EUTROPHICATION BSAP
ECOLOGICAL OBJECTIVES
i. Concentration of nutrients
close to natural levels
ii. Clear water*
iii. Natural level of algal
blooms
iv. Natural distribution and
occurrence of plants and
animals
v. Natural oxygen levels

INDICATORS
Winter surface
concentrations of
nutirents
Summer Secchi depth*
Chlorophyll α
concentration
Depth range of submerged
vegetation
Area and length of
seasonal oxygen depletion
* The transparency of seawater integrates many of the conrete effects of eutrophication and has
been chosen as the primary ecological objective, other indicators are regarded as supportive
indicators
EUTROPHICATION MSFD
DESCRIPTOR 5
Human induced eutrophication is minimised, especially adverese effects thereof, such as losses in
biodiversity, ecosystem degredation, harmful algal blooms, and oxygen deficiency in bottom waters.
5.1 Nutrient levels
5.2 Direct effects of nutirent
enrichment
5.3 Indirect effects of nutrient
enrichment
Nutrient concentration in the water column
(5.1.1)
Nutrient ratios (silica, nitrogen and
phosphorous), where appropriate (5.1.2)
Chlorofphyll concentration in the water
column (5.2.1)
Water transparaceny related to increase in
suspended algea, where relevant (5.2.2)
Abundance of opportunistic macroalgea
(5.2.3)
Sp. Shift in floristic composition casued by
human activities (5.2.4)
Abundance of pernenial seaweeds and
seagrasses adversely impacted by decreas
in water transparencey (5.3.1)
Dissolved oxygen (5.3.2)

BSAP has much more recommendations for Eutrophication than compared to the
MSFD.
Sweden
• Good Marine Environment Report part 2: Good
Environmental Status (GES) and environmental Standardshave data and information and the next step is the
implemnation of monitoring programs
–
–
–
–
Next step: Define and implement monitoring programs by 2014
Define action programs (Program of Measures) in 2015
Programme of measures intiated in 2016
Achieve GES (first round) by 2020
• The MSFD is actually become a Swedish Marine
Environmental Regulation (law)
• Review of the ecological targets for eutrophication of the
HELCOM BSAP (HELCOM TARGREV)
How can we use this information in
Sweden?
• Race for the Baltic- Summer Campaign 2013
– Policy
• Secure environment ministers application of HELCOM BSAP
• Put pressure to achieve the objectives of sustainable fishing
and especially of cod in BSAP and MSFD
– Campaign
• Ensure the political message of the campaign
• Involve appropriate NGO partners in the region
• Spreading the message of campaign to policy makers and
other contacts in our network
• Helping to organise strategic events
