Baltic Sea Action Plan

Ecological objectives

– restoring and maintaining sea floor integrity at a level that safeguards the functions of the ecosystems

Name Surname 5/7/2015 2

Marine Strategy Framework Directive

• Sea-floor integrity is at a level that ensures

that the structure and functions of the ecosystems are safeguarded and benthic ecosystems, in particular, are not adversely affected.

Qualitative descriptors for determining good environmental status

Cumulative impact on benthic biotopes

Name Surname 5/7/2015 4

HELCOM pre-core indicator No GES-boundary has yet been set for the cumulative impact on benthic biotopes.

The GES-boundary for cumulative impact on a benthic biotope is assumed to include at most 15% of the biotope area being significantly impacted. The EU Habitats Directive classifies a biotope as being in ‘unfavourable – bad status’ when more than 25% of the biotope area has been significantly impacted.

• Dredging and disposal of dredged material
• Marine constructions
• Exploitation of mineral resources

Guidelines

adopted the following the following documents:

Guidelines for the Disposal of Dredged Spoils may facilitate the assessment of potential hazards caused by dumping of dredged spoils in the Convention area, thus preventing environmental damage

that any deposit into the maritime area of dredged materials, independently of whether it is considered as “dumping” or “placement” within the Helsinki Convention (cf. Article 2, Paragraph 4. a) and Article 2, Paragraph 4. b) ii), respectively), should be assessed on a case-by-case basis in order to ensure that it complies with the objectives of the Convention, Recommendation 13/1 (old version) Recommendation 36/21 (new version)

Quality assurance issues – old data

Data quality analysis, carried out by the Secretariat during 2014, revieled multiple dredging points on land. The reason is FALSE coordinates!!!

Spatial data should have coordinates in decimal degrees Coordinate system as recommended (WGS84) If the other coordinate system was used it must be indicated in the metadata.

Quality assurance issues – old data

Data reported in word documents or scanned maps are not accaptable.

Latest reporting

The latest reported data covers the year 2013 and has been received from Denmark, Germany, Finland and Sweden.

Latest reporting

• Latest reporting (2013 data) was submitted during 2014-

2015.

– old reporting format was still partly used, although new was approved by HOD

• There was also variety in providing spatial data: either points

in excel, MapInfo tab or shapefile

Country Reporting format Point/Polygon (data format) Denmark New Polygon (MapInfo) Finland Old Point (Excel table) Germany Old Point (Excel table + shapefile) Lithuania New Point (Excel table) Sweden New Point (Excel table + shapefile)

New format: Excel sheet and Shapefile

• Deposit site code to link amounts to an area

Ways forward

• To ensure quality of the reported data;

– New Reporting Format should be used. – Point features can be submitted in a table format Decimal degrees XX.XXXXXX, YY.YYYYYY to avoid possible misinterpretation of coordinates. – For polygon areas, reporting format should be ESRI shapefile or compatible (e.g. MapInfo). – Coordinates should be given in WGS84. – Reporting of polygons is highly recommended to achieve better spatial accuracy of the dumping site.

• Please submit your data to the HELCOM

Secretariat HELCOM.Secretariat@helcom.fi by 1 October of the year following the dredging

• activity. It is intended that HELCOM

Secretariat will combine the information to a database and will make it available online via HELCOM website.
