Early Growth of Native and Exotic Trees Planted on Degraded Tropical PasturebackgroundThis study describes the potential of two exotic and five native tree species to restore degraded land in Costa Rica. Research Goals & MethodsThirty blocks were established over 25 hectares of abandoned cattle pasture and tree height was measured at 3 and 7 years and tree survival was measured after 7 years.

The Apparent Paradox of Reestablishing Species Richness on Degraded Lands with Tree MonoculturesbackgroundThis article discusses the use of tropical tree plantations as an approach to rehabilitation of degraded landscapes. For extremely degraded sites, the use of plantations may provide the proper shade, microclimate and protection for other species to colonize the understory. Research on the use of plantations in restoration is discussed, with examples primarily from Puerto Rico. Open access copy available |
Growth and effects of thinning of mixed and pure plantations with native trees in humid tropical Costa RicaBackgroundAs reforestation with native tree species gains in popularity, more information about proper management is needed. This study examines the growth and responses to thinning of ten native species in mixed and pure-species plantations in the Caribbean Lowlands of Costa Rica. Open access copy available |
Pure and Mixed Forest Plantations with Native Species of the Dry Tropics of Costa Rica: A Comparison of Growth and ProductivitybackgroundThis research monitored the growth and survival of 13 natives species in pure and mixed-species plantations, and compared the results to measurements of T. grandis, an exotic species commonly planted in the area.

Studies on the Seed Biology of 100 Native Species of Trees in a Seasonal Moist Tropical Forest, Panama, Central AmericaBackgroundSince 1998, the Panama Canal Watershed has experienced a decline in forest cover. The watershed ensures a functioning canal, thus there has been a significant investment in resources to reforest and restore the region. While these projects have focused primarily on native species, there has been issues with seed-handling. Available with subscription or purchase |
How Successful is Tree growing for Smallholders in the Amazon?backgroundThis study compares donor-driven and smallholder-initiated tree growing projects in the Amazon to assess outcomes such as tree survival, commercialization success, and environmental benefits of two different approaches to tree planting. Such research is important for understanding the limitations of both smallholder and donor-driven tree growing for reforestation, and for improving production of forest products outside of natural forests. The study also emphasizes the importance of capturing local knowledge. Open access copy available |
Landscape Rehabilitation of Degraded Tropical Forest Ecosystems: Case Study of the CIFOR/Japan Project in Indonesia and PerubackgroundThe CIFOR/Japan project on tropical forest restoration involves three principal components: 1) evaluation of logging impacts on forest systems, 2) development of methods for the restoration of logged and degraded forests, and 3) development of silvicultural practices for degraded forests.

Forest Management Practices in the Bayano Region of Panama: Cultural VariationsbackgroundThis paper examines differences in forest exploitation between indigenous groups and colonists along an agricultural frontier in Panama and focuses on differences in forest use, economic base, and management practices. Research Goals & MethodsThe author compares total annual income, timber harvest volume and tree planting efforts per household in 5 indigenous villages and 3 colonist villages.

Fire in the Seasonal Semideciduous Forest: Impact and Regeneration at Forest EdgesbackgroundThis study looks at a fragment of semi-deciduous forest in Brazil to determine the effects of fire on vegetation at varying distances from the fragment’s edge, as well as the recovery of forest structure and species diversity after fire.

Forest Regeneration in a Chronosequence of Tropical Abandoned Pastures: Implications for Restoration EcologyBackgroundDuring 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. Available with subscription or purchase |
