BIOMARE PRIMARY SITES: DETAILED QUESTIONNAIRE FORM

Proposer:

Name: Erik Bonsdorff

e-mail address: erik.bonsdorff@abo.fi

Proposed Primary or Reference Site:

Primary site for the Archipelago Sea in the Northern Baltic Sea, Western Åland Islands (at the junction between the Baltic Proper, the Gulf of Bothnia, and the Archipelago Sea & Gulf of Finland).

Total area 24 600 ha (islands and water included), 13 200 ha consisting of water.

 

PRISTINESS: Primary sites should be as free as possible from anthropogenic stressors, and natural stressors atypical of the region (e.g. reduced salinity, high turbidity).

No industry, factories or major water outflow in or close to the region.

List potential sources of pollution that are likely to impinge on the site:-

Industrial pollution: -

Agricultural pollution: fish farming (prod. 80tons/year), average Baltic eutrophication

Mining: -

Dumping: -

Dredging: -

What is the human population of the site in total and per unit area? What is the average population growth per year?

The human population within the area is 520 (1 person/47ha) and the average population growth is ± 0 (usually negative), in 2000 +0.4%

How is sewage disposed of? If possible give an estimate of the quantity and quality of the output.

Municipality dumping ground and recycling stations in the villages.

Describe the extent of commercial fishing in the area. Please specify the kinds of gear used (trawling, seine netting, lobster pots etc.)

5-8 part time fishermen in the area, all fishing with gillnets. Seasonal fishing common, for example pikeperch (Stizosteidon lucioperca) is caught only in spring.

Other species caught for more or less commercial use are whitefish (Coregonus lavaretus), perch (Perca fluviatilis), baltic herring (Clupea harengus), pike (Esox lucius) and flounder (Platichthys flesus).

Give an account of tourist activities in the area (how many tourists per year; what do they do?).

120 small cottages for rent in the area, used mainly in summer by tourists. 4 guesthouses/hotels with 150 beds situated within the area. Tourists use parts of the area for recreational purposes and sport fishing.

Provide evidence that there are no natural stressors such as high turbidity or reduced salinity that are atypical of the region.

No river out flows or other atypical stressors in the region.

Give references to any chemical or physical data that support the claim that this is a pristine site.

HABITATS: The site should comprise a mosaic of habitats in a well-defined area that are representative of the region.

List the range of habitats present at the site:-

Littoral

Rock: Yes

Sand: Yes

Mud: Yes

Sublittoral

Rock: Yes

Sand: Yes

Mud: Yes

Geographically very diverse, ranging from shallow inner bays to outer exposed skerries.

How representative is this site of its region (i.e. what regional habitats are missing)?

No regional habitats are missing in the proposed area

BACKGROUND INFORMATION: The site should already be well-studied (i.e. biodiversity studies should not rely entirely on new research).

For what groups of organisms are comprehensive inventories available? Please list major taxa in each category below, and list publications.

List any other publications relating specifically to the biodiversity or environment at the site.

Reports (in total >300) on biological surveys made at the Husö biological station starting in 1961Ý . Includes international reviewed papers as well as reports for the Åland’s government and administrative board, MSc-thesis and PhD-thesis at Åbo Akademi University.

List publications relating to historical/time-series data at the site.

Reports (in total >200) on biological surveys made at the Husö biological station starting in 1961Ý . Includes both reports for the Åland’s government and administrative board, MSc-thesis and PhD-thesis. Most reports in Swedish with English summary.

Is biodiversity information available in electronic form? If so, what is the nature of the database (CD-ROM, web-site)?

No

PROTECTION STATUS: The pristine nature of the site should be protected by legislation if it is to be a "flagship site" for future monitoring.

What conservation legislation (national, European, international) is currently in place, how well is it implemented and how long will it last?

4 Natura 2000 areas are established in our proposed site. Their total area is 1120 ha.

ADDITIONAL COMMENTS.

Please use this section to add any additional supporting comments, for example what do you think is special about your site from the biodiversity point of view, why is it important to monitor biodiversity there, and what is the public awareness of this?

The government and administrative board of Åland is responsible for monitoring fish occurrences (since 1976) in co-operation with the National Board of Fisheries in Sweden. Two monitoring stations are found in the area. Yearly sampling is performed with gill nets of varying size. All species are analysed (CPUE, length, frequency of diseases). Furthermore eelpout (Zoarces viviparus) is yearly caught to detect environmental stress by studying defects of their fry.

The area is as pristine as possible in the Finnish coastal waters, situated far (>50 km) from any industry or larger community (>1000 pers). Due to Baltic water currents, municipal water from Helsinki, Turku or Stockholm does not directly affect the area. Also the tourist activity is very limited, since the area is remote, inhabited by only two villages. The only known polluter is one small fish farm (prod 80t/y), which likely will be shut down after a few years.
