About the Manual
In Tasmania, models have been created for both Riffle and Edge habitats. The reach is defined as 100m of stream length and within the stream only. Areas of riffle and edge habitats that are representative of the reach should be chosen for sampling.
The riffle habitat is one of flowing broken water over gravel, pebble, cobble or boulder, with a depth greater than 10 cm.
The edge habitat consists of slow flowing or still waters adjacent to the bank, preferably with overhanging or emergent vegetation, undercut banks, root mats or other suitable habitat providing cover and refuge for macroinvertebrates.
