Forests around the world, vital for ecological, economic, and social functions, are facing increasing threats such as deforestation habitat fragmentation. This study introduces “succolarity” to analyse forest connectivity fragmentation directionally in Romanian Carpathians from 2000 2021. Besides traditional indices fractal index (FFI), disorder (FFDI), local connected dimension (LCFD), succolarity, two novel proposed: potential succolarity delta (Δ) which provide nuanced insights into environmental changes human interventions forests worldwide. The tests showed invariance at image scale sensitivity obstacles different scenarios. combined analysis of reveals dynamic patterns connectivity, fragmentation, spatial disturbance. directional highlight enhance understanding patterns. FFI FFDI show levels across mountain groups, while LCFD details connectivity. adaptability method makes it globally applicable, supporting biodiversity conservation landscape management. In conclusion, integration provides a robust methodology comprehensive advancement not only supports sustainable management but also represents versatile approach applicable ecosystems worldwide, ensuring long-term resilience forested regions.

Distribution pattern of large old Ginkgo biloba in China under climate change scenarios

Abstract Large old Ginkgo biloba trees (LOGTs), with profound ecological and cultural significance in China, face increasing threats from climate change human activities. We employed the BIOCLIM DOMAIN species distribution models to predict their spatial patterns under present doubled‐CO 2 scenario 2100. collected 604 validated LOGT occurrence records data on 19 bioclimate factors for analysis. Our study yielded a geographic pattern covering wide latitudinal belt extending south subtropical temperate zones central eastern concentrating low elevations coastal regions. The principal component analysis identified dominant bioclimatic shaping distribution, namely annual precipitation winter temperatures. generated predicted suitable habitats that match range well. However, future scenario, indicated habitat retentions mainly core areas losses southern edge of scattered pockets elsewhere. Some retained habitats, including excellent ones, will suffer fragmentation. new may permit some expansion migration but are beset by small patch size large interpatch distance, bringing fragmentation gene flow restrictions. anticipated projected decline highlights considerable poses long‐term survival precious natural‐cum‐cultural resource. Understanding underlying drivers distillation practical conservation measures can foster sustainable management vis‐a‐vis looming global change.

Convergence and divergence in science and practice of urban and rural forest restoration

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Год журнала: 2023, Номер 99(1), С. 295 - 312

ABSTRACT Forest restoration has never been higher on policymakers' agendas. Complex and multi‐dimensional arrangements across the urban–rural continuum challenge restorationists require integrative approaches to strengthen environmental protection increase outcomes. It remains unclear if urban rural forest are moving towards or away from each other in practice research, whether comparing research outcomes can help stakeholders gain a clearer understanding of interconnectedness between two fields. This study aims identify challenges opportunities for enhancing both systems by reviewing scientific evidence, engaging with key using an framework. Using Society Ecological Restoration's International Principles as discussion topics, we highlight aspects convergence divergence fields broaden our promote management address future conditions. Our findings reveal that have convergent divergent aspects. We emphasise importance tailoring goals objectives specific contexts need design different institutions incentives based social ecological needs regions. Additionally, discuss achieving high levels go beyond traditional ecology plan, implement, monitor, adaptively manage restored forests. suggest rivers watersheds could serve common ground linking landscapes interact measures. note potential expanding creative vision associated increasing tree‐containing environments cities generate more diverse resilient settings. underscores value addressing conditions continuum. framework provides valuable insights policymakers, researchers, decision‐makers advance field The rural–urban interface serves point restoration, benefit other's expertise.

The Role of Artificial Lakes Located in Forests in the Context of Small Retention, Biodiversity and Climatic Changes—Evidence From Southern Poland

ABSTRACT Drought has an effect on hydrologic conditions and water quality under climate change. Small retention in forests is one of the priority investment programs implemented recent years, supported by European Union. This study aimed to assess ecological forest lakes using macrophytes benthos organisms diversity as indicator ecosystem climatic changes. The was carried out artificial serving surface context biodiversity changes its role water. Despite systematic maintenance activities, a long period lake existence significantly determines natural biological processes occurring riparian habitats. analysis showed low values salinity indicators concentration nitrogen phosphorus. pH ranged from 6.2 7.6; showing slightly acidic or within limits neutral. model plant associations occurrence 24 species plants nine assemblages Phragmitetea Potametea classes (Biocenotic index 1.007–1.692). human condition, assessed ESMI biocenotic indices, good (0.416–0.648). Climate change, expressed increase frequency dry creates situation filling with water, which, taking into account their small depth, results dynamically changing for development phytolittoral. Along phytolittoral changes, communities density number taxa also fluctuate. It should be assumed that ongoing these phenomena will probably intensify, which lead entire ecosystems at animal levels.

Improving the Individual Tree Parameters Estimation of a Complex Mixed Conifer—Broadleaf Forest Using a Combination of Structural, Textural, and Spectral Metrics Derived from Unmanned Aerial Vehicle RGB and Multispectral Imagery

Geomatics, Год журнала: 2025, Номер 5(1), С. 12 - 12

Individual tree parameters are essential for forestry decision-making, supporting economic valuation, harvesting, and silvicultural operations. While extensive research exists on uniform simply structured forests, studies addressing complex, dense, mixed forests with highly overlapping, clustered, multiple crowns remain limited. This study bridges this gap by combining structural, textural, spectral metrics derived from unmanned aerial vehicle (UAV) Red–Green–Blue (RGB) multispectral (MS) imagery to estimate individual using a random forest regression model in complex conifer–broadleaf forest. Data 255 trees (115 conifers, 67 Japanese oak, 73 other broadleaf species (OBL)) were analyzed. High-resolution UAV orthomosaic enabled effective crown delineation canopy height models. Combining improved the accuracy of height, diameter at breast stem volume, basal area, carbon stock estimates. Conifers showed high (R2 = 0.70–0.89) all parameters, 0.89, RMSE 0.85 m). The oak 0.11–0.49) OBL 0.38–0.57) was improved, achieving relatively area 0.57, 0.08 m2 tree−1) volume 0.51, 0.27 m3 tree−1). These findings highlight potential accurately estimating
