Ash Dieback Survey

The Ash Dieback survey has now started, and will be running until late 2016. Further details are available on the poster and on the BRC website at http://www.brc.ac.uk/splash/.

The objective is to collect quantitative information on the patterns of ash-associated lichen, bryophyte and plant biodiversity in Britain. This is to be done by a structured survey, coordinated by the Centre for Ecology and Hydrology (CEH) and involving volunteers from BLS, the British Bryological Society (BBS) and the Botanical Society of Britain and Ireland (BSBI). We hope that this approach will encourage lichen, bryophyte and plant recorders to work together in the field. The data collected will enable us to obtain robust estimates of the host-specificity of epiphytic lichen species, and so to estimate the extinction risks from ash dieback to epiphytic lichens and the ground flora  at different geographic scales.

Recorders needed! Please email ash-survey@ceh.ac.uk to reserve your sampling squares.

This is part of a wider DEFRA funded project to investigate new approaches to biological recording, which is being led by the Centre for Ecology and Hydrology and involves a range of national societies and recording schemes.

 

Lichens on Ash

Several other studies have been carried out, using the records already held in the BLS database to determine which lichens occur as epiphytes on ash and which might be most at risk if there is high mortality of ash trees. A summary can be found on the Conservation pages, and the posters that were on display at the 2014 AGM can be downloaded below.
