Stem Biomass Production of Paulownia elongata × P. fortunei under Low Irrigation in a Semi-Arid Environment
In semi-arid regions, afforestation with fast-growing species cultured with low irrigation can be an effective approach for environmental protection. An experiment was conducted to evaluate the stem biomass production of Paulownia in a semi-arid climate and clay soils under contrasting low-irrigation and fertilization treatments. The stem biomass at the stand level was estimated by applying all...


First report of Curvularia eragrostidis leaf spot on Populus deltoides
Poplars are affected by a large number of foliar pathogens in nurseries and in the field, which result in biomass reductions. Management of these diseases is essential to minimise losses. During field surveys between 2008 and 12, an unrecognized leaf spot disease was observed on several commercial clones of P. deltoides (G-48, Udai, WSL-22 & WSL-39). The pathogen was identified as Curvularia er...
Constructing a legitimate argument — Narrative techniques in the Ghana-EU VPA
This paper illustrates how an explicit focus on policy practitioner's use of narrative techniques in their policy arguments can be a way to identify when in the policy process risks of ‘good policies’ becoming ‘un-implementable’ emerge. A typology is developed identifying six specific types of narrative techniques used in policy argumentation: Framing, omission, fitting facts, means-to-...


CO2 emissions and economic impacts of using logging residues and mill residues in Maniwa Japan
In the face of increasing demand for woody biomass, mill residues continue being used more frequently than logging residues in Japan because of their relative ease of use. The Japanese government set a target ratio of logging residue use to 30% by 2030 compared with less than 1% in 2009. This study examined GHG emissions and the economic effects of logging and mill residues, which are employed ...
Microclimate and Modeled Fire Behavior Differ Between Adjacent Forest Types in Northern Portugal
Fire severity varies with forest composition and structure, reflecting micrometeorology and the fuel complex, but their respective influences are difficult to untangle from observation alone. We quantify the differences in fire weather between different forest types and the resulting differences in modeled fire behavior. Collection of in-stand weather data proceeded during two summer periods in...


Evaluation of the spatial linear model, random forest and gradient nearest-neighbour methods for imputing potential productivity and biomass of the Pacific Northwest forests
Increasingly, forest management and conservation plans require spatially explicit information within a management or conservation unit. Forest biomass and potential productivity are critical variables for forest planning and assessment in the Pacific Northwest. Their values are often estimated from ground-measured sample data. For unsampled locations, forest analysts and planners lack forest pr...
Green Infrastructures and Urban forests for improving the environment and the quality of life
Il 17 November 2014, at Aula Marconi CNR, P.le Aldo Moro, 7 ROMA, COST FP1204 and IBAF-CNR organise the conference Green Infrastructures and Urban forests for improving the environment and the quality of life Programme 10.00 – Welcome Luigi Nicolais, President of CNR Enrico Brugnoli, Director of Department of Earth System Science and Environmental Technologies.

Internationalization of the forest industry: a corporate-level analysis
With far-reaching impacts of economic globalization, the internationalization process of the forest industry has been accelerated. Particularly since the 1990s, internationalization has progressed intensively through industry consolidation and production relocation. Forest industry firms have geographically shifted their operations from traditional production bases in developed countries to eme...
An Analysis of Wood Market Balance Modeling in Germany
A Wood Market Balance model provides a method for generating a highly aggregated summary of wood availability and use. It is an important source of information for the forestry and wood industry sectors. This paper compares the Wood Balance and Wood Resource Balance modeling tools widely used in Germany today, lists the differences between the two and shows why the Wood Resource Balance in its ...

The role of social and environmental attitudes in non-market valuation An application to the Białowieża Forest
The purpose of this study is to investigate the impact of non-economic motivations such as altruism and environmental concerns on social preferences and hence willingness to pay (WTP) for changes in forest management strategies in the Białowieża Forest in Poland. We used data from a discrete choice experiment (CE) with attributes describing changes in the quality of the forest and recreation....
Mozambique’s charcoals—energetic properties of nine native species
Most of the charcoal produced commercially in Mozambique is from natural forest and its production often affects negatively the environment. Nine species of high commercial value were analyzed and the results indicate comparable quality of their charcoal and that made from species of low commercial value. The dissemination of this knowledge could relieve pressure on the valuable species and als...

Evaluation of compressive strength for the wood Eucalyptus grandis using ultrasonic wave propagation
This study presents a methodology to evaluate the compressive strength of unloaded dry wood of Eucalyptus grandis (moisture up to 12 %) through a statistical model that correlates this mechanical property with the velocity of ultrasonic waves. Properties were measured in the directions parallel and perpendicular to the fibers. presented good correlation with linear regression models.
Host plant selection and resource utilisation by Asian longhorn beetle Anoplophora glabripennis (Coleoptera: Cerambycidae) in southern England
In February 2012, an outbreak of Asian longhorn beetle, Anoplophora glabripennis (Motschulsky), was discovered at Paddock Wood in Kent, in southern England, next to a small industrial premise where a previous company had imported stone from China. Anoplophora glabripennis is a serious pest of deciduous broadleaved trees and is native to China, but it has been transported around the world in woo...
Improving urea formaldehyde resin properties by glyoxalated soda bagasse lignin
The aim of this research was a reduction of formaldehyde emission and the improvement of the water resistance of urea formaldehyde (UF) resins by incorporating glyoxalated soda bagasse lignin. For this purpose, various contents of unmodified and glyoxalated lignins (10, 15 and 20 %) were added at pH = 7 instead of second urea during the UF resin synthesis. The properties of the resins as wel...
Invasion of Winter Moth in New England: Effects of Defoliation and Site Quality on Tree Mortality
Widespread and prolonged defoliation by the European winter moth, Operophtera brumata L., has occurred in forests of eastern Massachusetts for more than a decade and populations of winter moth continue to invade new areas of New England. This study characterized the forests of eastern Massachusetts invaded by winter moth and related the duration of winter moth defoliation estimated using dendro...
