Challenges of Governing Second-Growth Forests: A Case Study from the Brazilian Amazonian State of Para
submitted by menaa112 5 hours ago - Topic: Forestry
Despite the growing ecological and social importance of second-growth and regenerating forests across much of the world, significant inconsistencies remain in the legal framework governing these forests in many tropical countries and elsewhere. Such inconsistencies and uncertainties undermine attempts to improve both the transparency and sustainability of management regimes. Here, we present a ...



Xyleborus glabratus attacks and systemic colonization by Raffaelea lauricola associated with dieback of Cinnamomum camphora in the southeastern United States
submitted by babmellir2059 1 day ago - Topic: Forestry
Laurel wilt, caused by Raffaelea lauricola, is responsible for extensive mortality of redbay and other American members of the Lauraceae in the southeastern United States. Raffaelea lauricola is a mycangial symbiont of the redbay ambrosia beetle (Xyleborus glabratus), and the beetle and fungus were accidentally introduced from Asia. Branch dieback of camphortree (Cinnamomum camphora), an Asian ...

Initial characterization of an unidentified Armillaria isolate from Serbia using LSU-IGS1 and TEF-1-α genes
submitted by babmellir2059 1 day ago - Topic: Forestry
Armillaria species have a global distribution and play variable ecological roles, including causing root disease of diverse forest, ornamental and horticultural trees. Accurate identification of Armillaria species is critical to understand their distribution and ecological roles. This work focused on characterizing an unidentified Armillaria isolate from a Serbian forest using pairing, sequenci...

Cryphonectria hypovirus 1 (CHV-1) survey reveals low occurrence and diversity of subtypes in NE Spain
submitted by babmellir2059 1 day ago - Topic: Forestry
Cryphonectria parasitica (Murrill.) Barr is a necrotrophic fungus that affects European chestnut populations. In Catalonia (NE Spain), this fungus is widely spread affecting chestnut stands. In addition to vegetative compatibility (VC) types of the fungus, knowledge of the Cryphonectria hypovirus (CHV) occurrence is important to implement a biocontrol programme. We confirmed the presence of hyp...

Estimation of biomass and carbon storage of moso bamboo (Phyllostachys pubescens Mazel ex Houz.) in southern China using a diameter-age bivariate distribution model
submitted by ffirnondadeozs 2 days ago - Topic: Forestry
Carbon storage estimation for fast-growing bamboos remains limited because of its wide distribution and spatial variation. This study estimates biomass production and carbon storage of a moso bamboo (Phyllostachys pubescens Mazel ex Houz.) forest in southern China. A diameter–age bivariate distribution model based on the Weibull distribution function and a single bamboo biomass estimation...



Forest Sustainability in North Lebanon: A Challenging Complexity in a Changing Environment
submitted by rady963 2 days ago - Topic: Forestry
Forests sustainability is a challenging task in a complex socioeconomic context. North Lebanon is a critical zone harboring forests of key ecological value and is one of the most deprived regions in Lebanon with high poverty rates, where forests are heavily impacted by unsustainable anthropogenic practices. In the global frame of climate change scenarios, this paper tests a multistakeholder, mu...

On the causes of rising gross ecosystem productivity in a regenerating clearcut environment: leaf area vs. species composition
submitted by drdels 2 days ago - Topic: Forestry
Clearcutting a forest ecosystem can result in a drastic reduction of stand productivity. Despite the severity of this disturbance type, past studies have found that the productivity of young regenerating stands can quickly rebound, approaching that of mature undisturbed stands within a few years. One of the obvious reasons is increased leaf area (LA) with each year of recovery. However, a less ...


The scientific framing of forestry decentralization in Nepal
submitted by chenida 2 days ago - Topic: Forestry
Technical forest management plans have become a precondition for transferring authority to local institutions in processes of participatory forest management. The plans are intended to safeguard environmental values and are justified by their relevance in daily forest management. To serve these functions, the plans must be informed by accurate information about the forest and be actively used b...

Comparative analysis on the communication strategies of the forest owners' associations in Europe
submitted by chenida 2 days ago - Topic: Forestry
This research reports a comparative analysis of the communication strategy that forest owners' associations across Europe use to influence society on one side and the decision-makers on the other, in order to fulfill forest owners' interests. 60% of Europe's forests are privately owned by an estimated number of 16 million forest owners, who are represented by forest owners' associations. One of...


The legally allowable versus the informally practicable in Bolivia’s domestic timber market
submitted by chenida 2 days ago - Topic: Forestry
We analyze legality in the forest sector in Bolivia, focusing particularly on the domestic timber value chain in the northern Bolivian Amazon. Bolivia adopted wide-reaching forest, land and democratic regulatory changes since the mid-1990s that were partly intended to reduce illegal logging and related practices. The new forest regulations, in turn, led to new illegal practices because implemen...

Fire severity, size, and climate associations diverge from historical precedent along an ecological gradient in the Pinaleño Mountains, Arizona, USA
submitted by kawhishe 2 days ago - Topic: Forestry
In recent decades fire size and severity have been increasing in high elevation forests of the American Southwest. Ecological outcomes of these increases are difficult to gauge without an historical context for the role of fire in these systems prior to interruption by Euro-American land uses. Across the gradient of forest types in the Pinaleño Mountains, a Sky Island system in southeast Arizo...


Assessing spatio-temporal rates, patterns and determinants of biological invasions in forest ecosystems. The case of Acacia species in NW Spain
submitted by kawhishe 2 days ago - Topic: Forestry
Invasive species currently pose a major environmental challenge. Understanding their development and the factors associated with their expansion is the first step towards developing effective control measures. This work proposes the use of detailed spatio-temporal information from forest monitoring systems to assess the demographic rates, spatio-temporal patterns and spread determinants of inva...

Distribution of lignin and lignin precursors in differentiating xylem of Japanese cypress and poplar
submitted by tetobarnhom 2 days ago - Topic: Forestry
Lignin is an integral component of the cell wall of vascular plants. The mechanism of supply of lignin precursors from the cytosol into the cell wall of differentiating xylem has not yet been elucidated. The present study showed that a certain amount of coniferyl alcohol glucoside (coniferin) occurred in the differentiating xylem of Japanese cypress (Chamaecyparis obtusa), as previously reporte...
