Medicinal and Aromatic Plants (MAPs) play a critical role in providing ecosystem services through their provision of herbal remedies, food natural skin care products, integration into local economies, maintaining pollinators’ diversity populations functioning. Mountainous regions, such as Chelmos-Vouraikos National Park (CVNP), represent unique reservoirs endemic MAP that require conservation prioritisation. This study aims to provide insights the sustainable management MAPs, contributing efforts protect Mediterranean biodiversity amid dual challenges climate land-use change, using suite macroecological modelling techniques. Following Species Distribution Modelling framework, we investigated vulnerability non-endemic MAPs changes. We examined potential shifts diversity, distribution, hotspots within CVNP. Our results revealed species-specific responses, with taxa facing severe range contractions initially expanding but eventually declining, particularly under change scenarios. Local are projected shift altitudinally, considerable area losses coming decades elevated species turnover predicted throughout CVNP, leading biotic homogenization. Climate changes jointly threaten calling for adaptive strategies, thus highlighting importance proactive measures, awareness raising, establishing plant micro-reserves, assisted translocation, promoting harvesting these offers vital managing global pressures, stressing need integrate ecological socioeconomic factors.

Endemic island species face heightened extinction risk from climate-driven shifts, yet standard models often underestimate threat levels for those like Quercus alnifolia, an iconic Cypriot oak with pre-adaptations to aridity. Through distribution modelling, we investigated the potential shifts in its under future climate and land-use change scenarios. Our approach uniquely combines dispersal constraints, detailed soil characteristics, hydrological factors, anticipated erosion data, offering a comprehensive assessment of environmental suitability. We quantified species’ sensitivity, exposure, vulnerability projected changes, conducting preliminary IUCN according Criteria A B. projections uniformly predict range reductions, median decrease 67.8% by 2070s most extreme Additionally, our research indicates alnifolia’s resilience diverse conditions preference relatively dry climates within specific annual temperature range. The designates alnifolia as Critically Endangered future, highlighting need focused conservation efforts. Climate changes are critical threats survival, emphasising importance modelling techniques urgent requirement dedicated measures safeguard this species.

This article explores the impacts of climate change on rural and natural landscapes in region Eastern Macedonia Thrace, northeastern Greece. The spatial distributions bioclimatic de Martonne Index phytoclimatic Emberger were calculated at a very high resolution (~500 m) for present conditions (1970–2000), two future time periods (2030–2060; 2070–2100), greenhouse gas concentration scenarios (RCP4.5; RCP8.5). results show significant changes, especially Rhodope Mountain range along almost whole length Greek–Bulgarian border, where forests ecosystem value are located, together with areas Evros river valley, as well coastal zone Aegean Sea. describes processes changes that can significantly modify study area’s landscapes. area reveals shift toward xerothermic environments over time, projected under extreme RCP8.5 scenario. By 2100, projections indicate around 40% agricultural eastern, southern, western regions will face Mediterranean semi-humid conditions, requiring supplemental irrigation sustainability. predicts approximately 42% experience sub-humid mild or cool winters. In comparison, 5% drier humid/sub-humid, warm winter conditions. These foreseen futures propose initial interpretations key landscape conservation, capital, services management.
