Heswall Dales Local Nature Reserve

Alan Irving (Reserve Manager for Cleaver Heath) recently wrote an article about Heswall Dales for RECORD to put in their newsletter.

Heswall Dales

Heswall Dales Local Nature Reserve (LNR) is owned and managed by Wirral Borough Council and forms part of the Heswall Dales SSSI (Site of Specific Scientific Interest). Access is from Oldfield Road, Heswall CH60 6SN (SJ 2595 8242) where there is a notice about both Heswall Dales LNR and Dale Farm. The nearest parking is on Oldfield Road itself. The Friends of Heswall Dales website contains information about what can been seen there. You can find maps both for locating the reserve and for navigating the main paths. Look particularly at the ‘Your Visit’ page where there is a season-by-season guide to flora and fauna.

The main Dales LNR occupies 70 acres of which some 50 are classified as lowland heath. It overlooks the Dee Estuary and is popular with local residents, particularly dog-walkers, who are encouraged to stick to the main paths. Thus there is quite a lot of undisturbed habitat for recording purposes which, conversely, means access to the dedicated recorder can be quite challenging, requiring stout footwear and thorn-proof clothing. As well as attractive heather, Western gorse (Ulex galli) and Bilberry (Vaccinium myrtillus) panels, there are sandstone outcrops, dense scrub areas and birch/oak woodland. The Council web page also contains a copy of the Dales Management Plan. Amongst other things, this contains an overview of the physical characteristics of the Dales and the SSSI citation.

Botanical surveying taking place at Heswall Dales

Botanical surveys of the SSSI are conducted on a 10-year cycle, the last one of which was in 2020. In these, non-plant species are not systematically recorded but only as occasional observations. A small area near the Bush Way entrance (south-east corner) is designated as a Site of Biological Importance.

Complete species bird counts over a fixed route along the main paths have been conducted throughout 2020, yielding some 50+ species. These have been logged using the BTO BirdTrack system. In the breeding season there is plenty of activity by the visiting warblers, and in the winter, Woodcock (Scolopax rusticola) are known to be hiding out and are occasionally flushed during conservation work. Various raptors are found all year round including Sparrowhawks (Accipiter nisus), Tawny owls (Strix aluco), Kestrels (Falco tinnunculus) and Buzzards (Buteo buteo), which make use of the healthy small mammal populations. Other mammals known to be present are Red foxes (Vulpes vulpes), Badgers (Meles meles) and bats about which little is known. Local birders fondly remember the Dartford warbler (Curruca undata) found once in the Dales leading to traffic jams in Heswall, so one never knows what might show up.

Views of heathland and woodland at Heswall Dales

It is not well known how much other recording has been done historically, so there is plenty of scope for further work. We are particularly keen to find out more about invertebrates of all kinds, including butterflies, moths and beetles. The heather is thought to be rich in spider species and merits a proper survey.

For more information about the latest state of recording and further local advice, check with the Friends of Heswall Dales (see their website for contact details) and the Ranger

The reserve is open 24/7 all year round.
