1. A relocated turf surface installed at a destination site, within two days of the relocating, and suitable for use as an athletic playing surface, comprising:
a reinforcing root permeable mat that is sufficiently strong to have supported the turf surface during the relocating and also sufficiently strong to support the turf surface during subsequent use as an athletic playing surface at the destination site, the reinforcing root permeable mat including a plurality of substantially vertical reinforcing fibres;
a layer of growth media located on the reinforcing root permeable mat; and
natural grass plants having roots extending downwardly through the layer of growth media and the reinforcing root permeable mat, wherein the natural grass plants include newly grown roots at a bottom thereof, the newly grown roots having been generated because of the prior removal during harvesting of a root layer that had existed when the turf surface was previously located and created at a grow in site.
