Restoring abandoned pasture land with native tree species in Costa Rica: Effects of exotic grass competition and lightBackgroundUnderstanding the early establishment requirements and performance of tropical tree seedlings is essential to ensuring the success of restoration plantings. This study characterizes growth and light requirements of six common neotropical tree species: Pseudosamanea guachapele (Fabaceae), Tabebuia impetiginosa (Bignoniaceae), Ceiba pentandra (Bombacaceae), Pachira quinata (Bombacaceae), Dalbergia retusa (Fabaceae), and Tabebuia rosea (Bignoniaceae).

New Options for Land Rehabilitation and Landscape Ecology in Southeast Asia by "Rainforestation Farming"backgroundThe authors describe a methodology for reforestation called "Rainforestation Farming" developed in the Philippines in the 1990s to restore forest cover on degraded lands covered with Imperata cylindrica grass in the Visayas region Available with subscription or purchase |
Monitoring of Black Mangrove Restoration with Nursery-Reared Seedlings on an Arid Coastal LagoonbackgroundThis paper describes a reforestation experiment with black mangrove (Avicennia germinans) in an arid mangrove forest of Baja California Sur, Mexico. In arid mangrove systems, natural regeneration and small-scale reforestation are not adequate to restore mangrove forests, as they may be in the humid tropics. Thus, alternative nursery techniques for arid mangroves must be developed. Available with subscription or purchase |
Cattle and Weedy Shrubs as Restoration Tools of Tropical Montane RainforestbackgroundIn abandoned Latin American pastures, grasses often inhibit the establishment of woody species. This study tests the effect of cattle grazing on woody and herbaceous vegetation establishment in pastures of P. clandestinum and M. minutiflora. Available with subscription or purchase |
The Structure and Composition of a Tropical Dry Forest Landscape After Land Clearance; Azuero Peninsula, PanamabackgroundThis article describes natural regeneration that has occured in five different habitat types in the Azuero Peninsula of Panama. These habitat types include active pasture, 2-yr abandoned pasture, 5-yr abandoned pasture, forest riparian zones, and a secondary forest fragment. This region is characterized by agricultural and cattle ranching landcapes in areas that previously were tropical dry forest (1700 mm rainfall per year) until the mid-20th century and have recently been undergoing rapid turnover in land ownership.

The Role of Animal Seed Dispersal in Accelerating Native Forest Regeneration on Degraded Tropical LandsbackgroundThis article reviews the role of seed-dispersal in forest regeneration. In natural forest, species with animal-dispersed species tend to predominated in both early and mid-stages of succession, while wind-dispersed species tend to be vines and canopy species. The implications of wind versus animal seed dispersal are briefly summarized. Available with subscription or purchase |
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.

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 |
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.

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 |
