Individual sediment cores are then placed in a modified self- cleaning screen (Euliss and Swanson 1989) to concentrate sample residues and placed in specimen jars. We used the described sampling device for two field seasons to collect macroinvertebrates in shallow wetlands. Our study sites contained minimal submergent and emergent vegetation that would interfere with the operation of this device. The sampler withstood rigorous use and required only occasional minor maintenance of the cable used to close the doors. Materials for the sampling device cost about $ Total construction time was about 8 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
