Ectomycorrhizal Colonization and Seedling Growth of Shorea (Dipterocarpaceae) Species in Simulated Shade Environments of a Sri Lankan Rain ForestBackgroundThis study examines how the degree of ectomycorrhizal (EM) colonization of potted Shorea spp. is associated with the amount and quality of daily photosynthetic photon flux density (PFD).

Net Primary Productivity of Two Mangrove Forest Stands on the Northwestern Coast of Sri LankaBackgroundThis article compares the net primary production of an estuarine mangrove stand to an island fringing stand in Dutch Bay in northwestern Sri Lanka. Research Goals & MethodsNet above-ground primary productivity was measured by monitoring litterfall and above-ground biomass increment between 1985 and 1987. Available with subscription or purchase |
Structural Properties of Two Types of Mangrove Stands on the Northwestern Coast of Sri LankabackgroundThis article compares the structural diversity of six mangrove stands of both estuarine and island-fringing types in Puttalam lagoon and Dutch Bay in northwestern Sri Lanka. Research Goals & MethodsUsing belt transects, the authors measured floristic composition, tree height and leaf-area index and calculated density, basal area and mean stand diameter. Standing above-ground biomass was also measured and compared to dbh using destructive sampling methods. 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.

Monitoring Mangrove Forest Dynamics of the Sundarbans in Bangladesh and India using Multi-Temporal Satellite Data from 1973 to 2000BackgroundIn the Sundurbans of India and Bangladesh, the authors measured the extent and condition of the mangrove forest at three intervals using GeoCover datasets (Landsat MSS, TM, ETM+) with the goal of assessing the current extent of the remaining forest, measuring change in the extent of the forest in different time periods, and identifying areas of intensive deforestation or degradation and changes in patterns of canopy density.

Afforestation for Reclaiming Degraded Village Common Land: A Case StudybackgroundIn India, population growth and agriculture put a strain on natural resources, often resulting in "wastelands" where the soil is no longer productive - often either affected by either salt or alkilinity. Using soil amendments to restore these lands to productivity can be cost-prohibitive for the small villages that own these lands. Afforestation is one possible method for restoring the health of these in a cost-effective and scalable way. Available with subscription or purchase |
Integrating National Forestry Initiatives in India with International Climate Change PolicybackgroundThis study reviews forest policies in India (eg. 1988 Forest Policy, 1990 Joint Forest Management, and 2006 Recognition of Forest Rights) and their impacts to assess how they can complement and inform international climate change mitigation instruments. It also seeks to determine how communities can sustain their system of forest management and retain/obtain rights to land and resources under these instruments.

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.

Reforestation with the Native Tree Alnus acuminata: Effects on Phytodiversity and Species Richness in an Upper Montane Rain Forest Area of ColombiaBackgroundThis study takes place in the western cordillera in Colombia (Quindio). Upper montane forest is dominated by large Weinmannia (Alnus acuminata) plantations established from 1977-1978 on abandoned agricultural and grazing land (for erosion control), and secondary forest fragments that naturally colonized abandoned agricultural areas.

Evaluation of Native Tree Species for the Rehabilitation of Deforested Areas in a Mexican Cloud ForestbackgroundThis study examines the survival of four native tree species used in mixed-experimental plantations in the tropical montane forest of Veracruz, Mexico (1300-1900m). Tropical montane covers only 1% of land surface in Mexico but contains ~ 10% of all flowering plants. In Veracruz, forest fragments occupy on 10% of the oringinal forest cover.
