  We analyse the behaviour of supercritical super-Brownian motion with a
barrier through the pathwise backbone embedding of Berestycki et al. (2011). In
particular, by considering existing results for branching Brownian motion due
to Harris et al. (2006) and Maillard [arxiv:1004.1426], we obtain, with
relative ease, conclusions regarding the growth in the right most point in the
support, analytical properties of the associated one-sided FKPP equation as
well as the distribution of mass on the exit measure associated with the
barrier.
