Biodiversity refers to the variety and variability of life on Earth, encompassing all forms of living organisms including plants, animals, fungi, and microorganisms, as well as the ecosystems they inhabit. It includes diversity within species (genetic diversity), diversity between species (species diversity), and diversity of ecosystems (ecosystem diversity). This diversity is essential for maintaining ecological balance, providing ecosystem services, and supporting human well-being. Biodiversity ensures food security, regulates climate, purifies air and water, and maintains soil fertility. It also provides cultural and recreational benefits. The loss of biodiversity, which is currently happening at an unprecedented rate due to human activities, threatens the stability of ecosystems and the services they provide. In the context of urban areas, biodiversity plays a crucial role in mitigating environmental problems and improving the quality of life of urban residents. Urbanization is one of the most significant drivers of biodiversity loss. As cities expand, natural habitats are fragmented, degraded, or destroyed to make space for infrastructure, housing, and industries. This leads to the decline of native species, the spread of invasive species, and the loss of ecosystem services. Yet cities are not devoid of life; they can still harbor a surprising amount of biodiversity if managed properly. Urban ecosystems such as parks, gardens, green roofs, wetlands, and street trees can support numerous plant and animal species. Integrating biodiversity considerations into urban planning is critical for ensuring ecological sustainability and resilience in urban environments. This is where urban forestry emerges as a key strategy. Urban forestry refers to the planning, management, and care of trees and forests in and around urban areas. It is a multidisciplinary approach that combines elements of ecology, landscape architecture, environmental science, and urban planning to create and maintain green spaces within cities. Urban forestry is not just about planting trees; it involves managing urban tree populations for their environmental, social, and economic benefits. This includes
