Please cite this article in press as: Millington, J songbirds and timber production. Forest Ecol. The structure of forest stands is an important determinant of habitat use by songbirds, including species of conservation concern. In this paper, we investigate the combined long-term impacts of variable tree regeneration and timber management on stand structure, songbird occupancy probabilities, a...

An econometric analysis was conducted with the intent of discovering the relationship between contractual provisions, as specified in timber sale notices, with high bids received for those timber sales. Specifically, the goal of this study was to determine the relationship between high bids for timber tracts and certain contractual stipulations that have not previously been explored to any grea...

Nonindustrial private forest landowners in Alabama were surveyed and assistance foresters' involvement in their management activities documented. Overall, assistance foresters have participated in some 58% of all forest management activities. Consulting foresters account for 45 to 50% of those activities involving assistance foresters. Public foresters have more small and low income landowners ...

The paper presents an experimental analysis of timber – framed wall panels with openings, coated with single fibre-plaster boards fastened to a timber frame. The present study is a continuation of the research work realized in the last years in reinforcing of the prefabricated timber-framed wall panels without any openings. The aim of the study presented here was to provide the information abou...

Timber gridshells have become a very popular, efficient, sustainable and beautiful structural application of timber. However, given the slender laths involved in this form of construction, there is concern over the durability of timber for this purpose, and Glass FRP (GFRP) laths have been proposed as a possible substitution. This paper considers this possibility. It goes on to look at the poss...

failure in timber structures occurs mainly in crucial points such as joints areas. therefore, the idea of using composite sheets in timber joints has been intro-duced as a method in order to increase the strength and ductility behaviour of timber joints. this research aims to study the behaviour of bolted joints in poplar and pine woods, which are reinforced by two types of gfrp sheets. a singl...

We construct an intertemporal model of rent-maximizing behaviour on the part of a timber harvester under potentially multi-dimensional risk as well as geographical heterogeneity. Subsequently, we use recursive methods (in particular, the method of dynamic programming) to characterize the optimal policy function, the rent-maximizing timber-harvesting profile. One noteworthy feature of our applic...

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...
