In today's lecture, we'll discuss the impact of urbanization on local wildlife. A recent study in Melbourne found that while some species, like possums, adapt well to city life, others, such as certain ground-nesting birds, struggle due to habitat fragmentation. Interestingly, the study revealed that green roofs and vertical gardens can provide crucial corridors for insects and small mammals. However, researchers emphasize that these measures are not a complete substitute for natural habitats. They suggest that urban planners should prioritize preserving existing parklands over creating new artificial green spaces, as mature trees support a higher diversity of native species.
