Carbon stock in Kolli forests, Eastern Ghats (India) with emphasis on aboveground biomass, litter, woody debris and soils

background

Carbon estimates for India’s forests are inadequate because they are largely based on secondary data. While actual carbon estimates exist in some locales, a nationwide carbon inventory is needed. This study contributes an evaluation of above- and belowground biomass and carbon stocks in the Kolli Hills of the Eastern Ghats, Tamilnadu.

Variation in Canopy Structure, Light and Soil Nutrition Across Elevation of a Sri Lankan Tropical Rain Forest

Background

This study aims to examine differences in resource availability across elevation and geology in mixed dipterocarp forest by measuring light, soil nutrition and soil water availability in relation to forest structure in southwest Sri Lanka.

Structural Properties of Two Types of Mangrove Stands on the Northwestern Coast of Sri Lanka

background

This 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 & Methods

Using 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.

A review of the floral composition and distribution of mangroves in Sri Lanka

Background

The article reviews literature on the numbers and distributions of Sri Lankan mangrove species and highlights the causes of overestimation. It also attempts to provide an accurate count based on standardized fieldwork over a 4-year period along the coast between Palatupana and Puttalam, Sri Lanka. The authors name some examples of mischaracterized or misidentified species from previous studies and address the importance of clearly defining the terms for mangroves.

Ectomycorrhizal Colonization and Seedling Growth of Shorea (Dipterocarpaceae) Species in Simulated Shade Environments of a Sri Lankan Rain Forest

Background

This 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).

Spatial Interpolation of Carbon Stock: A Case Study from the Western Ghats Biodiversity Hotspot, India

Background

This study in the Anamalai Hills of the Western Ghats estimates the biomass and carbon stock of major tropical forest types in India and attempts to identify suitable interpolation techniques to map carbon stock.

Growth, biomass, carbon storage and nutrient distribution in Gmelina arborea stands on red lateritic soils in central India

Background

Large-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.

Carbon sequestration versus bioenergy: A case study from South India exploring the relative land-use efficiency of two options for climate change mitigation

background

This study explores avenues to meet increased rural electricity demand with carbon emissions mitigation. The study compares the option of energy derived from gasification of biomass from forest plantations to energy derived from fossil fuels, with forest plantations used as a carbon sink.The case study uses power demand, land requirements, and management approaches for Hosahalli village, Karnataka, pop. 218.

Forest conservation, afforestation, and reforestation in India: Implications for forest carbon stocks

Background

Considering India’s goal to have 1/3 of their land area forested by 2012, this article assesses the implications of past and current forest conservation and regeneration policies and carbon stock programs.

REDD+ Readiness Implications for Sri Lanka in Terms of Reducing Deforestation

Background

This study constructs a historical reference level of emissions from deforestation in Sri Lanka using available forest inventory data and in situ carbon density data. It also attempts to identify drivers of deforestation in Sri Lanka and to estimate the opportunity cost and possible climate benefits of forest conservation.
