5 Shown above is a pipe-steel spear trap. Often 'spears' are made from timber saplings with points axed at 5
the ends.
With this paticular spear trap at the sanctuary, the spears are held up by wires (difficult to see, but are indicated by the 2 arrows) which are supported by a top rail over the gateway. The weight of the spears which are suspended by wires prevents the spears from moving sideways too much.
The brumbies push their way through the spears which will move sideways slightly, but when they try to go out gain, the spear points are against them.

3 At various times brumbies are trapped at the sanctuary.
Shown here is an old trap yard which is located near a dam.
There are various ways to entice brumbies into trap yards.
Enticements used can be water, food such as grassy hay, salt, molasses, or a lure mare. The choice of enticement depends on a number of conditions. For example, water is not a successful enticement when there is plenty of water around.
Once brumbies have entered the trap yard, closing them in can be done by using 'spears' (see example further below), or a trip wire which will trigger the gate closure, or someone can remain hidden and use a long rope to pull the gate closed.
