Extract from a report compiled by Juan Salado Tuero, Licenciado en Ciencias del Mar.

In January 2003, after lengthy debate the States of Alderney formally requested, through its land management committee (the General Services Committee), that the Alderney Wildlife Trust investigate the possibility of a Ramsar Site for Alderney. However, the Committee also stipulated that the States of Alderney would not be prepared to allocate resources for the Ramsar application process until it could be assured that such an application would be successful.

In response the following objectives were identified:

§ Identify the area most suited for Ramsar designation; initial research pointed to the areas around and between Clonque Bay, Hannaine Bay, Les Etacs, Ortac, and Burhou

§ Establish what data is available for that area; it was quickly established that in the past there had been minimal research within this area and as a result little scientific data recorded; with the exception of bird ringing data from Les Etac, Ortac and Burhou, though this data has traditionally been held in Guernsey.

Therefore the Trust undertook to complete a baseline study of the flora and fauna for proposed site in order to get the data required for the JNCC's approval.

To this end Juan Salado Tuero (Licenciado en Ciencias del Mar) was employed by the Trust to complete a baseline study for the Clonque and Hannaine Bay areas.

§ Approach the Joint Nature Conservancy Council with the results of the baseline study.

§ Upon gaining approval from the JNCC, to lobby the States of Alderney for the designation of a Ramsar site.

The Trust commenced the study in July 2003 and is grateful to Bridget Ozanne (Biological Records Centre Officer, Societe Guernesiaise) and Charles David (Vice President, Societe Guernesiaise) who both visited Alderney in late September 2003 to assist in the work. With their expertise it has been possible to classify some invertebrates within this area; however, the survey has so far concentrated largely on identifying algae.

The Trust is also in the process of collecting all ornithological data in relation to the proposed Ramsar site, especially for Burhou, Les Etac and Ortac because of the importance of their bird colonies upon which a future Ramsar application is likely to rest.


To date species lists have been completed as follows:


§ 83 species of Algae

§ 12 Clorophyta

§ 22 Phaeophyta

§ 49 Rhodophyta

§ approximately 15 non classified specimens

§ 15 species of Lichen


No flowering plants have been included in this application, although a very extensive database of these exists, on the part of Alderney, both on and adjacent to, the shore and also of each of the offshore islands and islets within the proposed site. This has been developed over more than 20 years by Brian Bonnard, BSBI (Botanical Society of the British Isles) recorder for Alderney, and was studied by Juan Tuero during his researches.

N.B. 98 Algae and Lichen species have been identified within an estimated 55% of the total Clonque and Hannaine Bay areas.

(See lists of Algae, Invertebrates and birds recorded in the site which follow)


§ 59 species of invertebrates


Initial results strongly support the Trust's belief that the proposed site would qualify for Ramsar status. However, whilst it is likely that the States of Alderney would support a future application, it would seem doubtful that they would be prepared to support the effort to collect the necessary data.

(This proved to be the case and the AWT found, and paid the costs of, the experts involved in the surveys and the preparation of the application.)
