Flora Some of the trees in the area are the White Poplar (Populus alba), Hawthorn (Crataegus monogyna), species of wild rose (Rosa spp.), Smoothleaf Elm (Ulmus minor) and Hedge Maple (Acer campestre). The marsh pond has a narrow belt of the reeds round the perimeter such as the Marsh Reed (Phragmites australis) and False Bulrush (Typha latifolia). Some of the plants in the draining channels are Water Cress (Nasturtium officinale), Purple Loosestrife (Lythrum salicaria), Great Willowherb (Epilobium hirsutum), Common Meadow-Rue (Thalictrum flavum) and Yellow Flag (Iris pseudacorus). The recently excavated Education Pond will be gradually colonised by wild marshland species.
