Hi Gareth.
Not sure if you’ve had help with your dilemma.
I would suggest that all the information you require with regards to the field in question would be on the ownership deeds. Alternatively any Agricultural Estate Agent would help (for a fee) as most normally keep OS Maps and field maps for the area they cover, you obviously know which Parish the field is in and you could help the Agent locate the field on the map.
Field size is exactly that! As declared on the map in Acres and Hectares, nothing to do with diameter.
With regards to ‘moving sheep to tack?’ In our area ‘tack’ is the term we use for ‘sending sheep away to another holding for wintering’.
I’ve no idea about the 3000 number, but when I obtained a temporary holding number, which is what you’ll be given (12 months), mine was an 8000 number (CPH – XX-XXX-8000).
I don’t know your location, but I’m in Mid Wales and I contacted the Welsh Assembly Office at Caernarfon and they were extremely helpful.
http://gov.wales/topics/environmentcountryside/helpandadvice/county-parish-holding-numbers/?lang=enI can understand Animal Health Dept. wanting the information, but I’m not sure why the RPA need the details, maybe I’m wrong, but as you don’t have a CPH for the field, you wouldn’t have declared it on your SAF2015, therefore you will not be getting any payments as a result of grazing the field.
I hope some of the above is of help to you.
