The Bryophyte flora of the anthills at Old Hall Marshes Acknowledgements I would like to thank Tim Pyner for his tuition sessions and checking many of my specimens, Ken Adams for his comments on this article and lastly to the RSPB for allowing me access to Old Hall Marshes reserve to carry out this survey. A big thank you is due to the staff, Chris Tyas and Paul Charlton, for their help and assistance and for making up and installing marker posts. The maps have been produced using Alan Morton's DMAP software. References BLOCKEEL, T.L. & LONG, D.C. (1998) A Check-list and Census Catalogue of British and Irish Bryophytes.
