Oak Spinney Park Wetlands |
Oak Spinney Park is a 10 acre factory and office development completed in 2001. The initial site design included a balancing lagoon. Kirby Fields Brook was diverted as part of the works.
In 2005 pollution was noted in Kirby Fields Brook and lining the basins proved an unsuccessful exercise.
DSA were engaged to help tackle this issue. A series of 'leets' (deepened channels) were created to raise the water level. These were planted with a range of fast growing marginal and aquatic species, such as;
Emergents and marginals - Carex nigra (Common Sedge), Iris pseudoacorus (Yellow Flag) and Typha latifolia (Giant Reedmace).
Submerged plants - Callatriche palustris (Water Starwort) and Hippuris vulgaris (Mare's Tail).
Floating plants - Glyceria fluitans (Floating Sweet Grass), Hyirocharis morsus-rana (Frogbit) and Potomogeton natans (Broad-leaved Pondweed).
Water quality has improved dramatically, with concomitant improvements in biodiversity.
