A variety of tree types are used by state agencies depending on availability. Click here for map of states that used this method. Structures can be colonized by periphyton, a food source for macroinvertebrates.
Structures are prone to snagging tackle.
Due to lure loss, angler use may decrease. Trees placed vertical in the water column may be more effective for longer periods of time than those lying horizontal. One solution for limiting snags is tying multiple trees together in the vertical position forming rows of trees. This allows fisherman to cast between rows and avoid snagging. If suspended off the bottom, problems with siltation or fluctuating water levels can be minimized.
