Comment:
The 2016 family of four cygnets are seen
with 'mum' at the north end of Urswick Tarn. One pair of adult
swans are continuing to breed successfully on this marl tarn each
year despite the dramatic and, as yet, unexplained decline of
other species of water fowl, most significant of which
is the coot. The tarn has been nominally owned by Urswick Parish
Council, on behalf of parishioners, since 1 September 1948 when it
was purchased from The Holker Estate Company on the first part, Richard Edward Osborne
Cavendish of the second part, and Chatsworth Estates Company of the
third part, for £250. Now unseen at the bottom of this tarn is
a deep deposit of haematite effluent sediments which were permitted
to be brought via a constructed drain from the haematite mines
around Lindal in Furness during the second half of the nineteenth
century. Investigations relating to toxins in those sediments
continues.
