Can Rooftop Gardens Act As Wildlife Corridors?
According to the Environmental Protection Agency, green roofs can mitigate urban heat islands, act as insulators to building, and enhance stormwater management. A recent study shows another benefit, green roofs are also important in increasing habitat connectivity for arthropods. Yes, they attract and provide habitat for arthropods that are not found in nearby ground areas. The study found small green roofs were just as beneficial in providing connectivity as large green roofs, and further, this connectivity turned out to be more important than microclimate for mobile arthropods. This study is good news for wildlife, adjustments such as encouraging rooftop gardens can help counter urban barriers.
