The moles strike back

ThemolesstrikebackWe are using small, solar-powered ultra-sonic devices anchored into the ground to chase away the moles at our study site Neustift, which are a real pest in particular in spring time. As you can see in the picture, it looks like that this year the moles have decided to strike back, taking revenge on an ultra-sonic device by burying it in a molehill. Looks like we need to consider other options to get rid of them …

HiResAlp project started

On 18th March Georg attended the kick-off meeting of the HiResAlp project at Bozen/Bolzano. The project is coordinated by the Applied Remote Sensing group at EURAC and will investigate the water cycle of mountain ecosystems using a combination of remote sensing (in particular based on radar) and modelling.
