A necessary and sufficient condition for the almost sure existence of the exact packing measure on the boundary of a GaltonWatson tree is obtained with an explicit exact packing measure. In the case where the exact packing measure does not exist almost surely, a criterion which classifies functions
according to whether the
packing measure is zero or infinity is given.
