This sandy arable field has been designated an SSSI because of its large population of a nationally endangered plant, red-tipped cudweed. This was formerly a common weed on arable fields, but it has been in sharp decline since the 1960s. The colonies in the site and neighbouring fields may represent as much as 50% of the British population.{{cite web|url= https://designatedsites.naturalengland.org.uk/PDFsForWeb/Citation/1005744.pdf |title=Hankley Farm citation|series= Sites of Special Scientific Interest|publisher=Natural England|access-date= 18 December 2018}}
