the act implements the so-called "right to roam" (also known as "jus spatiandi") long sought by the ramblers' association and its predecessors, on certain upland and uncultivated areas of england and wales. this element of the act was implemented in stages as conclusive maps of different regions were produced. the act refers to areas of 'mountain, moor, heath and down' in addition to registered common land; not all uncultivated land is covered.
