This article is a short introduction to super-Brownian motion. Some of
its properties are discussed but our main objective is to describe a
number of limit theorems which show super-Brownian motion is a
universal limit for rescaled spatial stochastic systems at criticality
above a critical dimenson. These systems include the voter model, the
contact process and critical oriented percolation.
