Cities and regions play a crucial role in conserving migratory species due to their strategic locations along migratory routes. Urban areas, often situated near key habitats like wetlands, estuaries, and forests, can serve as critical stopover points for species during migration. 

Ensuring urban ecosystems are preserved and restored is vital for providing safe passage, feeding, and resting sites. Moreover, cities can contribute to mitigating climate change impacts on migratory species through green infrastructure, such as creating urban green spaces, which help maintain ecological connectivity and reduce barriers to migration. Regions that implement policies for sustainable land and water use can significantly reduce habitat loss and fragmentation, directly benefiting migratory species. Collaborative efforts at regional and international levels are essential, as migratory species cross multiple jurisdictions. By integrating biodiversity conservation into urban planning and regional development strategies, cities and regions can significantly contribute to the global efforts to protect migratory species and maintain biodiversity.
