More than 1300 tree species live in cities: are they gateways for forest pests?

There are more than 1300 tree species in Swiss cities, while our forests are home to only 76, according to a study by the WSL. This means that introduced forest pests or diseases also find significantly more potential hosts in cities – and could spread from there into the forests.

Lasers for more road safety

This winter, the SLF tested a new system to better assess the risk of avalanches to traffic routes. The results are promising and should allow roads and railroad lines to be closed for shorter periods of time in the future when conditions are tight.

European forest monitoring proposal criticised

The European Commission is planning to monitor forests more closely, combining data from the ground and from the air. However, its proposal ignores important existing resources, criticise forest researchers from all over Europe in an opinion piece in "Forest Ecology and Management".

First spin-off at the SLF

The RAMMS software for modeling avalanches, debris flows and rockfalls is being incorporated into a specially founded AG.

Machine learning helps researchers to use weather stations to investigate the consequences of climate change for the growth of alpine vegetation.

Shoveling loads of snow

SLF researchers investigate in deep holes whether satellite data accurately show snowmelt to improve hydrological discharge forecasts.
