Secondary & Degraded Forest Restoration
Variation in the population structure between a natural and a human-modified forest for a pioneer tropical tree species not restricted to large gapsBackgroundThe study evaluates the distribution of Cyperus floribundus (a long-lived pioneer tree specie) individuals in the gaps and compared the plant density between a primary and an early successional forest to understand the pioneer plant distribution and niche preference under the variable environmental and biotic conditions generated by natural or anthropogenic disturbances.

Dominant species' resprout biomass dynamics after cutting in the Sudanian savanna-woodlands of West Africa: long term effects of annual early fire and grazingBackgroundGiven widespread anthropogenic disturbance and land degradation across the Sudanian savanna-woodlands of West Africa, these researchers examined the impacts of early annual fire and grazing on 6 dominant plant species in terms of: shoot mortality, height and girth. Though rather unoriginally, they hypothesized that forest biomass reconstitution is affected by disturbances such as fire and grazing. Open access copy available |
Using artificial canopy gaps to restore Puerto Rican Parrot (Amazona vittata) habitat in tropical timber plantationsBackgroundThis study tests whether or not man-made canopy gaps can restore native tree diversity as food sources for the endagered Puerto Rican Parrot (Amazona vittata). The site is located within a non-native blue mahoe (Hibiscus elatus) plantation in the Río Abajo forest in central Puerto Rico, where the researchers planted native species in assisted natural regeneration. The gaps were created in 20m x 20m plots by girdling and applying herbicide on non-native trees and by clearing leaf litter and vegetation, creating space for planted and naturally established advance regeneration seedlings.

Direct seeding to restore rainforest species: Microsite effects on the early establishment and growth of rainforest tree seedlings on degraded land in the wet tropics of AustraliaBackgroundIn Queensland, Australia, three degraded sites (a high elevation site, mid elevation site and low elevation site) that were dominated by non-native grass were studied. The study looked at how six different methods of sowing affected the establishment and growth of small and large seeds, as well as how it affected weeds growth and re-establishment. Before the sowing treatments were conducted, the weeds, since it often outcompetes seeds/seedlings, were removed using herbicides. The sowing treatments created microsites that either consisted of the seeds being buried beneath the soil or placed above the soil. Available with subscription or purchase |
Conserving Tropical Tree Diversity and Forest Structure: The Value of Small Rainforest Patches in Moderately-Managed LandscapesBackgroundDue to deforestation and degradation in rainforests, there has been an increase in small forest patches yet there is limited understanding of this structures contribution to biodiversity and ecosystem services. The authors of this study attempt to answer this question through studying a a moderately managed landscape in the tropics of Mexic Open access copy available |

Factors influencing community participation in mangroves restoration: A contingent valuation analysisBackgroundThis paper analyzes the willingness of a household to participate and pay for the benefits of a mangrove restoration program in the West Coast of India. In the second half of the twentieth century, this region has been threatened by shrimp cultivation, industrial development and hydroelectric projects, which overall made mangroves recede substantially.

Burning biodiversity: Fuelwood harvesting causes forest degradation in human-dominated tropical landscapesBackgroundIn the Northeastern Brazilian Atlantic Forest (BAF), extremely dense populations of poor, rural villages create chronic disturbances within the already heavily fragment Atlantic forest in favor of gathering hardwood fuel supplies. This hardwood is self-gathered without management techniques and burned inefficiently, and is driven by poverty, proximity to forest fragments, human labour availability, and lack of alternative energy sources. One of the most biodiverse, endemic, and endangered regions on the planet, this research seeks to study the impact of rural fuelwood development in the northeastern BAF. Open access copy available |
