Lye Valley granted new protective status

The Lye Valley's extraordinary hydrological and geomorphological features – its “Living Geology” – has been recognised by its new protective designation as Local Geology Site by the Oxfordshire Geology Trust:

Vision for the Lye Valley

The FOLV's Vision is to conserve and/or restore the whole of the Lye Valley as a natural continuous green area of land with a mosaic of different wet and dry habitats

The Grass of Parnassus

The fragile and rare Grass of Parnassus, first named by Matthias de L’Obel in 1570 when he found it growing in Hogley Bog (i.e. the Lye Valley), flowered again at the end of August 2014, hidden amid squelchy pools cloudy with tufa. 

Dr Judy Webb has captured the stages of the buds’ unfolding in a series of pictures, from the male stage with anthers folded over stigma and the false nectary staminodes clear, through anthers bending out and opening one at a time stage, to the female stage where the anthers are gone, the ovary turns pink, and the stigmas are now uncovered and receptive to pollen on top of the ovary. Then follows the new seed pod. Characteristically one heart-shaped leaf encircles the stem

It was first noted in this wetland in 1640, but has probably been here since the last Ice Age. The Lye Valley is the most southerly place that the grass is found in England.

Did You Know?

Proportionately there are more rare plants in the Lye Valley than in any other city site – at 20 species this is a third of the 61 species on the County Rare Plants Register found within all the nature sites in and around Oxford that are managed by Oxford City Council.

See our Chair, Dr Judy Webb’s, detailed report on the state of the Lye Valley for the Wild Oxford Project. It’s the ONLY fen (alkaline bog) to show such fast return to its former glory in Oxfordshire.  Formerly there were 10 really good alkaline fens.  Of these, 8 are being lost to natural succession to wet woodland through lack of management. Only Cothill fen and the Lye Valley fen are actually improving, due to having management. The Lye Valley fen – thanks to its volunteers, Oxford City Council, BBOWT, Oxford Conservation Volunteers – and not forgetting the Friends of Lye Valley – is getting better and better!  But it still needs our help and protection.

Read all about it!
