Background information and definitions
Climate change increases the risk of extreme weather events, including flooding. Flood waters may cover habitat normally used by mammal species. For example, more than half of China’s mammal species were found to be exposed to risks from flooding (Ameca y Juárez & Jiang 2016). In addition to direct casualties from effects of water (such as drowning) flood water may alter the habitat, for example through changes to vegetation. Furthermore, mammal mortality may be higher when flood water persists for longer (Wuczyński & Jakubiec 2013). Enabling rapid removal of flood water, such as through creating drainage routes, may lessen such impacts.
