This species is rare in <strong>Huntingdonshire</strong> and neighbouring counties. The recent finds in<br />
<strong>Huntingdonshire</strong> mirror similar recent finds elsewhere, <strong>for</strong> example in Northamptonshire and<br />
Cambridgeshire. Is this species recovering lost ground or extending its range?<br />

This is a species <strong>of</strong> fen dykes, river banks, ponds and occasionally wet meadows. It is only<br />
locally distributed within <strong>Huntingdonshire</strong> and is becoming scarce (Wells, 2003). There is an<br />
additional record from a meadow at Ramsey Heights where it has been sown and may not<br />
persist.<br />

Woodwalton Fen SSSI & SAC TL22998486 2011 (MM)<br />
Last recorded in 1846 from Somersham and assumed long since extinct until re-found by MM<br />
in 2008 at Woodwalton Fen. A re-survey in 2011 found 20 plants. Also in 2008, populations <strong>of</strong><br />
purported Oenan<strong>the</strong> silaifolia just over <strong>the</strong> county boundary in Northamptonshire were also reidentified<br />
as this species. As such, <strong>the</strong>re is evidence that <strong>the</strong> two species are not well<br />
understood in <strong>Huntingdonshire</strong> (see also below) and it would not be entirely surprising if<br />
additional populations <strong>of</strong> O. lachenalii were to be found over coming years.
