Johanna Ugander has now defended her thesis on the importance of submerged vegetation presence and species composition for the biodiversity and abundance of invertebrates. The studies were done in LIFE-Goodstream measures, and her work gave valuable data for the evaluation of our measures in the project. The thesis-report can be found under the tab Publications
Our work with schhols continue, and this week three different 8 grade classes from the school ”Kärlekens skola” have been visiting our sites during three half-days. We informed about the project and as part of their education they helped us monitor the numbers of invertebrates in the wetlands.
Further surveys by the County adminsitration and Halmstad municipality have revealed very high concentrations of PFAS. Analyses show 20 000 ng/l! The limit set by the SEPA is 90 ng/l!
During the summer we have published several reports with information on the project. It includes a report showing all measures that have been constucted in the project and reports on the effects on biodiversity of the measures The project has also been in various media, e.g. ”Radio P4 Halland” and different magazines. You can find the reports and media appearances under Dessimination/Publication. The photo shows a collection of ”dragonfly faces” from the surveys in the project.
Sara Bishoff from The Brandenburg University of Technology, Germany, did her bachelor thesis here in Halmstad in LIFE-Goodstream. She studied factors determining the abundance of dragonflies in LIFE-Goodstream measures.
Among other things she found that vegetations is a crucial factor for dragonfly abundance and that our small amphibian ponds are good habitats also for dragonflies. Her sampling of dragonfly larvae also generated a new project species; white-legged damselfly (Platycnemis pennipes), see photo of that species above. The thesis can be found under Publications.
The monitoring during 2019 and first half of 2020 indicates that our measures have been positive for the biodiversity. The species list increases continously, for the project in total and at the different constructed wetlands. The photo shows Brilliant emerald (Somatochlora metallica) a new species for LIFE-Goodstream during 2020. So far 30 species of dragonflies have been observed in LIFE-Goodstream measures which corresponds to 46 % of all dragonfly species observed in Sweden and 71 % of the species observed in the municipality of Halmstad.
During 2020, so far four new publications have been uploaded on the homepage. They consist of two abstract for international conferences in The Netherlands and Australia (cancelled or postponed due to Corona), one manual for construcion of our bee-boxes and one interim report on the biodiversity monitoring in LIFE-Goodstream.
They can all be found under the link: Dissemination/Publications
The 28 of April the Swedish EPA arranged a start-up meeting (via Skype due to Corona) for the 8 projects selected for the Wetland Ecosystem services call. We were granted one of the projects and will investigate how constructed wetlands in the agricultural landscapes function for water buffering and water storage. LIFE-Goodstream wetlands are an important part of the project.
LIFE14 ENV/SE/000047 is being implemented with the contribution of the LIFE financial instrument of the European Union
The project is co-financed by The Swedish Agency for Marine and Water Management by grant 1:12; Measures for marine and water environment.
