PLANT RECORDING IN 2002 MARTIN SANFORD A lot of good recording was carried out in 2002 with several groups of recorders covering new tetrads and turning up interesting finds. The map of tetrads with less than 100 species at the end of 2002 shows that we are making good progress towards getting all squares covered and the efforts of recorders in the Sudbury and Southwold areas clearly show how well they have done in picking up under-recorded areas. Many of the tetrads on the borders and coast have only tiny areas within Suffolk but there is still a fair number of squares in the ‘arable prairie’ parts of Suffolk that need recording. Less than 100 species at end of 2002

Yet again the Norfolk team have been very active, managing to visit 26 tetrads twice and another six once. They all have to travel a lot further in order to reach new areas and their efforts are much appreciated. They have obviously ‘got their eye in’ for some of the arable weed species and have made a significant change to the map for Cornfield Knotgrass Polygonum rurivagum with records from Stonham Parva, Pakenham, Great Barton, Debenham, Aspall and Stanton. This annual species is an overlooked weed on calcareous soils which is not easy to distinguish from the common P aviculare. The map in the New Atlas (Preston, Pearman & Dines, 2002) shows how well Norfolk has been covered compared with the rest of the country.
