... variables) and by the nature of the data these sampling methods can provide. Capture techniques are the preferred method but capture using mesh (‘gill’) nets is limited by stream flows and the presence of fish and/or large woody debris (‘snags’). Fyke netting, the other preferred method, is largely...

...D. Bryant; D. Crowther; P. Papas Burrowing crayfish are notoriously difficult to sample owing to their cryptic nature and subterranean habitat. The most commonly employed sampling method is burrow excavation but it is labour-intensive, destroys the burrow and hence is not repeatable. Consequently...

... in the future to correct raw sighting data. A better solution may be to use “double sampling”, which is a well-established sampling method. Each time an aerial survey is conducted, a subsample of the transacts surveyed would be re-surveyed using helicopter counts, which are more accurate, but more expensive...
