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 ...

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 ...

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 ...

Forest & plant canopy analysis - Tools & methods
The range of applications of canopy cover analysis is truly astounding. Canopy analysis derives its usefulness from the vitality of the canopy. Many methods to measure canopy cover have been developed in the last 80 years to meet various objectives. Not surprisingly, there have been several comparisons of the tools in different parts of the world. A general knowledge of canopy cover and the ...

Effect of loblolly pine root pruning on alley cropped herbage production and tree growth
Tillage to disrupt (prune) tree roots is an intensive practice which could improve herbage productivity at the crop–tree interface by reducing competition for water. We compared tillage effects on 9- to 11-yr-old loblolly pine (Pinus taeda L.) growth and herbage yields of annual ryegrass (Lolium multiflorum Lam.) and pearl millet [Pennisetum glaucum (L.) R. Br.] on a fragipan soil in Arkansas. ...

Hardwood tree survival in heavy ground cover on reclaimed land in west Virginia: mowing and ripping effects
Current West Virginia coal mining regulations emphasize reforestation as a preferred postmining land use on surface mined areas. Some mined sites reclaimed to pasture are being converted to forests. In the spring of 2001, we compared the establishment and growth of five hardwood tree species on a reclaimed West Virginaia surface mine with compacted soils and a heavy grass groundcover. We planted ...

How to Get the City to Remove a Tree
Trees, whether they are located on public or private land, can be hazardous. They can also be a nuisance. The question is: what can you do to get your city to remove them? To get your city to remove a tree, you need to inform them of the potential danger, damage, or inconvenience that the tree is likely to cause to the public. Do so by writing to them, calling them, or contacting them via their ...

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 ...
