The reservoir embankments are home to a wide variety of wild flowers and are a good example of an unimproved grassland habitat. Such habitats are getting very scarce, as most grasslands used for agricultural purposes are improved by adding chemical fertilisers which promote the growth of grass, but these coarse grasses then out-compete and choke the wild-flowers. Fortunately, the grasslands surrounding the reservoir are not treated with chemicals and the wild-flowers flourish, as they did in the hay meadows of earlier times. Many of the plants recorded are typical of such old established meadows and include species such as pignut, quaking grass, yarrow, yellow rattle, common twayblade orchid and early purple orchid.  In fact, five species of orchid have been recorded from the site, and in addition to the above, there is also common spotted orchid, green-winged orchid and bee orchid, although the latter two are uncommon.
