Quadrat used for survey. Consists of a small anchor holding an upright PVC tube (1 m tall) with a smaller tube inside to allow the quadrat to telescope and pivot around this central axis. A 90° joint connects the telescoping base to another PVC tube (1 m) which acts as the radius of the quadrat. Depth measurements are marked on the base to allow easy depth measurement. The anchor is a one-gallon plastic bucket filled with concrete.
