  • 6. Ecosystem indicators  Biodiversity and habitat loss –Metrics: wetland disconnectivity, Red List Index  Water management impacts on ecosystem integrity –Metrics: Estimated total river fragmentation, estimated total flow disruption, estimated total density of dams 6
  • 7. Ecosystem indicators (continued)  Fish threat –Metrics: Average annual catches of fish, estimated potential fish production, proportion of non- native fish species  Basin productivity –Metrics: water storage capacity, flow variability, and regulation, filtering of water capacity, absorbing and buffering capacities 7
