MidSE Aquatic CVI 2020

• The Species Index for aquatic ecosystems
• The Habitat Condition Index for aquatic ecosystems
• Conservation Hubs (partner focus areas)
• The Risk Index

The 4 inputs are combined as “barcodes” (e.g. 2421) in order of Species Index, Habitat Index, Hub, then Risk Index. The aquatic barcode is contained in the “A_Barcode” field of the aquatic CVI dataset.

The bar codes are then placed into 4 Action Classes and associated subcategories that characterize the existing network of lands and waters. The Action Classes are captured in the “A_ActCat” and “A_Class” fields of the aquatic CVI dataset.

• Maintain (1): Areas with a high concentration of Federal trust species (Species Index=3) & highly intact landscapes (Habitat Index=4)
• Enhance (2a-d): Areas with a high concentration of Federal trust species (Species Index=3) & moderately fragmented landscapes (Habitat Index=3), OR highly intact landscapes (Habitat Index=4) with a low or moderate concentration of Federal trust species (Species Index<3)
• Restore (3a-c): Areas with a moderate or high concentration of Federal trust species (Species Index>1) & highly fragmented landscapes (Habitat Index=2), OR moderately fragmented landscapes (Habitat Index=3) with a low concentration of Federal trust species (Species Index=1)
• Low Return on Investment (4a-e): All other combinations of Species Index & Habitat Index scores
