A second Upper Thames record of Light Knot Grass

It was quite a surprise when Richard Ellis found Light Knot Grass in Bucks in 2019. There has now been a further surprise: Simon Van Toller has reported another specimen, from Windsor Great Park in Berkshire on 7 May this year. Not a species I would have predicted as an addition to the Berkshire county list! Light Knot Grass is resident in the north and west of Britain, and as far as I'm aware it is not normally known to show migratory behaviour, which makes the two Upper Thames records something of a mystery.
