Based on the art. 6 of Regional Law 9/2005 concerning the protection of natural stable meadows, the regional administration codifies the natural stable meadows of the plains in a database, reporting the biological and territorial information, as well as the cadastral data referring to the individual stable meadows. For the purposes of Regional Law 9/2005, stable natural meadows mean the herbaceous formations attributable to the types identified in Annex A of the law itself. In the context of stable natural meadows, as defined by art. 2 of Regional Law 9/2005, the following are included: a) herbaceous formations that grow on land that has not undergone clearing by plowing or harrowing and are maintained only through mowing and possible fertilization; b) herbaceous formations which, although derived from previous cultivation, have the floristic composition of the types listed in Annex A, points A) and C), to this law; c) the practical formations deriving from compensatory interventions and reductions in pristine condition. The stable meadows included in the database may or may not fall within the scope defined by art. 3 of LR 9/2005: meadows effectively protected by LR 9/2005 and which fall within the scope defined by art. 3 of LR 9/2005, constituting the inventory of stable meadows, are characterized by having the field of the TutelaLR database set to "True" (value 1) and are represented in the map in red. The inventory of stable meadows therefore represents a subset of the database.
