In this paper, first steps are taken towards characterising lattices of cyclic flats Z(M) that belong to matroids M that can be represented over a prescribed finite field \mathbbFq. Two natural maps from Z(M) to the lattice of cyclic flats of a minor of M are given. Binary matroids are characterised via their lattice of cyclic flats. It is shown that the lattice of cyclic flats of a simple binary matroid without isthmuses is atomic.
