Freshwater ecosystems are among the most susceptible to biological invasions. The South American Ludwigia hexapetala is an aquatic plant that becoming increasing threat in many European waterbodies, recently including Italy. This study aimed define main parameters influencing early colonization stage of L. by overlapping percentage cover this species with environmental parameter data collected at 24 sites from six waterbodies north-central At each site, chemical and physical characteristics water (temperature, pH, dissolved oxygen, conductivity, nitrates, phosphates, ammonia, depth, transparency), grain size substrate level anthropogenic disturbance were evaluated. results showed although prefers shallow, warm, alkaline, moderately rich ions nutrients (especially phosphates) oxygen-poor waters, it can grow a wide range conditions. Moreover, as typical invasive alien species, spreads opportunistically disturbed, unstable sites. Thus, invade freshwater habitats different conditions subjected disturbance. However, suggest depth may be limiting factor which does not seem able colonise waters deeper than 1 m investigated sites, while has been observed significantly other countries longer invasion history. Detecting influence growth becomes crucial both identify at-risk initiate timely monitoring actions for develop better management control have already invaded.

Given the high number of non-native plants that are being introduced worldwide and time required to process formal pest risk analyses, a framework for prioritization management actions is urgently required. We therefore propose replicable standardized (eradication, control monitoring) invasive plants, combining expert knowledge, current future climatic suitability estimated by species distribution models (SDMs), clustering ordination techniques. Based on consultation using Italy as case study, plant were selected three categories identified: eradication, containment, monitoring. Finally, two further classes priorities proposed each actions: "high" "low" priority. Overall, SDMs highlighted very Continental Mediterranean bioregions most plants. Cluster analysis revealed distinct clusters with varying levels Italian bioregions. 1 exhibited higher across all bioregions, whereas grouped in 2 predominantly featured areas. 3 showed lowest values. Two variability bioclimatic within cluster, well their pattern. Lastly, third ordination, integrating spatial patterns, has allowed differentiation at both national bioregional scales. Specifically, seven earmarked eradication action, six monitoring while remaining deemed suitable containment. Our results methodology meet demand new early warning tools; predict location outbreaks, establish monitor species.

The tradition of floristic studies in Italy has made it possible to obtain a good knowledge plant diversity both on national and regional scale. However, the lack for some areas, advances systematics human activities related globalization, highlight need further aimed at improving knowledge. In this paper, based fieldwork herbaria literature surveys, we update Italian vascular flora analyze similarities between administrative regions. Four taxa, all exotic, were recorded first time Europe. detail, Elaeodendron croceum, Kalanchoë blossfeldiana, Sedum spathulifolium var. found as casual aliens, while Oxalis brasiliensis was reported historical record herbarium specimens. Furthermore, laxiflora confirmed alien species Status changes taxa proposed levels, well many new or level. Currently comprises 9150 which 7547 are native (of 1598 endemics) 1603 exotic multivariate analysis updated data scale showed clear distribution along latitudinal gradient, accordance with natural geographical location regions Italy. This pattern plants not affected by introduction species. Despite taxonomic methodological issues still open, obtained confirm important role investigations field herbaria, collaborative approach among botanists, order improve European flora.

Abstract An updated checklist of the Calabrian alien vascular flora is presented. By way field, bibliographic, and herbarium research, we recorded 382 taxa (representing almost 14% all regional flora), which 371 are angiosperms, nine gymnosperms, two ferns. In relation to state spread, majority species casual (207 taxa; 54%), followed by naturalized (127; 33%) invasive (48; 13%), these last include four on list Union Concern, sensu Regulation (EU) no. 1143/2014. The most represented families Asteraceae (39 taxa) Poaceae (39). Among genera, Amaranthus (nine taxa), Prunus , Euphorbia Oxalis (seven make up those with greatest number taxa. A total 21 were reported for first time, three them new European ( Camptosema rubicundum, Musa ×paradisiaca and, only continental Europe, Ipomoea hederacea ), Italian peninsula Pelargonium graveolens, Schinus terebinthifolia ) 16 Aeonium arboreum, Asparagus asparagoides, Aspidistra elatior, Bidens sulphurea, Catalpa bignonioides, Citrus ×aurantium, Crassula ovata, Cucurbita ficifolia, Dimorphotheca ecklonis, Graptopetalum paraguayense subsp. paraguayense, Kalanchoë laxiflora, Nicotiana tabacum, Phytolacca dioica Portulaca umbraticola, Talinum paniculatum, Tecomaria capensis ). terms residence status, there 291 neophytes (76%), 73 archaeophytes (19%), 18 aliens (5%); group (45 out 48) among Concerning life forms, abundant groups therophytes (30.1%, 115 phanerophytes (29.6%, 113 taxa). Regarding habitats, 72% occur in artificial (199 taxa, 52%) agricultural habitats (75 20%). native Americas (159; 41.6%), numerous also originated Asia (76; 19.9%) Africa (56; 14.7%). introduced ornamental purposes (55%). Over past decade, Calabria have increased from 190 current While this trend could be linked some extent increasing awareness problem intensity research over recent decades, it probably due introductions resulting globalization that relentlessly affects whole planet.

Habitat monitoring in Europe is regulated by Article 17 of the Habitats Directive, which suggests use typical species to habitat conservation status. Yet, Directive uses term “typical” but does not provide a definition, either for its reporting or impact assessments. To address issue, an online workshop was organized Italian Society Vegetation Science (SISV) shed light on diversity perspectives regarding different concepts species, and discuss possible implications habitat monitoring. this aim, we inquired 73 people with very degree expertise field vegetation science means tailored survey composed six questions. We analysed data using Pearson's Chi-squared test verify that answers diverged from random distribution checked effect experience surveyees results. found most agreed phytosociological method diagnostic characteristic to evaluate structural functional status habitats.

Remote Sensing (RS) is a useful tool for detecting and mapping Invasive Alien Plants (IAPs). IAPs on dynamic heterogeneous landscapes, using satellite RS data, not always feasible. Unmanned aerial vehicles (UAV) with ultra-high spatial resolution data represent promising detection mapping. This work develops an operational workflow Acacia saligna invasion along Mediterranean coastal dunes. In particular, it explores tests the potential of RGB (Red, Green, Blue) multispectral (Green, Red, Red Edge, Near Infra—Red) UAV images collected in pre-flowering flowering phenological stages A. saligna. After ortho—mosaics generation, we derived from DSM (Digital Surface Model) HIS (Hue, Intensity, Saturation) variables, calculated NDVI (Normalized Difference Vegetation Index). For classifying two built set raster stacks which include different combination variables. image classification, used Geographic Object-Based Image Analysis techniques (GEOBIA) Random Forest (RF) classifier. All classifications information (collected combinations variables) produced maps acceptable accuracy values, higher performances classification period images, especially + combination. The adopted approach resulted efficient method early IAPs, also complex environments offering sound support to prioritization conservation management actions claimed by EU IAS Regulation 1143/2014.
