Tetrad Hunts

Tetrads for which we want records - any records - even Common Daisy!

 

Explainer: A "tetrad" is a collection of four monads (1km squares) used for recording and mapping of plant locations. Each tetrad starts on an even numbered northing and easting monad and includes the monads north, east and northeast of that square.

These 2km squares are mostly unrecorded - which will mean little gaps in the forthcoming Flora's maps of distribution for plants that are probably present. So no need to search for rarities (but by all means do!) but please let us know if you find anything at all. (This includes Purple Moor-grass and Bracken!)

 

Note that only one 1km square from the list need be recorded but the wider the coverage (recorded by monad) the better.
