Restoration and Management Strategies
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 |
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 |
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.

The Sabah Biodiversity Experiment: A Long-Term Test of the Role of Tree Diversity in Restoring Tropical Forest Structure and FunctioningbackgroundThis article details the initial stages of an experiment in Borneo which aims to study the relationship between tree diversity and lowland dipterocarp rainforest functioning during restoration after selective logging.

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.

Restoration of degraded forest land in Thailand: the case of Khao KhoBackgroundThis chapter discusses the deforestation of Khao Kho district, situated in Thailand’s central highlands, in the 1970s and restoration efforts in the 1990s. Over 75% of the district was forested until 1968, when as a counterinsurgency strategy the Royal Thai Army began to build roads, deforest the district and encourage agricultural settlement in this heretofore intact forest. Deforestation and maize cultivation on these steep hillsides, often with already-poor soil quality degraded in situ, led to rapid degradation with farming untenable by 1990. A UNDP-funded reforestation project – managed by the Army – was initiated in 1990. Open access copy available |
