'''Acaster South Ings'''
==Site location and designation==
Acaster South Ings is a {{convert|38.3|ha|acre}} biological Site of Special Scientific Interest (SSSI),<ref name="Citation" /> consisting of "two large alluvial flood-meadows."<ref>{{cite web |last1=Symons |first1=Bill |title=Biodiversity Action Plan 2013/2014, Table 3 national designations Vale of York |url=http://www.yorkconsort.gov.uk/documents/ycdbbiodivplan.pdf |website=Yorkconsort.gov.uk |publisher=York Consortium of Drainage Boards |date=2014|access-date=12 December 2019 |location=Derwent House, Crockey Hill, York, YO19 4SR |page=13}}</ref> The meadows are adjacent to the [[River Ouse, Yorkshire|River Ouse]] and approximately {{convert|4|mi|km}} south of [[York]].

The SSSI was first [[SSSI notification|notified]] in 1988, and is classified under a wildlife enhancement scheme, due to the presence of [[grassland]]s containing rare plant and insect life.<ref>{{cite web |last1=Simon |first1=Christian |title=Designated sites view: Acaster South Ings SSSI |url=https://designatedsites.naturalengland.org.uk/SiteDetail.aspx?SiteCode=S1004526&SiteName=acaster%20south%20ings&countyCode=&responsiblePerson=&SeaArea=&IFCAArea= |website=Designatedsites.naturalengland.org.uk |publisher=Natural England |access-date=10 December 2019 |date=1 May 1988}}</ref> It is one of nine wildlife SSSIs in the Greater York area, the other designated sites being [[Strensall|Strensall Common]], [[List of Sites of Special Scientific Interest in North Yorkshire|Heslington Tilmire]], [[Askham Bog]], [[Fulford, North Yorkshire|Fulford Ings]], [[List of Sites of Special Scientific Interest in North Yorkshire|Naburn Marsh]], [[List of Sites of Special Scientific Interest in North Yorkshire|Church Ings]], [[Derwent Ings]] and [[River Derwent, Yorkshire|River Derwent]].<ref name="Review of Wildlife" >{{cite web |last1=Hammond |first1=Martin |title=City of York bioversity audit 20107.1.: Review of wildlife sites in the city of York |url=http://democracy.york.gov.uk/documents/s46232/bio%2520Audit%2520Review%25202010%2520with%2520appendices%25203%2520-%2520online%2520only.pdf |website=Democracy.york.co.uk |publisher=City of York Council |access-date=12 December 2019 |page=43 |date=2010}}</ref> It is one of four riverside [[hay|hay meadow]] SSSIs listed by the [[Yorkshire Dales Rivers Trust]], alongside [[Clifton, Rawcliffe and Poppleton Ings|Clifton Ings and Rawlcliffe Meadows]], Fulford Ings and Naburn Marsh.<ref>{{cite web |title=About river and catchment |url=http://www.yorkshiredalesriverstrust.com/your-rivers/river-ouse/ |website=Yorkshire Dales Rivers Trust |access-date=12 December 2019 |date=2014}}</ref>
==Significant site content==
===Flora===
There are grasses such as [[Sanguisorba officinalis|great burnet]], [[Dactylis glomerata|cock's-foot]], [[Agrostis stolonifera|creeping bent]], [[Alopecurus pratensis|meadow foxtail]], [[Holcus lanatus|Yorkshire fog]] and [[Cynosurus cristatus|crested dog's tail]].<ref name="Citation" />

Flowering plants covering the flood meadow include [[Lathyrus pratensis|meadow vetchling]], [[Leucanthemum vulgare|ox eye daisy]], [[Rumex acetosa|common sorrel]], [[Trifolium pratense|red clover]], [[Cirsium arvense|creeping thistle]], [[Filipendula ulmaria|meadowsweet]], [[Plantago lanceolata|ribwort plantain]] and [[Ranunculus acris|meadow buttercup]]. There are "distinct stands throughout the grassland" of [[Polygonum bistorta|common bistort]], and some areas which contain [[Thalictrum flavum|common meadow rue]], and [[Silaum silaus|pepper saxifrage]].<ref name="Citation" />

The site is protected, by earth [[levee|dykes]], from potential flooding from the adjacent River Ouse. These dykes provide plant habitat which is drier than the flood meadows. Some plants which prefer this drier habitat are [[Geranium pratense|meadow cranesbill]], [[Cerastium arvense|field mouse ear]] and [[Campanula glomerata|clustered bellflower]]. Along the riverside are trees and shrubs such as [[Salix viminalis|osier]] and [[Crataegus monogyna|hawthorn]], and plants taller than those in the meadows, including [[Tanacetum vulgare|tansy]], [[Petasites hybridus|butterbur]], [[Artemisia vulgaris|common mugwort]], [[Phalaris arundinacea|reed canary grass]] and [[Epilobium hirsutum|great willowherb]].<ref name="Citation" />

===Fauna===
There are two beetles which are protected here. The rare [[tansy beetle]]<ref>{{cite web |url=https://data.nbn.org.uk/Taxa/NBNSYS0000011153 |title=Chrysolina graminis (Linnaeus, 1758) [Tansy Beetle] |publisher=Nationally Biodiversity Network |date=2012–2013 |access-date=January 20, 2020}}</ref> feeds on the leaves of the tansy plant, and ''[[Aphthona nigriceps]]'' (a [[Aphthona|flea beetle]]) lives on meadow cranesbill.<ref name="Citation" />{{refn|An image of ''Aphthona nigriceps'' can be seen [https://content.eol.org/data/media/81/78/00/542.8851238187.jpg here], and a description of it is [https://www.coleoptera.org.uk/species/aphthona-nigriceps here].|group=nb}} Other insects here are scarab beetle ''[[Hoplia philanthus]]'', [[Rhagonycha fulva|red soldier beetle]], [[Brassicogethes aeneus|pollen beetle]] and plant bug ''[[Leptoterna flavilabris]]''. The [[Eurasian curlew|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.<ref name="Citation" />{{refn|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.|group=nb}}

==Maintenance==
"Active management" is required, to conserve the above flora and fauna.<ref name="Management" >{{cite web |title=Views about management |url=https://designatedsites.naturalengland.org.uk/PDFsForWeb/VAM/1004526.pdf |website=Designated sites Natural England |publisher=Natural England |access-date=12 December 2019 |date=1988}}</ref> Farming practices for the protection of the above species are: "continuation of traditional management for [[hay|haycropping]] followed by aftermath grazing in late summer to early autumn."<ref name="Citation" /> 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 [[Seed|set seed]]. Grazing animals are removed in autumn. There is "regular and careful maintenance of surface drainage including ditches and drains."<ref name="Management" /> The condition of the site is described by [[Natural England]] as "unfavourable - recovering."<ref>{{cite web |title=Designated sites view: Acaster South Ings SSSI |url=https://designatedsites.naturalengland.org.uk/SiteUnitList.aspx?SiteCode=S1004526&SiteName=acaster%20south%20ings&countyCode=&responsiblePerson=&unitId=&SeaArea=&IFCAArea= |website=Designated sites Natural England |publisher=Natural England |access-date=12 December 2019 |date=1988}}</ref> The unfavourable condition was specified as "unfavourable [[Real estate development|development]]" in [[Hansard]] in 2004.<ref>{{cite web |title=Hansard: Sites of Special Scientific Interest |url=https://publications.parliament.uk/pa/cm200304/cmhansrd/vo040901/text/40901w38.htm |website=www.parliament.uk |publisher=House of Commons and House of Lords |access-date=12 December 2019 |date=1 September 2004}}</ref>
==Development and risk assessment==
In 2018 the company Renewables First assessed the area for potential effects of the proposed [[Naburn]] [[Weir]] [[Hydroelectricity|Hydroelectric]] Project. The assessment document concluded that the development was "not expected to have an adverse impact on the nearby SSSIs."<ref>{{cite web |last1=Clutterbuck |first1=Kelly |title=Naburn Weir Hydroelectric Project.
