What is a potential disadvantage of planting diverse species in urban areas?

Planting diverse species in urban areas can lead to increased maintenance requirements due to the varied needs of different tree species. Each species has unique watering, pruning, disease management, and growth characteristics. Consequently, urban arborists and maintenance crews must be more vigilant and knowledgeable about the specific requirements of each species to ensure their health and longevity.

This diversity can necessitate tailored care schedules, special equipment, or additional training for maintenance staff, which can increase labor and resource allocation. While diversity in species is crucial for ecological resilience and pest management, it inevitably complicates the management aspect of urban forestry, leading to the increased maintenance burden.
