Freshwater Biogeographic Provinces

Broad geographic areas such as Queensland can cover a diverse and complex array of ecosystem types which can make understanding aquatic ecosystem processes difficult. This heterogeneity is related to geographic distance and the presence of different landscape attributes. Regionalisation is a process used to divide a large area into smaller areas with similar (less variable) ecosystem types. This reduction in variability is beneficial to condition assessments because it increases the efficiency of the monitoring effort applied within a sampling program.

Quick facts

is the estimated length of the Flinders River—the longest river totally within Queensland borders.[1]
is the estimated length of the Murray-Darling River that runs from Qld through NSW and Vic before finishing up in SA[1].

Some basic characteristics of riverine or lotic (flowing, moving) systems include:

  • unidirectional flowing water (downhill)
  • erosion and downstream transportation and deposition of sediments
  • links to floodplains
  • linear change in morphology and ecology
  • catchments made up of branching network of streams and rivers that are in dynamic equilibrium with the landscape and its climate
  • catchments connect the landscape and the sea.

The riverine ecosystems in Queensland have been divided into Freshwater Biogeographic Provinces (FBPs) using broad patterns in the natural distribution of faunal communities.
