The Role of Native Species Plantations in Recovery of Understory Woody Diversity in Degraded Pasturelands of Costa RicabackgroundThis study analyzes the understory recruitment success of tropical timber plantations in order to understand biodiversity recovery on degraded lands through the use of fast-growing timber plantations. The study takes place in the Atlantic humid lowlands of Costa Rica. Open access copy available |
The Lembo System: A Model for Agroforestry in Dipterocarp Forest Ecosystems of East KalimantanbackgroundThis article describes the Lembo system of agroforestry, a traditional practice by the Dayak people in East Kalimantan, Indonesia. In Lembo gardens, around 127 species of woody plants are cultivated, and up to 40 different species can be found per 0.25 ha 90% of which are trees. In those gardens, there is also a large diversity of wild, uncultivated plants. Available with subscription or purchase |
Promoting Biodiversity: Advances in Evaluating Native Species for ReforestationbackgroundThis article describes the design of a long-term species screening trial conducted at La Selva Biological Station in Costa Rica. Research Goals & MethodsGrowth and survivability data is presented for 84 species (17 popular exotics used for timber and 67 little-known local species with timber potential) at 3 years of age.

Leaf Litter Decomposition and Mulch Performance from Mixed and Monospecific Plantations of Native Tree Species in Costa RicabackgroundThis research looks at leaf litter decomposition rates and mulch performance of four native tree species in mixed and monospecific plantations at the La Selva Biological Station in Costa Rica. The four species considered were Callophylum brasiliense, Jacaranda copaia, Vochysia guatemalensis, and Strypnodendron microstachyum. The faster the decomposition, the faster the nutrient transfer from the trees into the soils for uptake by other trees or by crops when the leaves are used as mulch.

Daikin Industries Reforestation ProjectBackgroundDaikin Industries Ltd., a Japanese based air-conditioning company, has been partnering with Conservation International (CI) to support the reforestation of a degraded area along the edges of the Gunung Gede Pangrango National Park in Indonesia. The national park, which has some of the little remaining forest area on the island of Java, is a source of water for the cities of Jakarta, Bogor, Tangerang, and Bekasi. Open access copy available |
Soil organic matter dynamics during 80 years of reforestation of tropical pasturesBackgroundLand disturbance affects soil physical and chemical properties. Some properties may be recovered over long periods of reforestation. Mosaic-pattern landscapes with shifting usages over time, common in the mountainous tropics, can reveal dynamic soil properties. This study reports on changes in soil carbon over 80 years of secondary forest growth on abandoned pasture over a chronosequence in Puerto Rico. Open access copy available |
