In today's lecture, we'll discuss the impact of urbanization on local wildlife. A key 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 research showed that green roofs and vertical gardens can partially mitigate these effects, but only if they are connected to larger parklands. For instance, a project in the city center introduced native plants on rooftops, which increased bee diversity by 30% within two years. However, the lecturer notes that such measures are insufficient for larger mammals like koalas, which require extensive corridors.
