Today, in our environmental science lecture, we're discussing the impact of urban development on local wildlife. A recent study in Melbourne found that the presence of green roofs, which are covered with vegetation, can increase bird diversity by up to 30% compared to traditional rooftops. However, the study also noted that these roofs need to be planted with native species to be most effective. Non-native plants attracted fewer insects, which in turn reduced the number of insect-eating birds. The researchers suggested that building owners should consider installing green roofs not just for insulation, but as a key strategy for urban biodiversity conservation. They also highlighted the importance of connecting these roofs to nearby parks to create green corridors for wildlife movement.
