0 = > 3 downstream dams (low)
1 = 3 downstream dams
2 = 2 downstream dams
3 = 1 downstream dams
4 = 0 downstream dams (high)
Defining the Spatial Extent of Ecosystems
Landscapes and waterscapes indicators were defined as features that applied across all terrestrial and aquatic ecosystems and no refined extent was needed.
In some situations, this index of connectivity can improve even as you move upstream. This is because the calculation includes barriers off the mainstem of the river that are not necessarily “downstream” of other watersheds.
The South Atlantic ecosystem indicators serve as the South Atlantic LCC's metrics of success and drive the identification of priority areas for shared action in the Conservation Blueprint. To learn more about the indicators and how they are being used, please visit the indicator page. Check out the Blueprint page for more information on the development of the Blueprint, a living spatial plan to conserve our natural and cultural resources.
