The estimates of the all-years and all-regimes models were so similar that the results of both combined are shown here (see text for details). Normal: unmanipulated snow depth as found representative for most of the study area; Deep: manipulated snow depth with snow fences; Shallow: unmanipulated snow regime shallower than Normal as found on slightly elevated ridges throughout the study area; Medium: increased manipulated snow regime shallower than Deep.
