa Rica

Background

Degraded pastures established throughout Central America in the latter 20th C are gradually transitioning to silvopasture or secondary forest. Understanding growth characteristics of trees on these lands is important for proper management.

Evaluation of Reforestation Potential of 83 Tree Species Planted on Imperata cylindrica Dominated Grassland – A case Study from South Kalimantan, Indonesia

background

In this study, 83 tree species (native and exotic) were tested for their growth and survival in species selection trials in South Kalimantan, Indonesia.

Research Goals & Methods

The trees were planted between January 1987 and December 1988 in areas dominated by the exotic grass Imperata cylindrica and weeding was conducted twice a year.

Potential of Agroforestry and Plantation Systems in Indonesia for Carbon Stocks: an Economic Perspective

background

This article discusses the potential for carbon sequestration services in various agroforestry systems in Indonesia. The systems specifically discussed include shade based coffee (Coffea robusta), fruit based coffee, timber based coffee, rambutan (Nephelium lappaceum), pinang (Areca catechu), mango (Mangifera indica), macang (Mangifera spp), candle nut (Aleurites moluccana), durian (Durio zibethinus), duku (Lansium domesticum), and sengon (Paraserianthes falcataria) systems.
