Urban development primarily impacts migratory patterns by altering habitats and creating barriers that disrupt traditional migration routes. Cities often replace natural habitats with roads and buildings, affecting the availability of resources like food and shelter. This can lead to a decline in certain species populations as they struggle to adapt. Moreover, urban areas can create heat islands that affect local climates, further influencing migratory behaviors. The resultant changes can lead to increased conflict between wildlife and human populations as animals seek alternate paths and resources.
