* Modifications to MFAT (or data-derived relationships) were based on relationships derived from the current location of vegetation communities.
† Further modifications were made based to remove the negative response to permanent inundation, as these trees are assumed to be on the edges of channels and wetlands, not on the floodplain.
+ Colonial nesting waterbirds are less likely to breed in the Lower Murray and are more likely to be of importance near the SA border.
‡ Modifications to MFAT were based on information contained in Ecological Associates (2010).
^ Modifications to MFAT were based on information contained in Overton et al. (2009).
Note that for all MFAT-derived curves, responses listed by MFAT as 0 were altered to 0.05 due to the difference in the interpretation of a 0 response (i.e., unfavorable habitat vs. irreparable harm) between MFAT and this project. Refer to the Methods for further information.
