Green roof research
If you’ve ever peered down from a planet the vast expanse of grey, dull rooftops, or walked along a busy street and glanced up at the high-rises, you might agree that cities severely lack greenery. Cities are rapidly losing natural habitats and city ecologists are running out of space at ground level. Many new developments are built on derelict or brownfield sites. But, these are often rich in rare plant and animal species, such as the black redstart, a bird that likes to nest in rubble. Instead, ecologists are looking to the skies as a last refuge for rare life. By using wasted space high above us on rooftops, we can recreate lost habitats and help make cities greener at the same time.
