Evaluation of regeneration of Shorea robusta forests under joint forest management in West Bengal, India
West Midnapore, West Bengal, is one of the pioneering localities for joint forest management experiments in India, imparting a momentum to such a large programme on community forestry. Thus, a review and understanding of the success and failures would help a long way in finetuning an already developed programme, particularly from the ecological point of view. Midnapore division has indicated ...

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 ...

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 ...

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 ...

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 ...

Evaluating the role of vegetation on the ventilation performance in isolated deep street canyons
Vegetation is generally considered as an essential component for a sustainable city as it helps improve its microclimate environment and reduce greenhouse gases emissions. However, there is some evidence suggesting that adverse effects may be caused by tree–planting in shallow urban street canyons. Accordingly, we intended to investigate whether similar observations are found for different canyon ...

A generic approach in estimating vegetation density for hydrodynamic roughness parameterization using high density airborne laser scanning data
Vegetation density is among the important parameters required for determination of hydrodynamic roughness over vegetated areas. High density airborne light detection and ranging (LiDAR) data offer several potentials to improve estimation of vegetation density. Available methods in estimating vegetation density based on regression models did not take into account understorey vegetation and were ...

Climate and Economic Benefits of Agroforestry Systems
Introduction Agriculture is well known as a significant contributor to global greenhouse gas emissions, but emerging practices in land management have the potential to curtail these emissions and reverse much of the ecological and climate harm caused by overly intensive systems. One such practice, cultivation and conservation of trees in agricultural practices, or agroforestry, is an important ...

Tree Root Imaging at a Historical Site: In-Depth Assessment of Tree No. 1 – the Copper Beech Tree - Case Study
Background: A mature Copper Beech tree is located in a prominent position at a historical site in the United Kingdom that is known for its archaeological significance and is a major tourist attraction. The tree is of significant amenity value in this public place. It is also very close to a proposed development and is likely to be impacted by the construction of planned new structures. Its ...

Why Our Buildings Should Be Made From Wood
If done correctly, using wood for buildings would have a number of environmental benefits without loss of biodiversity or carbon storage capacity. Although it may seem counterintuitive, it would be better if we built buildings from wood than from concrete, brick, aluminium and steel. We use millions of tons of these modern materials every year. They have many valuable properties, but are ...

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 ...

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 ...

Eight nonnative plants in western Oregon forests: Associations with environment and management
Nonnative plants have tremendous ecological and economic impacts on plant communities globally, but comprehensive data on the distribution and ecological relationships of individual species is often scarce or nonexistent. The objective of this study was to assess the influence of vegetation type, climate, topography, and management history on the distribution and abundance of eight selected ...

Intro to precision forestry
Never before has the interest in preserving natural forests and efficient management of plantations been as great as the present. Demand for wood products is increasing. On the other hand, it is also evident that the remaining forests have to be protected to maintain our quality of life—the very air we breathe depends on them. Therefore, precision management, which has been successfully ...

Relative Importance of Environmental Stress and Herbivory in Reducing Litter Fall in a Semiarid Woodland
We examined the impact of soil stress (low water and nutrient availabilities) and two keystone insect herbivores on pinyon pine (Pinus edulis) needle litterfall. We compared trees growing on two distinct soil types: volcanic cinders, which exhibit pronounced water and nutrient limitation, and sandy-loam soils, which have higher water-storage capacity and nutrient availability. Using two long-term ...
