If you go down to the Eyebrook today..

The Eyebrook Reservoir draw-down zone.
... you're sure of a lovely surprise! Botanically speaking, that is. Although it is rather small, it is significant.

During the last vascular plant field meeting this year at Eyebrook Reservoir, the eagle-eyed botanists Louise Marsh and Uta Hamzaoui found some plants of Frog Rush (Juncus ranarius) lurking in the upper regions of the draw-down zone.

A diminutive species, this is only the second confirmed record for this species in the county, following on from Andy Lear's find in 2011 at Rutland Water. It is similar to Toad Rush (Juncus bufonius), but has rounded to emargintae inner tepals and a capsule with a truncate apex, as long as the inner tepals.

Juncus ranarius
Dr Tom Cope, who works at the Royal Botanic Gardens, Kew and who is the referee for this group of  rushes, says: "The species seems to be on the march across the country.  At one time it was strictly coastal (apart from a few records from highly basic soils) but now it seems to be spreading, probably as the result of the salting of roads in winter, and there is a growing number of inland records for it."

So, another seaside plant that we can expect to find in VC55 to add to the growing list of coastal species that are being recorded on salted roadside. No need to take a trip to Skegness any more, the coast (well, its vegetation at least) is coming to us.

Peter Stroh (Cambridge Botanic Garden) recently told me that Sea Barley (Hordeum marinum) has been recorded in Northants (VC32). And I have heard tales of Thrift (Armeria maritima) being found inland on roadsides...

So, keep looking and expect the unexpected. You never know what you might find.

First Bryophyte Field Meeting

It is time to look at bryophytes again and there will be a meeting on Saturday 26th September at Rutland Water to record bryophytes on the drawdown zone and other wet habitats in the Egleton area. The meeting will start at 10 a.m. outdoors and then use the facilities at the new Volunteer Training Centre from about 1 p.m. to 3 p.m. approx., so that we can have a closer look at the specimens using hand lenses, microscopes and books. The meeting is open for everyone with an interest in bryophytes, with a focus on recording and learning together.

Atrichum undulatum
Apart from weatherproof clothes (Wellington boots might be necessary), it is useful to bring a hand lens (x10 or x20) and some paper packets or small containers for collecting specimens. The BBS field guide (Mosses and Liverworts of Britain and Ireland: a Field-guide 2010) is very useful, - the field key can be downloaded from the internet. Please let me know if you would like to take part in the indoor session by contacting me via email or phone (07852 682 790). I will send a further email regarding the exact meeting place and parking.

There will be more bryophyte meetings later in winter. Here are the dates for your diaries: 30th January, 27th February and 26th March 2016. I will sent out emails with more details once they are sorted out.


I look forward to seeing many of you at Rutland Water.
