Today in our environmental science lecture, we'll discuss the impact of urban green spaces. A recent study monitored two parks in Manchester over a year. The first park, with native trees, attracted 30% more bird species than the second, which had ornamental plants. However, the second park showed higher insect diversity, likely due to its varied flowering plants. Interestingly, both parks had similar noise levels, but visitors reported feeling more relaxed in the native-tree park. This suggests that biodiversity alone doesn't determine human perception; tree cover and shade play a key role.
