Log barriers

Simple, stout barriers constructed from thick, straight logs placed on two short, upright posts of similar dimensions and set fairly deeply into the ground are quite effective. Varying the length and direction of barrier sections enables them to be aligned in different ways to follow the outside edges of the parking areas. Solid debarked logs should be used, sufficiently thick to be both physically and visually strong. The wood can be left to weather or can be stained to blend into the landscape, although the logs do need

Log barriers

(a) Poor design of rock barriers: too even in size and spacing, parallel with the bay edge and sitting on the ground. (b) Here the rocks vary in size, spacing and alignment and are partly sunk into the ground.

Log barriers

Horizontal log barriers of large size laid close to the ground are effective and fit into this wooded landscape of large trees.

to remain visible. They should be set at car bumper height, which also makes it difficult to lift a motorcycle over them. If vandalism is a problem the logs can be protected against chainsaws with a wire inlaid along their length on at least two sides.
