Ratio has been calculated in two test zones based on multibeam. |
Keeled Tubeworm (Pomatoceros triqueter) clusters were present in 60% of the samples. It has proved practically impossible to look at the relative number of disturbed clusters, but a statement can be made about the presence of intact clusters. Small, medium and large clusters of P. triqueter were observed on 166 stones of the total of 1417 sampled stones (i.e. on 11.70% of stones), but their distribution was rather patchy and limited in space.
|
The percentage of damaged Asterias rubens (Common starfish) was rather low. However, recent observations in wind farms have shown that this indicator does not provide reliable results. Any form of soil disturbance is excluded in the wind farms, but disturbed A. rubens are nevertheless observed. These results are therefore not taken into account when assessing the condition of the gravel beds.
|
No specimen of Alcyonidium spp. Found
|
No adult specimen of Alcyonium digitatum found, only small (<1 cm) observed |
Only 1 small (<5 cm) and young specimen observed. |
No specimens of Haliclona oculata found.
|
Most specimens of Mytilus edulis observed are small (<1 cm), 8 are medium (1-5 cm), and none are large (> 5cm). The medium specimens are over 1 year old and can be considered as adults (reproducing) (% of samples).. |
No specimens of Ostrea edulis found.
|
40% or 7 full grown (>5 cm) reefs of Buccinum undatum in 4 samples observed (% of samples). |
Some small reefs of Sabellaria spinulosa observed, only 1 full grown (% of samples). |
No species detected

Physical disturbance has been calculated per activity. Fishery affects approximately the whole area based on the current grid data (OSPAR). Other human activities account for a disturbed area of 2.5 à 3% per year with as two most important activities sand extraction ranging from 1.93 to 2.69% and dredging& dumping from 0.29 to 0.73. (link doc lars) fishery: ospar indicator) |
Physical loss has been calculated per activity, for windmills and energy cables the surface doubled with an insignificant increase of 0.12 km2 during the period 2012 till 2016. |

Description criteria |
Significant methodological progress was made in the acoustic mapping of seabed habitats (sludge, sand and coarse-grained sediment). Changes were observed with respect to sediment mapping in the initial assessment, but are mainly due to a difference in methodological approach. A multi-criteria approach is needed to be able to interpret seabed changes due to human activities.

A method was developed to quantify silting up in gravel areas. Time series of acoustic measurements of the seabed mainly showed fluctuations within the error margin. More detailed seabed classifications made it possible to indicate variations in the gravel / sand ratio that could be related to changing sedimentation.

Description overall status |
Due to the relatively poor score of the Belgian habitats due to fishing pressure (by means of the Margalef diversity index) in the OSPAR context, and to a very limited extent by the dumping of dredged material and aggregate extraction (by means of BEQI EQR scores with threshold 0.6), the soft substrate becomes as assessed unfavorably. With regard to changes in the occurrence of species in these specific macrobentic habitats, the period under investigation is too short to draw any conclusions. Many important benthic species are observed only very sporadically, due to their rarity or to the non-optimal sampling technique. The condition of gravel beds (hard substrates) is assessed as highly disturbed. Many of the target species included in the different environmental goals are missing or have only been observed as juveniles or in depleted condition.

Due to the relatively poor score of the Belgian habitats due to fishing pressure (by means of the Margalef diversity index) in the OSPAR context, and to a very limited extent by the dumping of dredged material and aggregate extraction (by means of BEQI EQR scores with threshold 0.6), the soft substrate becomes as assessed unfavorably. With regard to changes in the occurrence of species in these specific macrobentic habitats, the period under investigation is too short to draw any conclusions. Many important benthic species are observed only very sporadically, due to their rarity or to the non-optimal sampling technique. The condition of gravel beds (hard substrates) is assessed as highly disturbed. Many of the target species included in the different environmental goals are missing or have only been observed as juveniles or in depleted condition.

Physical disruption is more difficult to estimate and is currently limited to the effective locations of human activities, plus a theoretical buffer. Fishing is omnipresent. OSPAR data for the period 2011-2015 showed important spatial differences in fishing intensity for the entire FDNZ, albeit with the greatest intensities in the near-coastal zone where infralittoral and circalittoral sludge deposits and sand dominate. In these areas, dredging and unloading of dredged material contribute to the physical disruption. Marine aggregate extraction mainly disrupts sea-facing sands and coarse-grained sediments. There are no major increases or decreases over the 2011-2016 period.

The spatial range of physical loss in the Belgian part of the North Sea is limited. The largest loss of the original habitat type is mainly related to protective rock deposits over the gas pipelines (8.08 km2). The share of wind turbines, energy and telecommunication cables (0.05 km2), wrecks (0.17 km2), measuring poles and radar stations (0.002 km2) in the BPNS is limited in the use of space. Only an increase in physical loss can be seen by the installation of wind turbines, from 0.04 km2 in 2011 to 0.09 km2 in 2016, and the installation of associated energy cables, from 0.04 km2 in 2011 to 0.08 km2 in 2016. Given the port infrastructure located inland from the 2012 baseline, it does not affect the figures.
