Changes in the status and distribution of Oenanthe pimpinelloides in Essex
I am grateful to Reg Arthur, Rodney and Matthew Cole, Kevin Marsden, Tim Pyner, Graham Smith
and Terri Tarpey for the records quoted above and on the distribution map. It is likely that many
more sites exist in the county that we have yet to find out about, and I would be grateful for
additional records however old, particularly sites where it has appeared recently.
