Forest Plantations
Degraded Lands Worth Protecting: the Biological Importance of Southeast Asia's Repeatedly Logged Forests.BackgroundThe study examines the impacts of second logging cycles on biodiversity by comparing species richness, species composition and population-level responses of birds and dung beetle species across unlogged forest, first rotation forest, and second rotation forest in Sabah, Malaysia. Research Goals & MethodsThe authors sample 18 sites, 6 for each forest type, over a two year period. They use point count and mist net censuses for bird species and pitfall traps to count dung beetles. Open access copy available |
Seed rain under tree islands planted to restore degraded lands in a tropical agricultural landscapeBackgroundPlanting native tree seedlings is the predominant restoration strategy for accelerating forest succession on degraded lands. However, planting tree “islands” is less costly and labor intensive than establishing larger plantations and simulates the nucleation process of succession. Tree islands can attract seed dispersers to gradually spread restoration patterns from the islands. Restoration design can be informed by assessing the effect of potential planting arrangements on seed dispersal by birds and bats and determining the influence of surrounding forest cover.

Can tropical farmers reconcile subsistence needs with forest conservation?backgroundDespite efforts to protect tropical rainforests through various policy initiatives, forests continue to face pressure from smallholders' subsistence needs, especially in montane regions. This paper proposes a means to turn abandoned montane pastoral land into productive agroforestry land as a viable alternative to further encroachment on existing forests.

Adaptabilidad y crecimiento de especies nativas en areas en recuperacion del noroeste de la provincia de Misiones (Adaptability and growth of native species in recovery areas in the northwest of the province of Misiones)BackgroundThis study takes place in the Argentinean province of Misiones, where there was a high level of land degradation and strong need for reforestation to restore productivity to the landscape.

Growth, biomass, carbon storage and nutrient distribution in Gmelina arborea stands on red lateritic soils in central IndiaBackgroundLarge-scale plantations are being established on degraded lands in India to restore the productivity of these soils and landscapes and to sequester atmospheric carbon. Gmelina arborea is a fast-growing indigenous tree used for timber, fuelwood, pulp and fodder already in use in reforestation projects. However, its growth and biomass production has been inadequately studied, particularly in the poor red laterite soils that dominate degraded landscapes. Available with subscription or purchase |
The Rain–Runoff Response of Tropical Humid Forest Ecosystems to Use and Reforestation in the Western Ghats of IndiaBackgroundThis study expands on a previous study in the Western Ghats of India (Uttar Kannada, Karnataka State), that suggested a greater occurrence of infiltration-excess and potentially higher streamflow in degraded and reforested areas. Analyzing rainfall–streamflow data, the authors attempt to determine the impacts of different land cover types on stream discharge hydrograph components (viz, total flow, quickflow and delayed flow), the dominant stormflow pathways, and the impact of reforestation efforts on these processes.

The Impact of Forest Use and Reforestation on Soil Hydraulic Conductivity in the Western Ghats of India: Implications for Surface and Sub-Surface HydrologybackgroundThis article presents research on the surface and sub-surface permeability of degraded and restored forests and their dominant stormflow pathways in the humid tropics of Uttar Kannada district, Karnataka, India. The authors attempt to determine to what extent field saturated hydraulic conductivity (K*) isaltered due to long-term forest degradation as compared to other studies in the humid tropics. They quantify changes in permeability following forestation of plantations and degraded landscapes and investigate the likely effect of wet-season conditions and the implications this has for predicting hydrologic consequences of forest degradation.

Mahogany and Kadam planting farmers in South Kalimantan: the link between Silvicultural activity and stand qualityBackgroundIncentive structures in Indonesia have promoted forest plantations conducted and managed in partnership with local farmers. This paper examines the relationship between farmers’ socio-economic characteristics, silvicultural activity and the quality of their mahogany (Swietenia macrophylla) and kadam (Anthocephalus/Neolamarkia cadamba) plantation stands in two independent case study villages in South Kalimantan Province, Indonesia.

Migratory Bird Species in Young Tropical Forest Restoration Sites: Effects of Vegetation Height, Planting Design, and SeasonbackgroundThis study examines the difference in habitat preference of four migratory birds in restored forests in southern Costa Rica. Open access copy available |
China's sloping land conversion program: Institutional innovation or business as usual?BackgroundChina’s Sloping Land Conversion Program (SLCP) is the largest land retirement program in the developing world, having the goal of converting 14.67 million hectares of cropland to forests by 2010, primarily targeting high-slope and marginal lands. The program is being implemented in more than 2000 counties across 25 provinces in China and affects tens of millions of rural households using PES models to promote afforestation.
