  The quantum Hall ferromagnet at filling fraction $\nu = 1$ has some unusual
properties due to the remarkable identity between the topological density of a
spin distortion and the associated electrical charge density. We investigate
the localization of spinwaves by coupling to a scalar disorder potential via
their topological density. A low energy description of the system in terms of a
non-linear sigma model of unitary supermatrices is derived. All states of this
model are localized in two dimensions. A possible experimental signature of
these effects in photo-luminescence is suggested.
