Hill Hook Nature Reserve - Sutton Coldfield

Hill Hook Local Nature Reserve

Hill Hook Local Nature Reserve - A hidden oasis among residential streets

Hill Hook Local Nature Reserve is located in Four Oaks, Sutton Coldfield, Birmingham, not far from Sutton Park. This hidden oasis of green, bordered by residential streets, is an outstanding site with a wide variety of habitats ranging from grassland, scrub and dry woodland to open water, marsh and alder carr woodland. This provides habitat for a wide variety of plants and animals.

The site has a fascinating history. The large pool originally provided water to Hill Hook Corn Mill, which operated from the mid 1600's, and was sadly demolished in the 1970's. The Mill Pool now provides the focal point for the 7.7 hectors reserve. More information about the history of the mill and the surrounding area can be found at http://www.hillhooklnr.org/index.php

The site is owned by Birmingham City Council and managed jointly by them, The Birmingham & Black Country Wildlife Trust and the Friends of Hill Hook Local Nature Reserve.

Please note - there is no fishing allowed on the reserve.

Wildlife and Vegetation

Hill Hook LNR is made up of a very good variety of habitats with the Mill Pool, marginal vegetation, streams, wet Alder and Willow woodland and marsh, through to hedgerows, established and regenerating broadleaved woodland, scattered scrub and meadow.

The whole site is a very attractive and valuable setting which acts as a green corridor for wildlife extending from the border of South Staffordshire countryside through the residential area into the north of Birmingham.

The varied and rare flora includes wetland species such as Lesser Reedmace, Greater Tussock Sedge and Marsh Cinquefoil as well as established woodland indicator species with Bluebell, Yellow Archangel, Wood Anemone, Moschatel and Opposite Leaved Golden-Saxifrage. Meadow plants are represented by Common Spotted-Orchid, Cowslip and many others.

The vegetation around the Mill Pool has good botanical interest, here Lesser Spearwort, Pink Purslane and Marsh Cinquefoil can be found. The wet Alder woodland has a good understory, with Guelder Rose, Dog Rose, Rowan and Holly, the waterlogged areas are often dominated by Water Horsetail, Sedges and Ferns. In the drier areas the flora is typical of local woodland with Bluebell, Foxglove, Bramble, Hedge Garlic and Ivy.

The Mill Pool is a great attraction to wildlife. There are plenty of large Carp which can be seen as they roll at the surface. Amphibians including Frogs and Common Toads, along with a host of invertebrates such as Dragonflies and Damselflies, make the pool and its edges their home.

Many bird species either breed or overwinter on the reserve. Of the waterfowl Mallard, Coot, Moorhen, Mute Swan, Pochard, Goosander, Great Crested Grebe, Tufted Duck, Canada Geese and Greylag Geese are regularly seen. Woodland birds include, amongst many, Robin, Blackbird, Song Thrush, Wren, Blue Tit, Great Tit, Long Tailed Tit, Greater Spotted Woodpecker, Lesser Spotted Woodpecker, Treecreeper, Nuthatch and Tawny Owl.

The regenerating woodland provides good habitat for Whitethroat, Chiffchaff, Willow Warbler and Blackcap. Swallows, House Martins, Sand Martins and Swifts feed over the Mill Pool in the Summer and Winter visitors such as Waxwings have been seen. Grey Wagtails nest along the banks of the stream running from the Mill Pool.

The area to the north of Hill Hook Road has regenerating woodland and meadow. Summer is the best time to see the meadow flowers, butterflies and other invertebrates such as dragonflies, damselflies, hover flies and bee.

Spring is a great time to visit to see woodland flowers such as Wood Anemones and Bluebells, when the Nature Reserve is alive with bird song.

    This was noticed on the last volunteer day on Saturday 20th and to our surprise had happened quickly. This is no doubt due to the recent hot weather and low water flows. On the 20th some of the algal growth was dragged towards the weir and hence flowed out of the mill pool, also the wind helped to move it and higher water flows were helping to disperse it. With further rainfall this should help restrict the algal growth. However no fish were harmed and none were seen in distress from low oxegen which can occur in hot weather. Earlier in spring, there was a noticeable covering across the pool of a yellow coloured scheen which some people thought could be pollution, however this was in fact pollen from the willow trees.
