Monitoring & ‘Local’ expertise

You can also contact Sander Wijnhoven for his specific expertise related to the ecological functioning and (long-term) developments of the Dutch coastal waters and the Dutch delta waters in particular, and his expertise related to exotic / non-indigenous species in estuarine and marine systems. Executive research tasks like inventories, monitoring and field-experiments (especially in the above identified region) as well as desk studies and advice based on own data and/or with consultation of his network will also be considered.

In relation to field work, please take into account that Ecoauthor holds office in the Netherlands and that it will be critically evaluated whether we can offer the expertise and arrange the logistics for you. For more details see Sander’s expertise site in Dutch or contact me via the contact form.

Quality status benthic habitats Dutch North Sea

The Ecoauthor report on the quality status and developments of benthic habitats and MSFD-areas of the Dutch North Sea is now available. The report presents the results of the application of the Benthic Indicator Species Index (BISI) on the 2015 monitoring data (considered the T0 as various measures of the Dutch Action plan Marine Strategy were just or still had to be implemented in 2015) and compares the quality status with the recent historic developments.

Some of the most important findings are:

– A stagnation and recent decline in the benthic habitat quality of offshore areas like the Frisian Front and Central Oystergrounds after years of improvement. This might be the result of a gradual movement of (seafloor disturbing) fisheries from the coastal zone to the offshore regions as suggested by results of specific BISI analyses (focussed on specific indicator species for seafloor disturbance) and the possible first improvements as observed in coastal areas.
– The permanent large impact of amongst others nutrients and pollutants (summarized as ecological disturbance) on benthic habitat quality, especially in the coastal zone, but also extending to further offshore areas like the Doggersbank. Although ecological disturbance is the most important pressure in the area of the Doggersbank, the observed decrease in benthic quality during the last two decades seems to be the result of increasing seafloor disturbance.

The study was commissioned by the Dutch Ministry of Agriculture, Nature and Food Quality (LNV) in consultation with the Ministry of Infrastructure and Water Management (IenW), and executed in cooperation with Wageningen Marine Research (WMR).
