Acaster South Ings is a

tansy
plant.

Site location and designation

Acaster South Ings is a 38.3 hectares (95 acres) biological Site of Special Scientific Interest (SSSI),[1] consisting of "two large alluvial flood-meadows."[2] The meadows are adjacent to the River Ouse and approximately 4 miles (6.4 km) south of York. Such wet grasslands are considered rare in the United Kingdom due to contemporary "drainage and agricultural improvement."[1][3] The site is accessed on foot via a public footpath along the Ouse riverbank, from Acaster Malbis via Acaster Marine.[4]

The SSSI was first

notified in 1988, and is classified under a wildlife enhancement scheme, due to the presence of grasslands containing rare plant and insect life.[5] It is one of nine wildlife SSSIs in the Greater York area, the other designated sites being Strensall Common, Heslington Tilmire, Askham Bog, Fulford Ings, Naburn Marsh, Church Ings, Derwent Ings and River Derwent.[6] It is one of four riverside hay meadow SSSIs listed by the Yorkshire Dales Rivers Trust, alongside Clifton Ings and Rawlcliffe Meadows, Fulford Ings and Naburn Marsh.[7]

Fauna

There are two beetles which are protected here. The rare tansy beetle[8] feeds on the leaves of the tansy plant, and Aphthona nigriceps (a flea beetle) lives on meadow cranesbill.[1][nb 1] Other insects here are scarab beetle Hoplia philanthus, red soldier beetle, pollen beetle and plant bug Leptoterna flavilabris. The curlew, a wading bird, breeds here. This is "one of few suitable breeding areas for waders" in the Vale of York, so dog walkers are advised to keep dogs on leads during the spring breeding season.[1][nb 2]

Maintenance

"Active management" is required, to conserve the above flora and fauna.[9] Farming practices for the protection of the above species are: "continuation of traditional management for haycropping followed by aftermath grazing in late summer to early autumn."[1] To prevent tall growth and to avoid build-up of decayed vegetation, the fields are cut or mowed in early July after the curlews have bred and the protected plants have set seed. Grazing animals are removed in autumn. There is "regular and careful maintenance of surface drainage including ditches and drains."[9] The condition of the site is described by Natural England as "unfavourable - recovering."[10] The unfavourable condition was specified as "unfavourable development" in Hansard in 2004.[11]

Development and risk assessment

In 2018 the company Renewables First assessed the area for potential effects of the proposed Naburn Weir Hydroelectric Project. The assessment document concluded that the development was "not expected to have an adverse impact on the nearby SSSIs."[12]

Notes

  1. ^ An image of Aphthona nigriceps can be seen here, and a description of it is here.
  2. ^ Natural England's notice on the site's entrance gate requests visitors to keep dogs on the lead, and to keep to the footpath on the dyke along the riverside.
