This change is a threat to the riparian zones and other floodplain forests. Some terrestrial beetles that exploit shoreline and floodplain habitats have physiological adaptations for surviving floods. Flooded areas have significant tracts of floodplain forest. Like artificial levees, they act to reduce the likelihood of floodplain inundation. Prairies, forests and floodplain forests lie here. The Stenkul Fiord site represents a series of deltaic swamp and floodplain forests. Geological evidence suggests that "Deinonychus" inhabited a floodplain or swamplike habitat.
