Plant invasions are major threats to the biodiversity and ecosystem function worldwide. In particular, forests one of highly affected ecosystems by invasive alien plant species (IAPS). spite several previous studies on invasion issues in forests, role tree canopy gaps establishment IAPS is poorly understood, particularly Nepal Himalaya. this study, we examined effect diversity abundance Shorea robusta dominated subtropical mixed broadleaved forest central Nepal. Fifty pairs plots (10 m × 10 m) were sampled, with a plot pair sampled gap its counterpart 20 away into interior within canopy. every plot, cover individual was estimated visually, other environmental variables such as canopy, light intensity, slope, litter depth, basal area measured. Higher number (9 species) their (31%) measured than (6 species; 5% cover), suggesting that these provide moderate level resistance invasions. Moreover, increased increasing size gap. Similarly, richness age but it independent size. Non-metric multidimensional scaling revealed community subset found gaps, opening has facilitated studied forests. Therefore, monitoring can be helpful detecting early stage so effective control measures implemented before widespread problematic at landscape level.

Medicinal plants research in Asia continues to receive significant national and international attention, particularly concerning its multiple roles poverty alleviation health care support. However, scientific information on the institutional arrangements, potentials of different medicinal production systems, utilization methods, remain highly fragmented. This incomprehensive base shades development a comprehensive agenda improve current body knowledge, at least context Asia. To address this impasse propose future perspectives, we systematically reviewed 247 journal articles, 15 reports, 28 book chapters. From reviews, five key lessons are drawn: (i) Asian plant systems demonstrate some dynamics, characterized by gradual but continuous shift from wild gathering cultivation, (ii) sub-regional variations exist with regards appreciation for traditional healing, modern healthcare, livelihoods support, (iii) knowledge effect multi-scale arrangements (formal informal) management practices is fragmented, (iv) very few studies dwell challenges commercialization, role middlemen, boom–bust cycle, raw material readiness, product quality, (v) law enforcement, benefit sharing, should be prioritized serve interest actors. further extend Asia, advance need empirical investigations performance their contribution diverse contexts.

Abstract Aim Climate change has increased the risk of biological invasions, particularly by increasing climatically suitable regions for invasive alien species. The distribution many native and species been predicted to under future climate. We performed modelling plants (IAPs) identify hotspots current climate scenarios in Nepal, a country ranked among most vulnerable countries invasions world. Location Nepal. Methods niches 24 out total 26 reported IAPs Nepal (2050 RCP 6.0) using an ensemble models. also conducted hotspot analysis highlight geographic different climatic zones, land cover, ecoregions, physiography federal states. Results Under climate, 75% will expand contrast contraction remaining 25% IAPs. A high proportion modelled occurred on agricultural lands followed forests. In aggregation, both extent intensity (invasion hotspots) increase scenarios. invasion towards high‐elevation mountainous regions. these regions, use is rapidly transforming due development infrastructure expansion tourism trade. Main conclusions Negative impacts livelihood, biodiversity ecosystem services, as well economic loss caused future, may be amplified if preventive control measures are not immediately initiated. Therefore, management should account vulnerability change‐induced into new areas, primarily mountains.

Invasive alien plant species (IAPS) pose a growing ecological threat, disrupting native ecosystems and biodiversity while challenging traditional conservation efforts. Ageratina adenophora, Chromolaena odorata, Mikania micrantha, belonging to the Banmara species, significant threat agriculture, resulting in crop loss increased production costs. Their detrimental effects on floral, faunal organisms, make them substantial menace biodiversity. Out of 219 flowering 30 are identified as invasive, adverse environmental outcomes impacting agricultural production. Remarkably, two notable C. odorata M. rank among world's top 100 most invasive agroecosystems rangelands. Additionally, A. adenophora is alert list European Mediterranean Plant Protection Organization (EPPO). The presence more prevalent central eastern Nepal, particularly Tarai, Siwalik, Middle Mountain regions, showing high degree invasion. have invaded High region Himalayas, micrantha Terai upper hilly regions Nepal. These disrupt forests, shrublands, wetlands, ecosystems, causing imbalances, habitat degradation, negative impacts from biological invasion seem be rise Nepal; however, national policy management responses appear insufficient address issue adequately. findings this study highlight urgent need challenges posed by these species.

Effective engagement is crucial for enhancing environmental decision-making processes, fostering more sustainable and equitable outcomes. However, the success of highly variable context-dependent. While theoretical frameworks have been developed to explain outcome variance in decision-making, they not yet tested digital contexts, leaving their applicability processes unclear. More broadly, there are unanswered questions about effectiveness tools achieving goals engagement, which become increasingly pertinent amidst growing concerns potential technologies exacerbating exclusions, ethical issues, systematically undermining democratic progress. This paper addresses this evidence gap by presenting findings from interviews with practitioners UK public, private, third sector organisations. Our results provide empirical insights into technical, ethical, inclusivity debates surrounding promoting accessible high-quality social interaction, place-based trustworthy credible indicate that while current theories applicable environments, key explanatory factors acquire new dimensions compared in-person contexts. Drawing on findings, study contributes novel expand theory explaining "what works" decisions, its relevance age. The concludes evidence-led recommendations improve remote settings.
