Macroinvertebrate samples are collected with a D-frame kick net by scrubbing rocks and stirring up the creek bed in front of the net. This dislodges the macroinvertebrates so that the current can carry them into the net. This is labor intensive fieldwork, and it can take up to six hours to complete a survey.
