Primula veris
To the south of the town, between Little Ponton and Saltersford, the River Witham flows through marshes and water meadows that support a variety of plant species, including vetches, cowslip, "Primula veris", Lady's bedstraw {Galium verum}, and orchids, including the Southern Marsh Orchid, and wildlife, including herons, ducks, geese, water vole, and the now critically endangered white clawed crayfish. The area has notable populations of dragonflies, especially "Aeshna grandis", "Anax imperator", "Libellula quadrimaculata" and "Calopteryx splendens", which are also found on Grantham Canal as it runs through The Vale of Belvoir to the west of the town. Wildlife can also be found in the town's Wyndham and Dysart Parks.
