The identification system for agricultural parcels referred to in Article 70 of Regulation (EU) No 1306/2013 shall operate at reference parcel level. A reference parcel shall contain a unit of land representing agricultural area as defined in F1Article 4(1)(e) of Regulation (EU) No 1307/2013 F1Article 2(1)(c) of Regulation (EU) No 1306/2013. Where appropriate, a reference parcel shall also include F2areas as referred to in Article 32(2)(b) of Regulation (EU) No 1307/2013 and agricultural land as referred to in Article 28(2) of Regulation (EU) No 1305/2013.

F3The relevant authority shall delimit the reference parcel in such a way as to ensure that the reference parcel is measurable, enables the unique and unambiguous localisation of each agricultural parcel annually declared and as a principle, is stable in time.

F4The relevant authority shall also ensure that agricultural parcels that are declared are reliably identified. They shall in particular require the aid applications F5and payment claims to be furnished with particular information or accompanied by documents specified by the competent authority that enable each agricultural parcel to be located and measured. For each reference parcel, F6the relevant authority shall:

1. (a)

   F7determine a maximum eligible area for the purpose of the support schemes listed in Annex I to Regulation (EU) No 1307/2013;

2. (b)

   determine a maximum eligible area for the purpose of the area-related measures referred to in Articles 28 to 31 of Regulation (EU) No 1305/2013;

3. (c)

   F8locate and determine the size of those ecological focus areas listed in Article 46(1) of Regulation (EU) No 1307/2013 for which the F9relevant authority has decided that they shall be considered as ecological focus area. For that purpose, F10the relevant authority shall apply the conversion and/or weighting factors set out in Annex X to Regulation (EU) No 1307/2013, where appropriate;

4. (d)
   F11F12determine whether provisions for mountain areas, areas facing significant natural constraints and other areas affected by specific constraints as referred to in Article 32 of Regulation (EU) No 1305/2013, Natura F132000 areas and areas covered by Directive 2000/60/EC of the European Parliament and of the Council14F14... apply
5. (d)

   F12determine whether areas naturally kept in a state suitable for grazing or cultivation as referred to in Article 4(1)(c)(iii) of Regulation (EU) No 1307/2013, F15areas designated by the relevant authority for the regional and/or collective implementation of ecological focus areas in accordance with Article 46(5) and (6) in that regulation and areas covered with permanent grasslands which are environmentally sensitive as referred to in Article 45(1) of that regulation apply.

6. (d)

   F16determine whether areas covered with permanent grassland which are environmentally sensitive as referred to in Article 32A of Regulation No 1307/2013 apply.

F17The relevant authority shall ensure that the maximum eligible area per reference parcel as referred to in paragraph 2(a) is correctly quantified within a margin of maximum 2 %, thereby taking into account the outline and condition of the reference parcel.

For the measures referred to in Article 21(1)(a) and Articles 30 and 34 of Regulation (EU) No 1305/2013, F18the relevant authority may establish appropriate alternative systems to uniquely identify the land subject to support where that land is covered by forest.
