The following text is adapted from a 2019 essay on urban ecology.

City parks were long treated as decorative spaces, valued mainly for the calm they offered residents. Recent surveys, however, suggest that even small pockets of urban greenery support surprisingly dense populations of pollinators. Researchers monitoring rooftop gardens across three neighbourhoods recorded bee species that had not been documented in the region for decades, a finding that has ______ assumptions about which habitats matter for conservation.
