Today we had a very good meeting with the researchers from the project WetKit (www.wetkit.weebly.com). We will cooperate regarding sampling sites and sampling strategies and will thus get more data from the sites leading to better understanding on e.g. multi-functionality of CWs.

The nest box packages are designed to test effects of hole diameter and wood material on the nesting frequency of different species of solitary bees and wasps. The locations of the package were designed so we can get answers to questions on effects of distance from CWs, and effects of nearby surroundings. The map shows the locations of the 45 nest box packages and also the locations of 8 of the 85 trap nests, located in the stream Trönningeån drainage area.
We are networking with the project LIFE-Goodstream www.Goodstream.se and are using the large number of artificial nests that are planned to be deployed in the drainage area of the stream Trönningeån. In total 275 nest boxes are used. The nests boxes are bundled into 45 different “nest box packages”.
In June we have done surveys of flowering density and pollinators by transect walks in the 50 CWs.
Now all trap nests have been located at the CWs. In total 85 trap nests are deployed. In each trap nest there are 23 nesting tubes, giving at total of 1 955 available nests at the 85 CWs.
We have done the first sampling of pollinators using pan traps (colour bowls). 3 traps of different colour have been placed at 50 CWs.
We had a meeting with our project partners from Stockholm University to discuss the biodiversity sampling in our different projects.
We have started to place trap nests in constructed wetlands (CWs), and we use the same CWs we have selected for the project “Wetlands as Buffers” (see data on that project on the tab at the Homepage). The trap nests are placed on the wooden pole supporting the water level meters in the different CWs (see photo)
Welcome to BioWetland!
Wetlandscapes & Biodiversity – Buffer, Biodiversity and Bees
Research on how constructed wetlands(CWs) function hydrologically in a river basin perspective and how hydrology and its interactions with wetland design, location and management affect the biodiversity in wetlands and at the landscape level, with focus on arthropods in terrestrial-aquatic boundaries and pollinators.
