Ulmus laevis
There are a variety of mature trees on the site, including field maple, hybrid black poplar and also a rare surviving Flanders elm on the river bank, ( there is a contradictory Wiki page that says that the tree is misidentified and is actually a European White Elm Ulmus laevis ) which bears a Great Trees of London plaque, denoting trees considered of importance to the capital. The northern part of the park features a small nature reserve.
