Level 3 attributes The attributes to be considered when applying the ANAE framework are listed in Table 7. While all of the attributes listed in Table 7 were considered relevant to the current project, it was recognised in Stage 1 that some refinement to attribute definitions and metrics was required before attribute data were assigned to the respective aquatic ecosystems (Cottingham et al. 2012). These refinements are considered in the following sections. 7: Level 3 attributes included in the ANAE Classification Framework Riverine, Lacustrine, Palustrine and Floodplain Estuarine ANAE attributes ANAE attributes Landform Substrate High energy Unbroken rock Upland Broken rock/Boulder/Cobble Pebble/Gravel Slope Sand Low energy Silt Upland (plateau) Lowland Confinement (riverine only) Structural macrobiota (SMB) Unconfined (floodplain) Mangroves Semi-confined (discontinuous floodplain) Saltmarsh Confined (non-floodplain) Seagrass Macroalgae Filter feeders Soil Light availability Porous >15% Peat (organic) 5-15% Mineral (soil) <5% OR Sand (non-soil) Photic zone Non-porous Low light zone Rock (non-soil) Aphotic zone Substrate Clay Sedimentary (chemical/organic) Sedimentary (detrital) Unconsolidated Volcanic Water source Nutrient availability Dominant water source (>70%) High Surface water Medium Groundwater Low Both surface and ground there is temporal OR dominance by one of the other) Oligotrophic Localised rainfall Mesotrophic Eutrophic
