The Rare Red Alga Anotrichium barbatum: UK Species Action Plan and its Implementation (1998 - 1999)

The marine red alga Anotrichium barbatum is one of two rare seaweeds in the UK with a Species Action Plan. The alga was detected in Tremadog Bay in 1998. The site was resurveyed in 1999 and Anotrichium barbatum was again recorded. The dataset contains information on the geographical distribution of the alga and density estimates. In 1997 an Action Plan was prepared for English Nature, but downgraded to a Species Statement because there were no known extant UK populations. The discovery of Anotrichium barbatum in Cardigan Bay in 1998 permitted the completion in 1998 of the Action Plan with target. The minimum objective is to stabilize the species' status i.e. to maintain the net population size and distribution against baseline figures set at the time of Action Plan publication.

Data was collected using Standard Marine Nature Conservation Review (MNCR) Phase 2 survey habitat recording techniques. There is a high confidence in this dataset. The alga was detected in Tremadog Bay in 1998 using standard MNCR Phase 2 survey methodology (Hiscock 1996). The site was resurveyed in 1999 and Anotrichium barbatum was again recorded. The only data associated with this project is held within Marine Recorder as Reference No. JNCCMNCR40000738.
