The balance of every rural property's Reserva Legal (Lei 12.651/2012): the share of its area it must keep in native vegetation (art. 12: 80% in the Amazon's forests, 35% in its cerrado, 20% in its campos gerais and the rest of the country; a map of the share, or one for all), its native vegetation counted outside the APPs and, as art. 15 allows, inside them, and its deficit or surplus; the properties of up to 4 fiscal modules on 22 July 2008 keep only the vegetation they had then (art. 67).
