Abstract:

Forest swamps are widely distributed in cold temperate regions, with important landscape and ecological functions. They are prone to conversion caused by complex factors. Forest swamp conversions involve forest swamping, meadow swamping, water body swamping, and conversion to farmland. An understanding of the landscape characteristics and primary environmental factors driving forest swamp conversions is imperative for exploring the mechanism of forest swamp conversions. We investigated the landscape characteristics of forest swamp conversions and quantified the relative importance of environme

Abstract:

Soil aggregates are the basic structural components of soil, which are important factors that can predict erosion resistance. However, few researchers have investigated the effects of forest conversion on the stability of soil aggregates, particularly in subtropical forests. In this study, soils from various depths (0 to 30 cm) were collected from four forest types (transformed from broadleaved forests (BMF) to combined coniferous broadleaved (CBMF), Chinese fir (FF), and bamboo forests (BF)) to determine the impacts of forest conversion on the physical and chemical properties of soil, water-s

Abstract:

Primary forest conversion greatly influences soil organic carbon (SOC) sequestration. However, our understanding of how primary forest conversion affects SOC fractions and chemical component evenness remains limited. We examined how primary forest conversion (from primary mixed broadleaved Korean pine forest to secondary broadleaved forest and coniferous plantation) affects free particulate OC (POC), aggregate-occluded POC, mineral-associated OC (MAOC), and their chemical component evenness via plant inputs (e.g., litter and fine roots) and microbial properties (e.g., microbial biomass and res

Abstract:

Land-use change and its effects on hydrological processes in a watershed strongly determine the adopted land and water resource management. Human activities that lead to the conversion of forest to non-forest land can continue to modify hydrological systems. This study was intended to analyze the variation in baseflow recession curves as a function of land-use change in the Keduang Watershed, Wonogiri Regency, Jawa Tengah Province. The results showed that the types of land-use conversions had the same model of recession: Qmodel= 0.9747*Exp(-0.2357*ts) for preserved forests, Qmodel= 0.1266*Exp(

Abstract:

It has been recognized that land use change affects soil organic carbon (SOC) dynamics and the associated microbial turnover. However, the contribution of microbial residue to SOC storage remains largely unknown in land use change processes. To this end, we adopted a “space for time” approach to examine the dynamics of SOC and amino sugars, which was a biomarker of microbial residue C, in different natural forest conversions. Three typical converted forests were selected: an assisted natural regeneration (ANR) and two coniferous plantations of Cunninghamia lanceolata (Lamb.) Hook (Chinese fir)

Collembolan communities in conifer plantations (Japanese cedar, Cryptomeria japonica) and secondary deciduous broad-leaved forests of varying ages were investigated to determine the extent to which forest conversion (broad-leaved to coniferous) affects the species richness and assemblage composition of Collembola in central Japan. Density and total species richness of Collembola not differed between the broad-leaved and cedar forests except immediately after clear-cutting. The amount of forest-floor organic matter was larger in cedar forests and positively correlated with the species richness

Abstract:

Conversion of natural broad-leafed evergreen forests into pure and mixed plantation forests in a subtropical area in China is a common practice in forest management. We investigated the effects of this conversion on litterfall, litter decomposition, and nutrient cycling. Monthly deposition of total N, P, K, Ca, and Mg through throughfall, stemflow, and various components of litterfall was investigated and compared over 3 consecutive years from January 1989 to December 1991 for both forests. The total annual fine litterfall over 3 years of observation was 4.8 t/ha in a pure plantation conifer f

Aceh's forest is a biosphere reserve, a world heritage, and a natural habitat for animals, such as the Sumatran tiger, Ceumpala Kuneng, and Sumatran elephant. However, Aceh's forests are currently experiencing a deficit related to uncontrolled land conversion, among others due to forest conversion to oil palm land, gold mining, illegal logging, and illegal new stone mining. Although Aceh's forest area as of 2019 was 2,989,212 hectares, the damage figure reached 15,140 hectares. Thus, this study aims to create a model of Acehâ€™s forest waqf to protect it from the natural damage caused by human

Increasing forest cover through reforestation and forest regrowth constitutes an essential contribution to mitigating the climate crisis, especially in the tropics. The Southeast Asian country of Lao PDR is on the brink of a forest transition, that is, a shift from net deforestation to net increases in forest area. This process is, however, contested and this article sheds light to power and politics in forest transitions and the implications for forests and people in Lao PDR and beyond.

Abstract The degradation of mangrove forests in the Konawe Selatan District has been very rapid over the past three decades. Increases in population growth in coastal areas have been associated with rapid development, including the need for land for housing and livelihood. This development has led to land conversion from mangrove forests to other uses. The aim of the research was to identify the pattern of spatial change of mangrove forests in South Konawe using a geospatial approach from 1984 to 2014.

Abstract:

Soil organic matter (SOM) is a crucial component of soil, through which physical, chemical, and biological characteristics interact in a local context. Within the forest category, the conversion of natural forests to monoculture plantations has raised concerns in Indonesia over the loss of soil functions, similar to conversion to agriculture. In natural forests, SOM can accumulate as part of a closed nutrient cycle with minimal nutrient losses; in plantation forestry, SOM decline and recovery can alternate over time, associated with larger nutrient losses.
