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 ANAE attributes Estuarine ANAE attributes Landform High energy Upland Slope Low energy Upland (plateau) Lowland Substrate Unbroken rock Broken rock/Boulder/Cobble Pebble/Gravel Sand Silt Confinement (riverine only) Unconfined (floodplain) Semi-confined (discontinuous floodplain) Confined (non-floodplain) Structural macrobiota (SMB) Mangroves Saltmarsh Seagrass Macroalgae Filter feeders Soil Porous Peat (organic) Mineral (soil) Sand (non-soil) Non-porous Rock (non-soil) Substrate Clay Sedimentary (chemical/organic) Sedimentary (detrital) Unconsolidated Volcanic Light availability >15% 5-15% <5% OR Photic zone Low light zone Aphotic zone Water source Dominant water source (>70%) Surface water Groundwater Both surface and ground there is temporal dominance by one of the other) Localised rainfall Nutrient availability High Medium Low OR Oligotrophic Mesotrophic Eutrophic
