For day VFR and a bush pad, take surveyor's flagging to mark any tall hazards (standing dead trees, etc, which will also act as your wind indicators. Take a rock and wrap more tape around it to mark the spot where you want the pilot to put the toe of the skid if space is tight. If only one dircetion of approach will work, then make sure you have communicated this to the driver and be prepared to marshall the arriving aircraft. A couple of logs laid on the ground at right angles to the desired landing direction, and spaced a little wider than the crosstubes, will aid the pilot in finding the desired spot as well as supporting the machine on soft ground.
In the end all you need is comms, a folding saw, and flagging tape: all very friendly to those traveling on LPCs (Leather Personnel Carriers).
