Greylake () is a
geological Site of Special Scientific Interest,
notified in 1987. This site, on the
Somerset Levels, consists of 20 low-lying fields in the north west corner of
King's Sedgemoor. It includes the
Royal Society for the Protection of Birds' Greylake
nature reserve which has taken over arable farmland and is now home to
northern lapwings,
common snipe,
Eurasian curlews,
redshanks,
yellow wagtails,
skylarks, and
meadow pipits. This location is the type section for the
Pleistocene Burtle Beds, as it is probably the most complete Burtle Beds sequence in Somerset. It demonstrates a sequence of
fluvial (or possibly
glacial) gravels, marine
intertidal silts and marine subtidal. Rich
molluscan,
ostracod, and
foraminifera assemblages and a mammalian fauna, including
red deer (
Cervus elephus),
aurochs (
Bos primigenius), and
fallow deer (
Dama dama) have been recorded. Greylake was flooded during the
winter flooding of 2013–14 on the Somerset Levels. ==References==
