Urban forestry in the context of "Smart city"

A smart city is an urban model that leverages technology, human capital, and governance to improve sustainability, efficiency, and social inclusion, which are considered goals for cities of the future. Smart cities use digital technology to collect data and operate services. Data is collected from citizens, devices, buildings, or cameras. Smart city applications are diverse and include, but are not limited to, traffic and transportation systems, power plants, utilities, urban forestry, water supply networks, waste disposal, criminal investigations, information systems, schools, libraries, hospitals, and other community services. The foundation of a smart city is built on the integration of people, technology, and processes, which connect and interact across sectors such as healthcare, transportation, education, infrastructure, etc. Smart cities are characterized by the ways in which their local governments monitor, analyze, plan, and govern the city. In a smart city, data sharing extends to businesses, citizens, and other third parties who can derive benefit from using that data. The three largest sources of spending associated with smart cities as of 2022 were visual surveillance, public transit, and outdoor lighting.

Smart cities integrate Information and Communication Technologies (ICT), and devices connected to the Internet of Things (IOT) network to optimize city services and connect to citizens. ICT can enhance the quality, performance, and interactivity of urban services, reduce costs and resource consumption, and to increase contact between citizens and government. Smart city applications manage urban flows and allow for real-time responses. A smart city may be more prepared to respond to challenges than one with a conventional "transactional" relationship with its citizens. Yet, the term is open to many interpretations. Many cities have already adopted some sort of smart city technology.

An urban forest is a forest, or a grove of trees, that grow within a city, town or a suburb. In a wider sense, it may include any kind of woody plant vegetation growing in and around human settlements.

As opposed to a forest park, whose ecosystems are also inherited from wilderness leftovers, urban forests often lack amenities like public bathrooms, paved paths, or sometimes clear borders which are distinct features of parks. Care and management of urban forests is called urban forestry. Urban forests can be privately and publicly owned. Some municipal forests may be located outside of the town or city to which they belong.

Tree care is the application of arboricultural methods like pruning, trimming, and felling/thinning in built environments. Road verge, greenways, backyard and park woody vegetation are at the center of attention for the tree care industry. Landscape architecture and urban forestry also set high demands on professional tree care. High safety standards against the dangers of tree care have helped the industry evolve. Especially felling in space-limited environments poses significant risks: the vicinity of power or telephone lines, insufficient protective gear (against falling dead wood, chainsaw wounds, etc.) and narrow felling zones with endangered nearby buildings, parking cars, etc. The required equipment and experience usually transcends private means and is often considered too costly as a permanent part of the public infrastructure. In singular cases, traditional tools like handsaws may suffice, but large-scale tree care usually calls for heavy machinery like cranes, bucket trucks, harvesters, and woodchippers.

Road side trees are especially prone to abiotic stress by exhaust fumes, toxic road debris, soil compaction, and drought which makes them susceptible to fungal infections and various plant pests like the spotted lantern fly. When tree removal is not an option, because of road ecology considerations, the main challenge is to achieve road safety (visibility of road signs, blockage-free lanes, etc.) while maintaining tree health.
