One field - or two?

Years ago, when #onestreet and #onetree were  popular blip themes I tried to introduce another called #onefield. No one else took it up so all the entries are mine.

This was my One Field. Roughly 3 acres, it lies to the north and the east of our house and has a view across to the sea  a kilometre away. Hitherto we have always let it to our neighbour who uses it for grazing and takes a cut or two of grass for silage or haylage off it each year.

On old maps the field was shown divided into several smaller enclosures although there is no sign of them on the ground..
Now, we are going to use a third of the field to plant trees and to install a solar array. So today this new fence has been going up. We will plant a hedge along it.

My problem is, how to refer to the now-partitioned One Field. Large and small? A and B? Far and near? 
(We already have an adjacent Little Field which is also going to be planted.)

There are active setts along the wallbank at the top so one idea I've had is to call it Badger Field, morphing  eventually (we hope) into Badger Wood: Cae mochyn daear/Coed mochyn daear in Welsh.
(Mochyn daear translates as earth pig.)
