This study compares the data available from different satellites having different spatial resolutions to estimate the timber volume. The study comprises mainly the stratification of forest from the input of classified satellite data, measurement of timber volume in the field, extraction of the pixel information for the plots, preparation of a continuous volume map and its comparison among diffe...

Introduction The availability of timber has become an issue across tbc South as supplies from other regions are constrained and as demand for timber continues to grow. Whiie any individual state or landowner will have a small impact on national timber supphes, the avaibbiliv of local timber will have a profound (SERTS), harvest, inventory and growth trc.nds are developed for both nonindustrial ...

Logging has been a much maligned feature of frontier development in the Amazon. Most discussions ignore the fact that logging can be part of a renewable, environmentally benign, and broadly equitable economic activity in these remote places. We estimate there to be some 4.5 +/- 1.35 billion m(3) of commercial timber volume in the Brazilian Amazon today, of which 1.2 billion m(3) is currently pr...

Aggregate timber supply by ownership was investigated for a small region by applying stand-level harvest choice models to a representative sample of stands and then aggregating to regional totals using the area-frame of the forest survey. Timber harvest choices were estimated as probit models for three ownership categories in coastal plain southern pine stands of North Carolina using individual...

In the last two decades, many firms in the U.S. forest products industry have either divested their timberlands to timber investment management organizations (TIMOs) and conservation organizations or converted their corporate structures from C corporations to real estate investment trusts (REITs). All landowners sold smaller timberland tracts for nonforestry uses. Reduced timber supplies from c...

The study was carried out in four community forest user groups (CFUGs) of Sindhupalchok district of Nepal with a view to find out the consumption pattern of forest products especially timber and fuelwood from the community forests (CFs). A set of structured questionnaires was used to collect data from the respondents of the selected CFUGs. Four CFUGs were randomly selected from among those meet...

This paper presents the state-of-the-art of using non-destructive testing (NDT) methods based on elastic waves for the condition assessment of structural timber. Two very promising approaches based on the propagation and reflection of elastic waves are described. While the first approach uses ultrasonic echoes for the testing of wooden building elements, the second approach uses guided waves (G...

Quick reactions to customers’ needs, i.e. customized production, has been a common aim of the forest industries in Finland during the past decade. At first, it was thought to be suitable only for small and medium-sized industries, but nowadays large corporations have also developed their processes to make them increasingly customerorientated. Major development projects have been launched recent...

The angle between helical windings of microfibrils in the secondary cell wall of fibers and the long axis is called microfibril angle (MFA). Stiffness of wood depends on variations in the MFA. The large MFA shows low stiffness, which is found in juvenile wood and this character make threes vulnerable to high winds breaking. Timber containing a high proportion of juvenile wood is unsuitable for ...

Migration presents a trade-off for individuals between the potential fitness benefits of reaching high-quality habitat vs. the potential costs of migration. Within an information-theoretic framework, we examined the costs of migration for adult wood frogs (Rana sylvatica) in response to timber harvest and annual weather conditions using Cox proportional-hazard estimates of survival. In 2004 pri...
