Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne compared two types of parks: large central parks and small neighborhood gardens. Researchers found that small gardens, though less visited, actually support a higher diversity of bird species per square meter. This is because they provide varied microhabitats and are often connected by tree-lined streets, which act as corridors. However, the study also noted that central parks are crucial for larger mammals and for recreational activities. Therefore, the conclusion is not to prioritize one over the other, but to plan a network that integrates both sizes effectively.
❓ What did the study in Melbourne find about small neighborhood gardens?
A. They attract more visitors than central parks.
B. They have higher bird species diversity per area than central parks.
C. They are mainly used by larger mammals.
D. They lack connections to other green areas.
✅ 正确答案
They have higher bird species diversity per area than central parks.
