The small and medium-sized fields around the lake are generally bounded by hedges and occasionally by tree belts and woodland, some of which date back to the most evident period of enclosure of earlier open fields which took place in the late medieval period. Mature oak ("Quercus") and ash ("Fraxinus excelsior") trees are characteristic of the area with occasional groups of Scots pine ("Pinus sylvestris") and chestnuts ("Castanea sativa"). Many elm ("Ulmus") trees have been lost in this area, and dead/dying elms are also evident in the surrounding landscape.
