Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that parks with native trees attract 30% more bird species than those with exotic plants. Interestingly, the size of the park mattered less than the diversity of plant life. For example, a small garden with ten different native species supported more birds than a large lawn with only grass. The researchers also noted that water features, like ponds, increased insect populations, which in turn provided food for birds. However, they warned that too many paved paths could reduce the positive effect. So, for city planners, the key is to prioritize plant variety over sheer area.
