Résumé :

Abstract As the value of forests for providing a feedstock for bioenergy increases, more land will probably be converted to fast-growing tree plantations to increase short-term production of cellulose. In general, plantations support fewer plant and animal species than native forests because plantations are greatly simplified in terms of tree and other plant species richness and in terms of many structural and process-related forest functions. However, native biodiversity can be retained in some plantation forests if careful management is used in all stages of plantation establishment, tending

Merchantable volume/ha was greatest at the 2.13 m spacing, followed by the less dense plantation and natural stand. Total volume/ha (trees > 1.3 m height) was also greatest in the 2.13 m plantation, followed by the natural stand and the 4.27 m plantation.

Differences in survival and growth of black and white spruce seedlings planted on boreal mixedwood sites were tested for stock types (transplant versus container), site preparation (Donaren disc trenching versus no trenching), and plantation types (open versus sheltered) in southeastern Manitoba after eight or nine growing seasons. Mortality of open plantation (32.3%) and container stock (32.5%) were significantly higher than sheltered plantation (23.7%) and transplant stock (22.8%), respectively. Donaren trenching slightly reduced the mortality of black spruce but significantly increased the

Résumé :

Understory vegetation is one of the most important links for improving forest biodiversity, and its restoration is conducive to sustainable forest development, energy flow, and nutrient cycling. However, little is known about the developmental dynamics and main driving factors of the long-time series coverage, biomass, diversity, and species composition of plantation understory vegetation. In a case study of three typical plantations, with a natural secondary forest as reference in the Loess Plateau of China, we collected understory vegetation from a Robinia pseudoacacia Linn. deciduous broad-

Résumé :

Policies to promote tree plantations in the Lao People’s Democratic Republic have been developed since independence to support national socio-economic and environmental goals, and in response to domestic and international markets. The effectiveness of these policies has been variable, and the resulting plantation wood value chains are poorly developed due to contradictory and confusing laws and regulations with inconsistent application and high transaction costs. Consequently, there has been limited tree plantation investment, and few investments have realized the anticipated benefits. Renewed

This study examines how soil pH and host plants influence mycorrhization trends in T. aestivum plantations across six plant species in eight Hungarian settlements, using root sampling and DNA analysis to assess plantations at three and six years of age. Tuber aestivum achieved over 30% mycorrhization, with Carpinus betulus showing the highest levels. DNA analysis identified eight undesired mycorrhizal

Résumé :

Rubber (Hevea brasiliensis Muell.) plantations are vital agricultural ecosystems in tropical regions. These plantations provide key industrial raw materials and sequester large amounts of carbon dioxide, playing a vital role in the global carbon cycle. Climate change has intensified droughts in Southeast Asia, negatively affecting rubber plantation growth. Limited in situ observations and short monitoring periods hinder accurate assessment of drought impacts on the gross primary productivity (GPP) of rubber plantations. This study used GPP data from flux observations at four rubber plantation

Forest degradation and mortality have been widely reported in the context of increasingly significant global climate change. As the country with the largest total tree plantation area globally, China has a great responsibility in forestry management to cope with climate change effectively. Mongolian Scots pine (Pinus sylvestris var. mongolica) was widely introduced from its natural sites in China into several other sandy land areas for establishing shelterbelt in the Three-North Shelter Forest Program, scoring outstanding achievements in terms of wind-breaking and sand-fixing.

Résumé :

Palm oil production is a key industry in tropical regions, driven by the demand for affordable vegetable oil. Palm oil production has been increasing by 9% every year, mostly due to expanding biofuel markets. However, the oil palm industry has been associated with key environmental issues, such as deforestation, peatland exploitation and biomass burning that release carbon dioxide (CO2) into the atmosphere, leading to climate change. This review therefore aims to discuss the characteristics of oil palm plantations and their impacts, especially CO2 emissions in the Southeast Asian region. The t

Résumé :

The established historiography of slavery includes a substantial body of work on the colonial period, with particular emphasis upon the Atlantic slave trade and the development of the plantation system and the slave community embedded within it. However, one key element in the organization of plantations has received little attention: the overseers. Slave owners and slaves are well represented in documentary sources, yet overseers, despite their importance in the plantation system, remain shadowy figures in the story of slavery in the colonial era.

There is an unexplored knowledge gap regarding the relationship between soil quality and mean annual increment (MAI) in forest plantations in Tanzania. Therefore, this study aimed to identify soil quality indicators and their impact on the mean annual increment (MAI) of Pinus patula at Sao Hill (SHFP) and Shume forest plantations (SFP) in Tanzania. The forests were stratified into four site classes based on management records. Tree growth data were collected from 3 quadrat plots at each site, resulting in 12 plots in each plantation, while soil samples were taken from 0 to 40 cm soil depth. An

Résumé :

Forest plantations are still often considered the antithesis of real nature. However, plantations can host many organisms. The problem is that some of the hosted species are regarded ad hoc as pests. The main aim of our paper was to study the carpenter ant (Camponotus ligniperdus) in windstorm habitats. We studied forests in East Bohemia, Czech Republic, and focused on the spatial distribution of snapped trees and the influence of selected forest characteristics on the incidence of ant nests. We found that the nests in the study area mainly occurred in Norway spruce, which is the most commerci

Soil acidification in tea plantations has become a key factor restricting the development of the tea industry. Biochar reduces soil acidity significantly and has good short-term effects of acidic soil improvement in tea plantation trials, but the duration of the effect and the long-term environmental effects of biochar are still unclear. In this study, the acidic tea plantation soil to which biochar was applied five years ago was studied. The biochar applied to the soil was separated and analyzed for surface elements, and the aluminum form of the soil was measured. The results showed that : (1

The four forest types include a primary mixed broadleaf – Korean pine (Pinus koraiensis Siebold & Zucc.) old-growth forest and three mid-aged regenerating forests, i.e., a secondary birch (Betula platyphylla Sukaczev) forest, a Korean pine plantation, and a Dahurian larch (Lari

Agroecological zoning system is essential to accelerate the production of plantation crops such as sugarcane. This is a tool that helps to identify the most suitable areas for growing specific crops based on the physical and biological characteristics of the land. The ideal conditions for sugarcane growth can be achieved from optimal planting land conditions and adequate climate and fertilization. Land use planning is key to the sustainability of plantation crops in Indonesia. In this study, we used land suitability evaluation for sugarcane cultivation using an agroecological zoning system.

Résumé :

Tropical reforestation initiatives are widely recognized as a key strategy for mitigating rising atmospheric CO2 concentrations. Although rapid tree growth in young secondary forests and plantations sequesters large amounts of carbon (C) in biomass, the choice of tree species for reforestation projects is crucial, as species identity and diversity affect microbial activity and soil C cycling via plant litter inputs. The decay rate of litter is largely determined by its chemical and physical properties, and trait complementarity of diverse litter mixtures can produce non-additive effects, which
