Policy at all levels, from international to local, has come to recognize the importance of urban trees for human and ecosystem wellbeing and makes demands on public administrations to increase, monitor, and manage urban tree cover accordingly [16]. For example, the United Nation's Sustainable Development Goal (SDG) 11.7 [17] and the _New Urban Agenda_[18] both call for increasing equitable access to public green spaces. At a national level, the future fourth Italian National Inventory of Forests and Forest Carbon Pools, planned for 2025, will include an increased focus on urban forests [19]. The National Biodiversity Future Center (NBFC) [20; 21], established as part of Italy's post-COVID-19 National Recovery and Resilience Plan (NRRP) [22], is at the forefront of tackling biodiversity loss in Italy, which threatens essential ecosystem services. However, implementing such policies is no simple feat. In increasingly complex governance systems, it often requires the coordination of very diverse stakeholders, including professionals and department directors working for municipal administrations, employees of private companies receiving public tenders, workers who carry out management tasks as a requirement for receiving public income or as rehabilitation, and non-profit associations, organizations, and citizens that adopt green spaces or volunteer their time for its upkeep [23]. Such a complex sharing of responsibility for urban and peri-urban trees and forests depends on efficient and up-to-date monitoring. Government agencies can improve their ability to monitor environmental resources and biodiversity conservation by using innovative tools and techniques. Indeed, information on the spatial distribution of tree species and vegetation maps are particularly useful for biodiversity monitoring [24; 25]. The availability of land cover information and the classification of urban tree species could be greatly facilitated by remote sensing (RS) with different data sources, such as very high resolution imagery, light detection and ranging (LiDAR) technology, and hyperspectral imagery (HSI) [2; 11]. The spatial resolution, radiometric resolution, and temporal resolution of imagery has increased with technological developments along with the availability of a growing number of satellite platforms [26]. Moreover, thanks to spectroscopy satellite missions, such as The Hyperspectral Precursor of the Application Mission (PRISMA) or the Environmental Mapping and Analysis Program (EnMAP) hyperspectral mission, very high spectral resolution has been achieved [27]. PRISMA, launched by the Italian Space Agency (ASI) in 2019, and EnMAP, launched by the German Aerospace Agency in 2022, are both in operational phases [28; 29]. Both high spectral resolution imaging spectroscopy missions produce data with a 30 km swath width. PRISMA is a first-generation model to test and advance hyperspectral imaging technology for practical applications [30]. EnMAP is quite similar and is also an experimental satellite [31]. By exploiting a very high spectral resolution, both missions provide additional information compared to multispectral missions, with which synergistic applications are expected [28; 31]. Hyperspectral data are widely used for tree classification [32] because they provide more accurate results [33].
