Monitoring, evaluatie en ecologisch advies

Ecoauthor is de onderneming van Dr. S. Wijnhoven (Sander). Naast dat Ecoauthor u allerlei diensten kan aanbieden met betrekking tot het omzetten van uw onderzoeksresultaten, monitoring gegevens en andere interessante ecologische bevindingen in een wetenschappelijke publicatie (zie Engelstalige pagina’s), heeft Sander o.a. ook grote kennis over de ecologie van de Nederlandse estuariene en mariene wateren en het monitoren van de biodiversiteit en het ecologisch functioneren in het bijzonder, waarvoor u hem ook kunt consulteren.

Sander’s expertise betreft o.a.:

  • Ontwerp en evaluatie van monitoring programma’s en veld experimenten
  • Organisatie en uitvoer van monitoring projecten en veld inventarisaties
  • Ontwikkeling van milieu- en ecologische kwaliteitsindicatoren
  • Uitvoer van systeem evaluaties en bekken rapportages
  • Impact studies en evaluatie van management en maatregelen
  • Ecologie van exoten
  • Literatuur studies en risico-analyses
  • Historische en lange termijn ontwikkelingen en referentie beelden

met veel ervaring in relatie tot de:

  • Wateren van de Zeeuwse en Zuid-Hollandse Delta (o.a. Westerschelde, Oosterschelde, Grevelingen, Veerse Meer, Haringvliet – Hollands Diep – Biesbosch)
  • Noordzee en Voordelta
  • Nederlandse Grote rivieren en hun uiterwaarden (Rijn / Waal, Maas)

in het bijzonder met betrekking tot het:

  • macrobenthos

maar daarnaast ook veel gewerkt aan o.a.:

  • andere macrofauna groepen
  • vissen
  • kleine zoogdieren
  • macro-algen

Sander heeft veel ervaring met:

  • Rapporteren & publiceren,
  • Grote / gecompliceerde datasets en data analyses
  • (Multi-variate) statistiek, statistische onderbouwing en toetsing
  • Gemeenschapsanalyses
  • Populatie ecologie
  • Niche identificatie

heeft daarnaast veelvuldig geparticipeerd in internationale netwerken,  presenteert frequent tijdens (internationale) congressen, symposia en workshops en is regelmatig betrokken bij onderwijs.

Publication providing elaborated guidance how to assess sea-floor integrity under the MSFD

doi:10.2760/8315684

Most EU countries have in the meanwhile reported on the marine benthic habitat quality status under the MSFD, taking into consideration the guidance on Article 8 assessment* in development and discussed in the Technical Group Seabed**. Although the assessment guidance with regards to sea-floor integrity will continue to be developed the coming years, now an interim overview has been published. It provides the current status of guidance with more elaborated information, examples and ways of handling data, use of indicators and the first agreed threshold values.

RAICEVICH, S., KORPINEN, S., SCHROEDER, A., WIJNHOVEN, S., DINESEN, G.E. et al., Assessment of sea-floor integrity under the EU Marine Strategy Framework Directive – Supplementary information to the Article 8 assessment guidance, ALONSO ALLER, E. and VIGHI, M. (editors), Publications Office of the European Union, Luxembourg, 2025, https://data.europa.eu/doi/10.2760/8315684, JRC142314.

The report provides supplementary information to the Article 8 assessment guidance document (European Commission, 2022) where:

  • the physical pressures impacting the sea-floor and benthic habitats are defined,
  • human activities causing such pressures are discussed,
  • elements to be assessed are identified,
  • assessment scales and marine reporting units are proposed,
  • inter-relations with other MSFD criteria and other policies are identified and integration with them suggested,
  • the agreed threshold values are presented, and
  • approaches to address uncertainty are discussed.

TG Seabed has agreed on the general principles of the assessment of sea-floor and benthic habitats, such as pressure definitions, definition of adverse effects and necessary thresholds indicating good status. With these general principles, the coherence of the Member States assessments under Descriptor 6 will improve, and it is anticipated that many details will likely become clearer once good practices have accumulated from the upcoming assessments.

This report has been updated to integrate the latest developments under TG Seabed until December 2023, and thus includes references to the D6C4 and D6C5 threshold values proposed by TG Seabed and adopted by MSCG on 15 March 2023 and endorsed by Marine Directors on 4 June 2023.

* The assessment of the sea-floor and benthic habitats of Europe’s seas is a requirement of the EU Marine Strategy Framework Directive (MSFD) under the qualitative descriptor 6 (“Sea-floor integrity is at a level that ensures that the structure and functions of the ecosystems are safeguarded and benthic ecosystems, in particular, are not adversely affected”). Article 8 of the MSFD requires this assessment, while Commission Decision 848/2017 lays down the criteria and methodological standards for such an assessment. The guidance document #19 for the MSFD implementation provides an overview of the assessments under Article 8 for all the qualitative descriptors, while this report aims to give a more elaborated guidance for Descriptor 6.

**TG Seabed is the ‘technical group on seabed habitats and sea-floor integrity’ established by the Member States and the European Commission under the MSFD Common Implementation Strategy.
