Myosotella denticulata not that rare in the Western Scheldt

At the moment Ecoauthor is monitoring the presence of non-indigenous species in the intertidal zone along the Western Scheldt (‘Westerschelde’). Besides valuable information on the distribution of exotic species (results will follow later this year), the monitoring also gives insights in populations of indigenous species. For the second year in row Myosotella denticulata (‘Meertandig muizenoortje’ in Dutch) is found to be common in the high intertidal parts near Bath. Myosotella denticulata is specifically found in the spaces between the blocks that pave the dikes. The ecological atlas (De Bruyne et al., 2013) records the species for just one 10×10 km gridcell in the entire South-western Dutch delta, although it is already mentioned that the species might be more common than suggested. We did also observe the species near Breskens and Hansweert in a similar habitat before (Wijnhoven et al., 2015).

Research is part of the Transect Monitoring project commissioned by the Netherlands Food and Consumer Product Safety Authority (NVWA).

Ecoauthor participated in trinational workshop Doggerbank

Last February the 8th, a trinational workshop on joint monitoring, evaluation and knowledge exchange concerning the Doggerbank was held in Hamburg. With several participants from Germany and the UK, Ecoauthor represented the Dutch government. Although monitoring programmes in the three countries are quite different, it is clear that cooperation will have benefits for each of the countries. As a first step, benthic monitoring data will be exchanged, and the various indicators in use will be applied on each others datasets. The tuning of evaluations should lead to a joint evaluation of the international Doggerbank region in the near future. Also joint monitoring activities are foreseen. doggerbank-monitoring-nl-v060217

Ecoauthor has signed Framework Agreement with Rijkswaterstaat

Western Scheldt 2016Ecoauthor is happy that the Framework Agreement Biology concerning Specialist Advice and Methodology Development was awarded to us by Rijkswaterstaat (RWS-CIV, Dutch Ministry of Infrastructure and the Environment) for a range of competences in the field of Hydrobiology, Ecological Monitoring of Flora & Fauna, and Ecological Mapping. The Agreement is signed for three years. We are looking forward to a fruitful cooperation and are ready to put it in practice.
