REFRESH stakeholder meeting in Estonia

Estonia Stakeholder PresentationOn 8th May 50 people attended a REFRESH stakeholder meeting in at the Estonia Science Centre, Tartu, Estonia. The purpose of the meeting was to advise the stakeholders, mainly Estonian Water Authorities, how best to consider climate change impacts in preparing revised River Basin Management Plans (RBMPs) for 2015-2021, in particular how to integrate climate change into the second round of river basin planning and lake restoration.

The first presentation was given by a Jaak Jaagus, a climate researcher who explained the basic terms and approaches and the general projections for Estonia.  Arvo Järvet, a hydrologist explained how climate is expected to affect the different steps of the water cycle. Peeter Nõges, a REFRESH scientist presented a report prepared last year for the Estonian ministry on climate change impacts on aquatic ecosystems in Estonia and implications for the monitoring system. Peeter also presented results from REFRESH of relevance to the climate change impacts in revised RBMPs. Two talks about lake restoration were given by Lea Tuvikene and Ingmar Ott. 


Beysehir OutflowThe fourth REFRESH project meeting was held in Antalya (Turkey) from 22nd to 26th March, 2012. The meeting was jointly hosted by our colleagues from the Middle East technical University (METU). The agenda comprised a mixture of plenary sessions (introductory and reporting back), work package workshops and integrated workshops cutting across two or more work packages.

WISER Special Issue; Hydrobiologia, March 2013

WiserlogoA new special issue in the journal "Hydrobiologia" appeared in March 2013, entitled "Water Bodies in Europe - integrative systems to assess ecological status and recovery". It summarises the results of the EU-funded project WISER ( The special issue includes 31 peer-reviewed papers, addressing the assessment and restoration of lakes, coastal and transitional waters, and rivers in Europe. For lakes and coastal/transitional waters individual papers address new assessment systems using phytoplankton, macrophytes, benthic invertebrates and fish. For all ecosystem types the effects of restoration measures are addressed. The results are based on the analysis of a huge data source, covering different organism groups and ecosystem types in almost all European ecoregions. A special focus is on uncertainty in bioassessment methods. Link to the Special Issue:

Beavers: natural water engineers at REFRESH research location

GrooteMolenbeek BeaversThe beaver population is steadily increasing in the province of Limburg, the Netherlands. Since the introduction of 33 beavers in 2002, the population has increased to approximately 200 individuals. Recently, signs of beaver activity have been encountered at the REFRESH research location at the Groote Molenbeek. During last summer’s field work for REFRESH, the Dutch team found several logged Salix trees (picture left). Surprisingly, these trees were located in the proximity of the dam construction of the flooding experiment. During the following months no beaver dams were encountered close to the experimental section. 

On January 3rd 2013 the Dutch National news program NOS showed a news item concerning the increasing beaver population in Northern Limburg. The beaver dams discussed here are located approximately five kilometers downstream of our research sections. At this location, the Groote Molenbeek flows next to a major road (A73). The beaver dams even form a threat to the stability of this road. Currently, managing this natural water engineer’s population is daily business in Northern Limburg. Dutch governmental costs for managing the beaver population: 400 tons per year.
