Only the second record for Cheshire, but looking well established.
No interactions present.
As far as birdwatching goes, the Carrington Moss area (where the last few sightings have been located) is in Greater Manchester not Cheshire.
Do plants have different county boundaries? :)
... has used vice-counties, which are the counties of a particular date, but with the bigger ones broken into two parts (and the 3 Yorkshire ridings into 5 parts in toto). This applies to birds as well as to plants.
[This give me a slight problem, as the nearby current county boundary doesn't follow the exact same line as the vice-county boundary for a mile or so, and I don't know exactly where the vice-county boundary runs. In part it follows a stream, but the stream isn't there anymore.]
Floristicians and faunisticians have continued to use these regions for recording so that records of different eras are comparable. Some organisations might still be using vice-counties for birds.
Nowadays finer grained recording - hectads (100km^2), tetrads (4km^2) and monads (1km^2) - is used, and for plants the principle use of the vice-county is to define patches for the BSBI's county recorders.
... by a church carpark, with a single plant. But there's obviously been a wild-flower seed mixture sown in the area, so I'm agonising over whether it is recordable.
If it exists in the area you're recording, then I would record it, but make a note that you believe it to be planted. (I put a small P on my recording card).
I think it is good to just be scientific and put what you see and not to make a judgement on what is worthy of a record or not.
I have been recording locally and recently there has been an import of really sandy top soil in our country park, and all sorts of sea side plants have appeared. They have also sown a wild flower mix on a perimeter bank in an area of grassland that they now use for weddings.
I'm pretty sure that most won't survive, but would like to think that if these oddities do make it then at least there is a record of when and how they arrived.
