This has been a wet area historically and proved difficult to drain. With time and possibly since the creation of the mainline railway, but caused by recent development (which drain directly into the wetland), it is now a fine wetland full of phragmites, so spp poor, but otherwise functioning as habitat and groundwater recharge area. It is particularly important that the open area to the north is not drained or developed.
