Impacts of payments for environmental services on local development in northern Costa Rica: A fuzzy multi-criteria analysisBackgroundThis paper evaluates the impacts of reforestation projects conducted through Costa Rica's Payment for Environmental Services (PSA) program, which pays landowners for different forest uses. The researchers developed an evaluaton framework that was first based on a set of prinicipals (economic, social, institutional, biological) that were in-term subdivided into different categories. These evaluation criteria were evaluated and weighted through the help of local experts, then used to guide a series of landowner interviews. Open access copy available |
Long-term changes in liana loads and tree dynamics in a Malaysian forestBackgroundIncreasingly lianas are recognized as one of the most important growth form in seasonal tropical forest, yet there has been limited research that has studied the effects in other forests. This study discusses the effect of lianas on tree growth, reproduction, and survivorship in a Southeast Asian Dipterocarp forest. Available with subscription or purchase |

Birds of the Man Made Ecosystems: the PlantationsBackgroundThe authors compare bird diversity in Uttara Kannada, India, comparing intact evergreen and secondary moist deciduous forests to teak, eucaplypts and betelnut plantations with the intent of addressing two questions: what level of diversity can a plantation support and how to species compositions compare to nearby forests?

Growing biodiverse carbon-rich forestsBackgroundCarbon storage and biodiversity has long been viewed as completely separate restoration objectives, resulting in parceling tracts of restoration land for one objective or the other. This study shows that the relationship between plant functional diversity and carbon sequestration rate depends on climate and habitat factors. Knowing this relationship, a restoration site can be managed for both objectives. 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 |
Bridging the great divide: State, civil society, and ‘participatory’ conservation mapping in a resource extraction zoneBackgroundThe author evaluates the outcomes of a participatory and inclusive mapping technique in a mineral extraction zone—the Cordillera Huayhuash—in the Andes of Central Peru. Knowing that land titling is often a source of mistrust and conflict between communities and the government, this technique offers a way to build counter-narratives to the unused territory story often told by state resource management agencies in charge of granting concessions to outside interests.
