Deforestation and Degradation
Targeted habitat restoration can reduce extinction rates in fragmented forestsBackgroundHabitat lost is one of the primary drivers of species extinction. This study examines two highly-fractured ecosystems, the Eastern Arc Mountains of Tanzania and the Atlantic Forest of Brazil, and evaluates the rate at which habitat loss may lead to extinction and thus biodiversity loss. Specifically, the authors use halflife vs. area relationship to determine how long it will take to lose one-half of all tropical bird communities in each habitat. Open access copy available |
Bioremediation of a crude-oil polluted agricultural-soil at Port Harcourt, NigeriaBackgroundSince more than 98% of Nigeria’s current economic support is crude oil, and oil spills are in inevitable and frequent, six treatment sample-cell were tested on the soils of the Niger Delta of Nigeria for crude oil bioremediation. Oil spills cause nitrogen levels to decrease, while increasing carbon content. A decrease in nitrogen and the toxicity of crude oil reduces the growth of heterotrophic bacteria, which utilize petroleum carbon for cell synthesis. Available with subscription or purchase |
Strengthening the national restoration strategyBackgroundIn response to the launch of the Bonn Challenge, El Salvador committed to restoring one million hectares. The country's Ministry of Natural Resources and IUCN applied Restoration Opportunity Assessment Methodology (ROAM) to El Salvador in order to determine and analyze restoration options based on biophysical, social and economic criteria. The paper summarizes the main results generated in the ROAM application. Open access copy available |

Leaders in Action: Achieving Forest Landscape Restoration Through Online LearningBackgroundBetween May 2016 and March 2017, the Environmental Leadership and Training Initiative and IUCN conducted six online courses titled “Forest Landscape Restoration in the Tropics.” These courses were in response to the emerging trend of countries committed to restoring millions of hectares of land via the forest landscape restoration approach, which aims to achieve ecological, economic, and social benefits simultaneously. This paper highlights numerous success stories of individuals who participated in these courses. Open access copy available |
The role of ecological theory and practice in poverty alleviation and environmental conservationBackgroundThis review emphasized the roles and tools of ecologists that would be helpful in poverty alleviation internationally. Specifically, knowledge of sustainable sources of energy, provision of clean water, functional traits of vegetation, and design of agro-forestry systems were cited as examples of knowledge that would be helpful for cross-disciplinary strategies.

Initial performance and reforestation potential of 24 tropical tree species planted across a precipitation gradient in the Republic of PanamaBackgroundPanama has experience significant forest loss due to the conversion of forest lands to agriculture and pasture, causing significant negative effects on ecosystems. Since natural regeneration is slow, the country has recently turned to plantation forestry in order to restore these degraded. Yet, many of these initiatives simply use a few exotic species. This study explores the performance of a range of species, including both native and exotic, in order to better ensure the success and adoption of diversified reforestation strategies.

A local perspective on drivers and measures to slow deforestation in the Andean-Amazonian foothills of ColombiaBackgroundThe Andean-Amazonian foothills in Colombia are highly valuable economically, ecologically, and socially, yet they continue to be under extreme threat of deforestation. This study aims to identify drivers and trends of this deforestation, using a unique methodological approach, seeking to compliment past monitoring studies with on-the-ground information.

Restoration of Degraded Tropical Forest LandscapesBackgroundDeforestation and the declining extent of tropical forests has negatively impacted ecosystem functions, services, and goods and has disproportionately harmed the rural poor of tropical countries. In the wake of deforestation, agricultural development and traditional methods of reforestation (plantations) have largely failed to provide sustainable livelihoods. This review article assesses the strengths and weaknesses of different tropical restoration methods to combat forest degredation and address rural poverty. Open access copy available |
