Impacts of Frequent Burning on Live Tree Carbon Biomass and Demography in Post-Harvest Regrowth Forest
submitted by menaa112 6 hours ago - Topic: Forestry
The management of forest ecosystems to increase carbon storage is a global concern. Fire frequency has the potential to shift considerably in the future. These shifts may alter demographic processes and growth of tree species, and consequently carbon storage in forests. Examination of the sensitivity of forest carbon to the potential upper and lower extremes of fire frequency will provide cruci...



Interactions between Fine Wood Decomposition and Flammability
submitted by menaa112 6 hours ago - Topic: Forestry
Fire is nearly ubiquitous in the terrestrial biosphere, with profound effects on earth surface carbon storage, climate, and forest functions. Fuel quality is an important parameter determining forest fire behavior, which differs among both tree species and organs. Fuel quality is not static: when dead plant material decomposes, its structural, chemical, and water dynamic properties change, with...

Temporal changes in SOM, N, P, K, and their stoichiometric ratios during reforestation in China and interactions with soil depths: Importance of deep-layer soil and management implications
submitted by kawhishe 19 hours ago - Topic: Forestry
Rapid increases in the global area of plantation forests necessitate a fuller understanding of their effects on soil fertility for continuous management and nutrient supply. Stands of a forest type widely distributed in the northern hemisphere, larch (Larix gmelinii) plantations, of 3 age groups (<20yr, 56 plots; 20–40yr, 73 plots; >40yr, 30 plots) were selected for the sampling...

Prediction of global bending stiffness of timber beams by local sampling data and visual inspection
submitted by jomobags466 1 day ago - Topic: Forestry
The results of visual inspection according to UNI 11119:2004 and bending tests made on 20 old chestnut (Castanea sativa Mill.) beams according to EN 408:2010 were statistically analyzed in order to provide a consistent and feasible procedure to predict their modulus of elasticity (MOE) in bending. Local data obtained from smaller size specimens was used for the prediction of the global mechanic...

A Comparison of Governance Challenges in Forest Restoration in Paraguay’s Privately-Owned Forests and Madagascar’s Co-managed State Forests
submitted by menaa112 1 day ago - Topic: Forestry
Governance of forest restoration is significantly impacted by who are the owners of and rights holders to the forest. We review two cases, Paraguay’s Atlantic forest and Madagascar’s forests and shrublands, where forest restoration is a priority and where forest ownership and rights are having direct repercussions on forest restoration. In Paraguay where a large proportion of forests are in...



The Impact of Windstorm Damage in the Assessment of the Carbon Balance in Even-Aged Fagus sylvatica L. Stands
submitted by menaa112 1 day ago - Topic: Forestry
Due to the fact that forest ecosystems can potentially mitigate the impact of climate change, the carbon balance of managed forests has caught the attention of a large scientific community. Some authors conclude that extending rotation lengths would actually favour the climate change mitigation effect since more carbon would be stored in the biomass on the average. However, when the occurrence ...

The extent and perceptions of vandalism as a cause of street tree damage in small towns in the Eastern Cape, South Africa
submitted by bioagri 2 days ago - Topic: Forestry
Street trees are important foundations of urban sustainability due to the ecosystem services that they provide society and the environment. However, street trees are vulnerable to vandalism and damage, especially when small, which constraints the flow of benefits they provide and also increases the costs of planting programmes. Despite being a common phenomenon, there is limited knowledge regar...


A description of the symptoms of Acute Oak Decline in Britain and a comparative review on causes of similar disorders on oak in Europe
submitted by bioagri 2 days ago - Topic: Forestry
Acute Oak Decline (AOD) is a relatively new decline-disease affecting both native oak species (Quercus robur and Q. petraea) in Britain. The key aim of this study was to describe the symptoms, and signs of AOD, to set a baseline. The second aim was to compare and review the European literature on what appear to be similar disorders on oak. AOD is characterized by four key features: weeping patc...

Forest harvest effects on mercury in streams and biota in Norwegian boreal catchments
submitted by bioagri 2 days ago - Topic: Forestry
Forest harvesting practices can potentially increase mercury run-off from catchments. A paired catchment experiment was conducted in a boreal forest in southern Norway, to test effects of forest harvest operations on (i) concentrations and fluxes of methylmercury (MeHg), total mercury (HgT), nutrients and dissolved organic matter (TOC), and on (ii) MeHg bioaccumulation in stream foodwebs. Thirt...


Effects of timber harvest within streamside management zones on salamander populations in ephemeral streams of southeastern Kentucky
submitted by bioagri 2 days ago - Topic: Forestry
Timber harvest is an important extractive, economic activity to many human economies, but it can be detrimental to ecosystem function and species viability therein by degrading and fragmenting forest habitat. Salamanders comprise a significant amount of forest community biomass, and given their sensitivity to environmental stressors, including those caused by timber harvest, they often serve as...

Soil carbon stocks and forest biomass following conversion of pasture to broadleaf and conifer plantations in southeastern Brazil
submitted by bioagri 2 days ago - Topic: Forestry
Increased soil carbon sequestration can potentially mitigate CO2 emission and can indicate sustainable forest management. This study aims to determine the relative influence of commercial plantation tree species on soil carbon following establishment on former tropical pastures. Soil carbon (organic horizon plus mineral soil from 0 to 45cm) and stemwood productivity were quantified from 6 to 34...


Drought-triggered western spruce budworm outbreaks in the interior Pacific Northwest: A multi-century dendrochronological record
submitted by bioagri 2 days ago - Topic: Forestry
Douglas-fir forests in the interior Pacific Northwest are subject to sporadic outbreaks of the western spruce budworm, a species widely recognized as the most destructive defoliator in western North America. Outbreaks of the western spruce budworm often occur synchronously over broad regions and lead to widespread loss of leaf area and decrease in growth rates in affected stands. In spite of th...

Delivering community benefits through REDD+: Lessons from Joint Forest Management in Zambia
submitted by bioagri 2 days ago - Topic: Forestry
In implementing reducing emissions from deforestation and degradation (REDD), significant attention is being paid to ensuring that communities stand to benefit. Safeguards to protect local people's rights and interests have been formulated in response concerns over the potential negative impact on communities of forest preservation. To fulfil safeguards, many sub-Saharan African countries are l...

Competitiveness of mechanized tree planting in Finland
submitted by bioagri 2 days ago - Topic: Forestry
Economic pressures and labor shortage are forcing forest owners to minimize silvicultural costs and manage their forests more intensively to enhance wood production and profitability. The need to improve the cost-efficiency of tree planting is spurring its mechanization. The cost-competitiveness and time consumption of mechanized tree planting in Finland were compared to manual planting (MP) in...

A generic approach to spatial individual-based modelling and simulation of plant communities
submitted by bioagri 2 days ago - Topic: Forestry
A general framework is proposed for the formulation and simulation of spatially explicit individual-based models of plant communities. A software implementation, siplab, was developed using the R statistical programming language. The scheme is a synthesis that encompasses many approaches from the literature, making possible to compare and combine their different components. Relationships betwee...
