Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne examined the impact of community gardens on local biodiversity. The researchers found that these gardens, though small, supported a surprising variety of insect species, especially bees and butterflies. However, the key factor wasn't the size of the garden but the diversity of flowering plants. Gardens with at least ten different native plant species attracted three times more pollinators than those with only non-native ornamental flowers. Interestingly, the study also noted that gardens near natural reserves had higher species richness, suggesting that location matters as much as plant choice. So, for city planners, the recommendation is clear: prioritize native plant diversity over sheer garden area.
