Background information and definitions
Extreme events, such as short periods of unusually high or low temperatures, heavy flooding episodes, or intense storms with heavy rainfall, strong winds and scouring, can profoundly impact the marine environment through alterations in environmental conditions and sediment type (Smale & Wernberg 2013). Extreme events are expected to intensify with on-going climate change (Easterling et al. 2000), with likely negative consequences for subtidal benthic invertebrates. For instance, heat waves and flooding episodes have been associated with declines in benthic communities, including bivalves, crustaceans, and worms in Portugal (Grillo et al. 2011). Restoring habitats and/or habitat-forming (biogenic) species following extreme events may potentially help subtidal benthic invertebrate species recover following the disturbances.
Interventions aimed at restoring habitats and/or habitat-forming species, outside of the context of climate change, are listed in the following chapters: “Species management” and “Habitat restoration and creation”.
