The urban canals of the city of Padua represent a unique and important ecosystem, as they act as a link between natural environments and highly anthropised urban contexts of a certain historical and cultural importance. These watercourses are home to a peculiar biodiversity, including numerous plant species, whose ecological dynamics are affected by both the influence of the natural environment and the pressures resulting from human activity. However, knowledge of the biological richness of these environments often remains limited. The objective of this study is twofold: on the one hand, to monitor and analyse the vegetation present in and along the banks of Padua's urban canals, and on the other, to promote the dissemination and awareness of the biodiversity of these ecosystems among the local population. During the period between May and September 2024, a series of field trips were made, both on foot and by boat, to collect data on aquatic and riparian flora. Some species were identified directly in the field, while others were collected for identification in the laboratory using dichotomous keys. A herbarium of representative samples was also compiled. From the data obtained, a floristic list of the species present was compiled, followed by an analysis of the biological and chorological spectrum of the flora monitored. During the study, in-depth studies were carried out on certain species, selected on the basis of specific ecological characteristics of importance, such as species potentially dangerous to the ecosystem as invasive or native species of ecological and cultural interest. At the same time, a thorough search was conducted for species protected at a regional level and those included in the red lists at different levels: global, European, Italian, Veneto and Padua, in order to assess the conservation status of the local flora and the possible impact of environmental conditions on the habitats of these species. In addition, a historical comparison with past records was carried out that highlighted changes in floristic composition over time, offering insights into conservation considerations. The study also investigated the correlation between aquatic vegetation characteristics and water chemistry parameters, providing insights into the impact of water quality on biodiversity and vice versa. The project concludes with the design of information panels dedicated to the plant biodiversity of Padua's urban canals, with the intention of increasing the population's awareness of the importance of conserving these ecosystems. This work aims not only to provide a current snapshot of the flora of Padua's urban canals, but also to foster greater knowledge and protection of these unique ecosystems through an educational and sustainable approach.
I canali urbani della città di Padova rappresentano un ecosistema unico e di rilevante importanza, in quanto fungono da collegamento tra ambienti naturali e contesti urbani altamente antropizzati e di una certa rilevanza storica e culturale. Questi corsi d’acqua ospitano una biodiversità peculiare, che comprende numerose specie vegetali, le cui dinamiche ecologiche risentono sia dell’influenza dell’ambiente naturale che delle pressioni derivanti dall’attività umana. Tuttavia, la conoscenza della ricchezza biologica di questi ambienti rimane spesso limitata. L’obiettivo di questo studio è duplice: da un lato, monitorare e analizzare la vegetazione presente all'interno e lungo gli argini dei canali urbani di Padova, e dall’altro, promuovere la divulgazione e sensibilizzazione sulla biodiversità di questi ecosistemi nella popolazione locale. Durante il periodo tra maggio e settembre 2024, sono state effettuate una serie di uscite sul campo, sia a piedi che in barca, per raccogliere dati sulla flora acquatica e ripariale. Alcune specie sono state identificate direttamente in campo, mentre altre sono state raccolte per essere identificate in laboratorio mediante l’utilizzo di chiavi dicotomiche. È stato inoltre realizzato un erbario di campioni rappresentativi. Dai dati ottenuti, è stato stilato un elenco floristico delle specie presenti, seguito da un'analisi dello spettro biologico e corologico della flora monitorata. Durante lo studio sono stati eseguiti approfondimenti su determinate specie, selezionate in base a specifiche caratteristiche ecologiche di rilievo, come specie potenzialmente pericolose per l’ecosistema in quanto invasive o specie autoctone di interesse ecologico e culturale. Parallelamente, è stata condotta una ricerca accurata delle specie protette a livello regionale e di quelle inserite nelle liste rosse a diversi livelli: globale, europea, italiana, veneta e padovana, al fine di valutare lo stato di conservazione della flora locale e il possibile impatto delle condizioni ambientali sugli habitat di queste specie. In aggiunta, è stato eseguito un confronto storico con documenti del passato che ha evidenziato le variazioni nella composizione floristica nel corso del tempo, offrendo spunti per riflessioni sulla conservazione. Lo studio ha anche approfondito la correlazione tra le caratteristiche della vegetazione acquatica e i parametri chimici delle acque, fornendo indicazioni sull’impatto della qualità dell’acqua sulla biodiversità e viceversa. Il progetto si conclude con la progettazione di pannelli divulgativi dedicati alla biodiversità vegetale dei canali urbani di Padova, con l'intento di aumentare la consapevolezza della popolazione riguardo all'importanza della conservazione di questi ecosistemi. Questo lavoro mira non solo a fornire una fotografia attuale della flora dei canali urbani di Padova, ma anche a favorire una maggiore conoscenza e tutela di questi ecosistemi unici attraverso un approccio educativo e sostenibile.

Abstract
The urban canals of the city of Padua represent a unique and important ecosystem, as they act as a link between natural environments and highly anthropised urban contexts of a certain historical and cultural importance. These watercourses are home to a peculiar biodiversity, including numerous plant species, whose ecological dynamics are affected by both the influence of the natural environment and the pressures resulting from human activity. However, knowledge of the biological richness of these environments often remains limited. The objective of this study is twofold: on the one hand, to monitor and analyse the vegetation present in and along the banks of Padua's urban canals, and on the other, to promote the dissemination and awareness of the biodiversity of these ecosystems among the local population. During the period between May and September 2024, a series of field trips were made, both on foot and by boat, to collect data on aquatic and riparian flora. Some species were identified directly in the field, while others were collected for identification in the laboratory using dichotomous keys. A herbarium of representative samples was also compiled.
