It's that time of year when we finally have a chance to write up all our botanical finds from 2013 and share them with friends. So I was delighted to hear from Dr Mary Dean, Lecturer in Biology and Associate Researcher at Edge Hill University, about some fieldwork that she and colleagues - headed by Phil Smith - carried out this year on one of our most photogenic wild flowers, Grass-of-Parnassus
Mary says "Grass-of-Parnassus
(Parnassia palustris) is one of our
most attractive dune slack plants. It is a fairly common plant in Scotland and
parts of Northern England and Wales, although
its range in southern England
has declined recently. It is found along the extensive dune system of the Sefton Coast in South Lancashire (VC59).
conjunction with Merseyside BioBank, a survey of Parnassia palustris took place on the Sefton Coast
in August/September 2013. Phil Smith organised the surveys and
recruited forty-three volunteers to help with surveying to cover all the likely
slack habitat in the sand-dune system.
"Data collected included number of
flowering plants, area occupied, grid reference for each colony and a
range of standard habitat variables. In addition, experienced botanists
recorded quadrats in representative Parnassia
habitat using National Vegetation Classification methodology and took soil samples for pH determination".
Pretty impressive to get 43 volunteers out surveying Parnassia, but anyone who has read BSBI News will have noticed that there is a lot of botanical activity in the Sefton/Birkdale area - botanists as well as plants.
I suspect that courses like the excellent MSc in Conservation Management at Edge Hill play a huge part in this. And it means that if you are visiting the area, there are lots of friendly local botanists who can advise you on where to go. In the nicest possible way!
Mary sent me the photos on this page (taken by Phil Smith) and has these results to report so far from their survey work: "Over 42,000
plants were counted, although it seems to have been a poor year for this
species, due to prolonged deep flooding of the slacks from autumn to
spring in 2012/13. Pat Lockwood [image above] can be seen counting the plants on the Birkdale Green Beach".

She continues " I surveyed slacks on the Ravenmeols Local Nature Reserve and found a couple of cream-flowered plants. Phil Smith had recorded
cream-flowered plants in this slack in 2004 and it is good to see that they or
their offspring are still there".
Mary tells me that Phil Smith (possibly with Pat Lockwood) will be preparing a report on their survey work and they hope to publish in 2014. In the meantime, I'm putting "Visit Sefton again" into next year's diary.
