17.4.2013Centre for Economic Development, Transport and the Environment in Lapland1 Classification and monitoring of the surface waters of Finland National WFD-monitoring and revised classification of ecological status
2
Quality elements Biology: Algae, Macrophytes, Fish, Benthic animals Water quality: Total nutrients and pH Hazardous substances: EU’s Priority substances, National list of hazardous substances Hydro-morphological alterations: Magnitude of water level and discharge regulation of lakes and rivers, Modifications of river channels and lake shores, Migration barriers 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland2
3
Revision of classification and monitoring 2013 Classification revised for 2. water management cycle –New quality variables and indexes –Subtypes for Northern and Southern waters –Revised reference values and class limits for most variables Monitoring network revised by the end of 2013 –Pressures for cutting off the costs: reduction of monitored water-bodies and biological variables?? 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland3
4
Biological monitoring: Algae Lakes: Phytoplankton (NEW: littoral periphyton) Rivers: Periphyton (Diatoms) in rapids Coastal waters: Phytoplankton, Kelp vegetation (Southern areas) 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland4
5
Biological monitoring: Algae: Indicators (1) Phytoplankton: Reference values and class limits revised, new variables for lakes –Chlorophyll-α concentration –TPI (Trophic plankton-index) –Total biomass –Blue-green algae % of tot. biomass Macroalgae (Kelp) –Distribution and maximum depth of kelp vegetation –Kelp does not occur in Northern Baltic Sea 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland5
6
Biological monitoring: Algae: Indicators (2) Periphyton (Diatoms) –Formerly used IPS- index discarded –For rivers, Northern and Southern subtypes added –New reference values and class limits –Rivers & Lakes: Number of type-specific species (TT 40 ) Percent Model Affinity (PMA) 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland6
7
Biological monitoring: Macrophytes Lakes, use in rivers under development Northern and Southern subtypes Indicators: –Type-specific species % of tot. no. of species –PMA (Percent Model Affinity) –Eutrophication Index –NEW: Reference values for naturally eutrophic lakes 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland7
8
Biological monitoring: Benthic invertebrates Lakes: Profundal, (NEW: lake littoral area) Rivers: Rapids Coastal areas: Soft substrate bottoms 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland8
9
Biological monitoring: Benthos, indicators (1) Rivers and Lake littorals: new reference values and class limits for Northern and Southern freswaters Rivers: –No. of type-specific species (TT) –No. of type-specific sensitive (EPT) species –PMA (Percent Model Affinity) Lake littorals: –No. of type-specific species (TT) –PMA (Percent Model Affinity) 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland9
10
Biological monitoring: Benthos, indicators (2) Lake profundals: –BQI (Benthic Quality Index) discarded –Profundal Invertebrate Community Metric (PICM) –PMA (Percent Model Affinity), updated Coastal waters: –BBI (Brackish water benthic index), type-specific benthic index 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland10
11
Biological monitoring: Fish Lakes: Survey fishing with NORDIC-nets Rivers: Electrofishing of rapids –Updated reference values and class limits 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland11
12
Biological monitoring: Fish, indicators Lakes: Fish-index, includes: –Total biomass, Total no. of individuals –Cyprinid % of tot. biomass –Natural occurence of indicator species Rivers: FiFi-index, includes: –No. of species –Proportion of sensitive species –Proportion of tolerant species –Density of Cyprinid-populations –Density of natural Salmonid fry 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland12
13
Updates on water quality classifications River pH: classification based on mean of yearly minimum pH’s of observation period (recommended 2006-2012). Earlier, classification was based on observed minimum. Lakes: –New ref. values and class limits for P and N on shallow, humic lakes Coastal waters: –Based on tot. nutrient concentration in summer (previously based on winter observations). –Classifications for secchi depth and profundal oxygen concentration. 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland13

14 Characterized waters in Tana-Neiden-Pasvik Basin All rivers >100 km 2 and lakes >1 km 2 should be classified by June 2013. Data scarce -> expert judgement based on existing pressures using grouping of water bodies by type. 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland
15
2013: Classification of border rivers 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland15
16
Classification of border lakes 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland16
17
Example Lake Inari (Lagre clearwater lake -type) Biological elements: PhytoplanktonEQR = 1,48 Macrophytes /EQR = 0,56 PhytobenthosEQR = 0,83 Littoral benthos / EQR = 0,35 Profundal benthos EQR = 0,75 Fish EQR = 0,97 -> Biological status mean EQR = 0,84 -> Expert judgement 17 high moderate high poor good high good
18
Example Lake Inari (continued) Physico-chemical status –total nutrients etc. Chemical status –priority substances < EQS as expert judgement Hydromorphological status –slightly altered -> Ecological status high good
19
Moderate lakes in first period in RBD 6 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland19

21
Present monitoring in Lapland 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland21 -Biological sampling in majority of monitoring stations. -Monitoring sites represent existing surface water types (goal is to include at least 3 sites/type/Basin). -EU-directives cause pressures to increase the number of stations, especially on smaller rivers and lakes -Resources already insufficient…
22
Revision of national monitoring National monitoring network will be ”updated” by the end of 2013 Savings in state administration may create needs for reduction of monitoring costs –May cut down the number of monitoring stations and reduce monitoring frequency especially for biological variables Obligation monitoring by industry, mines etc. and voluntary monitoring by civil organisations should be fully utilized in monitoring –Limited possibilities in Northern Lapland due to lack of industry and small, aging population of the region –The quality of voluntary monitoring data? 17.4.2013Centre for Economic Development, Transport and the Environment in Lapland22
