Data Collection (field)

The ABL has experience with multiple types of field sampling. We are familiar with protocols for sampling algae, fish, and macroinvertebrates, and with protocols for in-stream and riparian habitat assessment. For a given project, our staff can collect at sites previously determined by the client, or work with the client to develop a biological monitoring program that will effectively address questions. These questions vary at the scale of point source, whole stream, or entire watershed. They also vary at the periodicity of one-time sampling or long term monitoring.
