Minimum lvel nonplanar (MLNP) patterns play the role for level planar graphs that the forbidden Kuratowksi subdivisions $K_5$ and $K_3,3$ play for planar graphs. We add two MLNP patterns for trees to the previous set of tree patterns given by Healy $et al.$ . Neither of these patterns match any of the previous patterns. We show that this new set of patterns completely characterizes level planar trees.
