Subsurface sowing of yellow lupin (Lupinus arboreus) for economical and rapid sand dune stabilization at Woodhill Forest

P.J. Berg and C.W. Smithies



Subsurface sowing of yellow lupin (Lupinus arboreus) seed has proved a successful and economical means of rapid sand dune stabilization at Woodhill Forest, North Auckland. On easterly faces, less exposed flats and hollows, and unstabilized patches of bare sand, after subsurface sowing the growth of yellow lupin alone leads to rapid stabilization. In the most exposed situations, planting of marram grass (Ammophila arenaria), in addition to sowing lupin, is advocated. Present methods of subsurface sowing of lupin seed, and the trials leading up to the development of these, are considered.
