Restoration Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: April 4, 2025

Soil biological properties are sensitive indicators of land use changes. In particular, they have been widely used to assess the effects degradation and restoration. this study, we evaluated soil in degraded short‐term (<5 years) restored lands Brazilian semiarid region determine whether restoration efforts can enhance these properties. This study assessed three scenarios: native vegetation, land, land. Land resulted from deforestation, which exposed erosion, while involved constructing successive stone dams prevent increase moisture, reintroduce species. were during dry rainy seasons 2022 2023. We microbial biomass C, respiration, respiratory quotients, enzymatic activity as key generally higher season than season. Microbial C was highest with no significant differences between 2022. However, under showed an also areas acid phosphatase peaking Temporal stability varied for β‐glucosidase, urease activities, vegetation showing greater respiration β‐glucosidase. demonstrates that had a limited impact on improving lands.

Spatial variability in soil physicochemical properties across forest disturbances in the different forest divisions of Jharkhand, India

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: April 8, 2025

Forests provide a wide range of ecosystem processes and services, including net primary production, climate regulation, water nutrient cycling. However, forest ecosystems face immense pressure from various human-induced natural disturbances, which significantly contribute to their degradation. The restoration forests is critical global concern, particularly in Jharkhand, India, where are highly vulnerable mining activities land maintenance required cannot be comprehended without understanding soil. In this context, the present study was conducted analyse physicochemical properties soils under disturbances across all divisions Jharkhand. Stratification by grouping areas based on type (dense/moderately dense open/scrub/degraded forests) 31 divisions. Within each stratum, random sampling points were selected for division. Soil samples collected at three depths: 0–30 cm, 30–60 60–90 cm. soil analysed 12 parameters including, basic (pH, EC Organic Carbon), major nutrients (Available Nitrogen (AN), Available phosphorus (AP) Exchangeable Potassium (AK)), secondary Sulphur (AS)) micronutrients (Available.) Zinc (Zn), boron (B), iron (Fe), manganese (Mn) copper (Cu)). result two-way ANOVA showed significant (P < 0.05) variation pH, OC disturbance as well depth factors among Jharkhand state. All recorded decreasing trend NDF > MDF DF cm respectively. correlation matrix positive relation between Fe with Mn (0.975 P 0.001), pH (0.243 P 0.001) AK AP (0.221 0.001). calculation recommended dose fertilizers revealed that most require additional NPK, except Bokaro, Chatra South, Deoghar, Giridih East, West, Jamtara, Koderma, Medininagar, Sahibganj, Saraikela This research identifies deficiencies provides recommendations calculating fertilizer doses support sustainable management practices enhance plantation success.

The Impact of a Ski Piste on the Stock and Stoichiometry of Soil Carbon, Nitrogen, and Phosphorus: A Case Study on a Forest Area in Northeast China

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 846 - 846

Published: April 12, 2025

The construction of sports spaces such as ski resorts leads to deforestation, soil degradation and carbon (C) loss. However, the impact pistes on C nutrients remains unclear. an 18-year-old piste operation stock stoichiometry C, nitrogen (N), phosphorus (P), bulk density, water content across a 0–100 cm profile in forest area Northeast China was quantitatively assessed using equivalent mass method fixed depth method. overestimated N P stocks SP by 5% 8% relative used reference. demonstrated that N, were significantly reduced 27.4%, 21.3%, 27.5%, respectively, comparison undisturbed forest. Surface layers (0–10 cm) exhibited highest losses, while deep (>50 showed significant depletion. surface C:N (15.8%) C:P (38.0%) ratios, indicating decoupled nutrient constraints Soil compaction increased density but it deeper strata, correlating with altered physical interdependencies. findings highlight vertical stratification disturbance effects, emphasizing critical role stoichiometric controls methodological considerations assessing anthropogenic impacts ecosystems. These insights are vital for sustainable management mitigate degradation.

Compound drought and heat events (CDHEs) forest cover change influence regional carbon dynamics. Changes in vegetation biomass soil storage induced by often exhibit considerable uncertainty, previous research on the impacts of CDHEs dynamics is limited. To accurately quantify specific effects different regions, we employed a combined algorithm Carnegie–Ames–Stanford Approach (CASA) bookkeeping empirical models to examine impact changes during 2000–2022 Nanjing Shaoguan, Southern China. Using Geographical Detector model, then analyzed Next, used photosynthesis equation optimal response time forests (heat) calculate sequestration caused both regions 2000–2022.

Forests, Journal Year: 2024, Volume and Issue: 15(11), P. 1926 - 1926

Published: Oct. 31, 2024

Rill erosion, mostly affecting steep and long hillslopes, is one of the most severe effects deforestation wildfires in natural ecosystems. Specific monitoring accurate but simple models are needed to assess impacts these forest disturbances on rill detachment process. To address this need, study has simulated capacity (Dc) through flume experiments samples soils collected hillslopes after burning. The associations between Dc organic matter (OM) aggregate stability soil (WSA), two key parameters influencing process, have also been explored under conditions (deforested burned soils) using multivariate statistical techniques. Finally, linear regression predict from or hydraulic morphological variables (water flow rate, WFR, slope, S), set experiments, proposed for both conditions. Higher deforested sites compared (+35%) was measured. This increase associated with parallel decreases OM (−15%) WSA (−34%) wildfire-affected sites. However, discrimination those properties not sharp. Accurate equations (r2 > 0.76) interpolating shear stress (τ) estimate erodibility (Kr) evaluate resistance erosion be applied

Published: Dec. 20, 2024

Environmental policy and the expansion of bioeconomy sector has led to increased demand for wood products, pressuring forests. In order meet additional demand, foresters must either intensify forest management practices or alter area. One more observable shifts in comes form changes land use cover. Yet despite many short- long-term consequences land-use change, environmental impacts it are less explored forestry than agriculture. this paper, we conduct a literature review over period between 1993 2022 better understand how notions land-cover change included impact assessments related production products. Specifically, identified five categories studied found surprising dichotomy terminology land-use/land-cover practices. We present general trends methods indicators used discuss potential methodological conceptual challenges inherent literature. Our results particularly important light growing popularity data research, as highlight they have been integrated into existing assessment can improve them going future.
