Hi Sinja -
You probably have figured it out from the comments in this thread, but March is still Winter at high altitudes...lots of snow. In addition to blocking trails....except for the ones that are groomed for winter hiking as noted by Arno....there is significant potential for snow slides.
Even at lower altitudes in non-Alpine Switzerland, Spring has not really begun.
That may not mean snow on the ground, but the trails may not be cleaned up by the responsible local government until April or May...or June.
