Hay Head Wood is an area of mixed woodlands, grassland, scrub, marsh, and open water of an old canal basin. The derelict site of hay Head Lime Works is situated within the boundary. Aspen and alders line the banks of the disused canal, while around the marshy portion willow and sallow occur. Oak, ash, alder and sycamore grow in the better drained slopes. Floral species include bluebell, wild garlic, wood anemones, wood sorrel, and yellow archangel, which grow in direr areas and more open inundated ground supports marsh marigolds, meadowsweet and Hymalayan balsam. Reedmace, water dock and yellow flag iris grow in the old canal basin itself where moorhen are able to use the cover for nesting. The waters support perch, pike and roach.
Scrubby areas of the site are favoured by such birds as blackcap, bluetits and yellowhammer.
Create small woodland clearings to diversify age structures in areas where sycamore and hawthorn are overgrown and cast dense shade.
Clear marsh and open water of canal where necessary. Construct rides and footpaths and fence where access is poor or the habitat is liable to damage by trampling of the public or cattle on surrounding land.
