Beavers were once nearly extirpated across much of North America by the fur trade, but conservation efforts have allowed their numbers to recover in many watersheds. Where beaver populations return, their dams slow streamflow, raise water tables, and create wetlands that store water through dry seasons. Downstream communities have reported reduced flood damage and more reliable summer water flows in basins where beaver populations have rebounded.
Based on the passage, which inference is most strongly supported?
- Acheck_circle
Beaver activity provides hydrological benefits relevant beyond the immediate dam site
- B
Beaver populations have not recovered in any North American watershed
- C
Wetlands are unrelated to dry-season water availability
- D
Beavers cause significantly more flood damage than they prevent
Explanation
Slower flow, higher water tables, downstream reduced flooding, and reliable summer flows support A. B, C, D contradict the passage.
