Today in our environmental science lecture, we're discussing the impact of urban gardening on local biodiversity. A recent study in Melbourne observed that community gardens, especially those with native plants, attract a higher variety of pollinators like bees and butterflies. However, the researchers noted that the size of the garden didn't significantly affect species richness. Instead, the diversity of plant species was the key factor. Interestingly, gardens located near parks or green corridors showed a 30% increase in bird visits compared to isolated ones. The study suggests that even small plots can contribute to urban ecology if planted thoughtfully.
