Biomass estimation equations for tropical deciduous and evergreen forests
In this study, linear and non-linear regression equations were developed to estimate biomass of tropical forests along with estimates of goodness of fit and percentage of errors. Basal area, average height of trees and tree density data from published reports, were used to develop equations to estimate biomass of deciduous and evergreen forests. Basal area and height of trees are found to give ...

Building an index of site suitability for forest residue removal
Evelyne Thiffault said she would address ecological issues, although she emphasized that she believes “producing bioenergy from forest biomass is a great idea.” Forest biomass has an ecological value that must be considered, she said. If forest residues are removed to produce bioenergy, then the forest system is deprived of carbon and nutrients, and “you will impact the forest ecosystem.” ...

Wood innovations grants provide funding for biomass projects
The U.S. Department of Agriculture (USDA), in partnership with the U.S. Forest Service, has announced the recipients of the 2015 Wood Innovations Grants. More than 40 projects were awarded over $9 million to expand and accelerate wood energy and wood product markets. The $9 million will leverage private investments from partners, resulting in a total of $31 million distributed to grant winners ...

Herb layer productivity under different light gaps in the forests of Western Ghats of Karnataka, India
A productivity estimation of tree, shrub and herb layer biomass was undertaken in Uttara Kannada, a Western Ghats district in Karnataka in differentially managed forests. In addition to biomass, light gap in these sample sites was also estimated to understand the relationship between the light interception pattern at different canopy layers and their productivity. The studies indicate that tree ...

Regeneration of teak forests under joint forest management in Gujarat
In order to understand the impact of JFM in Gujarat, a study was conducted in three divisions viz., Baria, Rajpipala and Sabarkantha covering 24 villages. Vegetation parameters such as species richness, density of trees, basal areas, Shanon Weiner's diversity index, woody biomass and MAI were observed and compared with control plots in a non-JFM village. Stem density, species richness, species ...

Forest fuels reductions and biomass to Energy: Parallel opportunities for public benefit
Larry Mason has investigated the links between forest health problems and biomass to energy. “There are some real disconnects,” he said. Washington’s Inland West is “at a high, unprecedented risk of a catastrophic crown fire,”unless fuel loads are reduced. The rhetorical problem with reducing these fuel loads is that the cost of removing small diameter fuels may exceed their market value. “But ...

Community forestry initiatives in Southeast Asia: a review of ecological impacts
Studies in South and Southeast Asia were reviewed to understand the impact of community forestry initiatives in recent times on the ecology, with respect to species richness, biomass enhancement and forest regeneration. The findings from diverse ecological regions of South and Southeast Asia have demonstrated that community forestry has resulted in significant increase in plant diversity and ...

Molecular-scale characterization of hot-water-extractable organic matter in organic horizons of a forest soil
Hot-water-extractable organic matter (HWEOM) has been shown to be highly correlated with microbial biomass in forest soils. We conducted elemental and 13C solid-state nuclear magnetic resonance spectroscopic analyses to assess the composition and structural chemistry of HWEOM and its variations with soil depth within O horizons in a forest site in New Hampshire. The HWEOM fraction exhibited a ...

Biomass harvesting: how forest thinning can help prevent wildfires
Every year, wildfires plague the nation. Once there’s an ignition source, dry foliage in country areas can quickly go up in flames, spreading through woodlands or grasslands quickly. While some wildfires can be small, others can be devastating and blaze through thousands of acres. While there’s no way to predict where wildfires may start, there are ways to minimize the damage of ...

Forest protection and regeneration under joint forest planning and management in Eastern Plains and Western Ghats of Karnataka, India
Joint forest management in Karnataka, India was initiated in the Western Ghats and Eastern Plains. In Western Ghats, multispecies model was adopted, while in Eastern Plains 13 silvicultural models were adopted, of which assisted natural regeneration accounted for 43% of the plantation area that had rootstock. In addition, pre-JFPM plantations raised under social forestry were also included under ...

Environmental impacts of community-based forest management in the Philippines
Community-based forest management (CBFM) is a major strategy in managing forest lands in the Philippines. Forest and land management activities implemented in CBFM project sites include management of tropical forests (enrichment planting, timber stand improvement or TSI and limited harvesting), rehabilitation of degraded lands (reforestation, assisted natural regeneration (ANR)) and agroforestry. ...

Reviving the degraded forests of Andhra Pradesh, India: an effort through joint forest management
Joint forest management in Andhra Pradesh was initiated to restore degraded forests and support livelihoods of forests dependents. Vegetation development in 20 JFM villages was assessed. Stem density ranged up to 321 trees/ha. Number of cut stems/ha varied from 49–92 indicating tree removals. Tree species were over 50 in Ghats, 40 in sub plains and 30 in plains indicating biodiversity ...

An ecological assessment of greening of Aravali mountain range through joint forest management in Rajasthan, India
Rajasthan is one of the largest Indian states with about 9% of its total geographical area covered with forest. Large area of the state is covered with desert, has one of the highest livestock populations and therefore has severe shortage of biomass for local use. The community forestry initiative in this state has resulted in significant regeneration, enhanced biomass and enhanced tree cover in ...

Sub-critical water as a green solvent for production of valuable materials from agricultural waste biomass: A review of recent work
Agricultural waste biomass generated from agricultural production and food processing industry are abundant, such as durian peel, mango peel, corn straw, rice bran, corn shell, potato peel and many more. Due to low commercial value, these wastes are disposed in landfill, which if not managed properly may cause environmental problems. Currently, environmental laws and regulations pertaining to ...
