Screening Trial of 14 Tropical Hardwoods with an Emphasis on Species Native to Costa Rica: Fourth Year ResultsBackgroundA lack of silvicultural information on native timber species in the tropics has contributed to the propogation of fast-growing exotic tree species in reforestation efforts. The plantations evaluated at the La Selva Biological Station in Costa Rica were considered marginal lands with low input of forest maintenance, reflecting the conditions of many lands that farmers would use for reforestation.

Genetic Consequences of Tropical Second-Growth Forest RegenerationBackgroundThis article is an examination of the genetic impacts of old-growth deforestation among 24 year-old second-growth Iriartea deltoidea, a canopy palm, in a lowland Costa Rican forest. Iriartea is widely distributed throughout neotropical rainforests and displays a diverse range of size classes in mature forests. This species recolonizes second-growth forests with newly generated seeds, which are dispersed by birds and mammals. Open access copy available |

Impact of Forest Management on Insect Abundance and Damage in a Lowland Tropical Forest in Southern CameroonBackgroundA burgeoning timber industry in Cameroon, which became the fifth largest producer of timber in the world in the 1990’s, led to unsustainably high deforestation rates and high demand for forest regeneration interventions. Research in the Mbalmayo Forest Reserve in southern Cameroon has compared different silvicultural techniques for forest regeneration including complete and partial clearance methods.

Nitrogen-fixing trees inhibit growth of regenerating Costa Rican rainforestsBACKGROUNDNitrogen fixing plants are the primary source of nitrogen in forests, and it is expected that more nitrogen fixers will bring in faster growth. Hence this study conducted, in a humid tropical rainforest North- East Costa Rica, challenged this notion. The area of study had similar dominant species, with P. macroloba being the most dominant Nitrogen fixer. Open access copy available |
Environment and landscape rather than planting design are the drivers of success in long‐term restoration of riparian Atlantic forestIntroductionWhile identifying factors that contribute to restoration is difficult, it is ultimately critical in order to ensure the long-term sustainability and resilience of the restored landscape.

Forest plantations and climate change discourses: New powers of ‘green’ grabbing in CambodiaBackgroundAvailable with subscription or purchase |
Carbon colonialism and the new land grab: Plantation forestry in Uganda and its livelihood impactBackgroundThere has been a global increase in private sector investments towards activities plantations for clean fuel or climate change mitigation that are justified on the basis of their environmentally beneficial outcomes. This paper examines the discourses and mechanisms that enable the greater privatization of land and other resources using green development as a justification.

Adopt a carbon tax to protect tropical forestsBackgroundInternational investments in natural climate solutions such as conservation, restoration and land management remain low in many tropical countries. The authors point to research which shows that only 3% of global finance for climate change mitigation went towards natural climate solutions in 2017-18. They recommend constituting a national level carbon tax on fossil fuel companies to generate revenue to fund natural climate solutions. Open access copy available |

Density-dependent reproductive success among sympatric dipterocarps during a major mast fruiting eventBackgroundMasting or mast fruiting is the annual synchronous production of many seeds by a plant species. Masting is an important reproductive strategy that depends on the intensity of flowering and fruiting, as well as the seeds’ ability to survive herbivory and competition with other seeds. Southeast Asia, many tree species (particularly Dipterocarps) are known to synchronize their masting events and therefore, community-wide seed density is an important factor predicting successful reproduction.

Tropical fruit production depends on wild insect communities: bees and lychees in ThailandBackgroundMost of the agricultural crops around the world depend on wild animal/insect pollination. Insect pollination is the most common in tropical regions, and is something that tropical tree fruits such as the native Asian lychee (Litchi chinensis). The roles of wild insects on lychee production in northern Thailand has not yet been evaluated. Available with subscription or purchase |
Tree Canopy Management Affects Dynamics of Herbaceous Vegetation and Soil Moisture in Silvopasture Systems Using Arboreal LegumesBackgroundIt is important to understand how herbaceous and arboreal species interact with each other, specifically how shade effects understory plants. Silvopasture functions best when both strata of the forest are thriving. Silvopasture is impacted by species chosen, spacing of tree plantings, and other management practices. Tree legume species such as Gliricidia sepium and Mimosa caesalpiniifolia hold a potential value for commercial use while also fixing soil nitrogen in the soil. Open access copy available |
National parks and conservation concessions: a comparison between mammal populations in two types of tropical protected areas in Ucayali, PeruBackgroundPeru holds the second largest portion of the Amazon rainforest and is threatened by illegal logging and crop cultivation, as well as mining and other activities. Protected areas are one method of forest conservation, which can exist as conservation concessions. These areas of land granted for protection and rehabilitation area vital to maintaining the health and distribution of the forest. Biodiversity is understudied in many of these regions, especially about terrestrial mammals. Open access copy available |
