“…This implies that only glide rates with a high (2) or very high (1) intensity can be considered as critical for juvenescent trees. The necessary force to uproot young trees (stem diameter 0.025 m, height 0.5 m) is about 1,000 N (Höller et al 2009); according to Höller et al (2009), values of this magnitude can be regularly caused by gliding on a smooth ground surface (where glide rates correspond to a high (2) and very high (1) intensity). To ensure tree growth under these conditions, it may not be sufficient to plant a high number of tress.…”

“…To ensure tree growth under these conditions, it may not be sufficient to plant a high number of tress. Although 3,000 to 5,000 plants/ha were afforested in the surroundings of the experimental site (unpublished map of the Austrian Service for Torrent and Avalanche Control), many trees were damaged by intensive gliding (Höller et al 2009). In order to reduce gliding (and to avoid snow glide damages), appropriate measures (see below) must be considered.…”

“…Surface roughness is relevant for glide avalanches on micro-level as well as for snow slabs on meso-and macro-level. The estimated skid factors are introduced in snow gliding and snow pressure modeling [9].…”

“…The slope angle, the micro relief, and the hydrological properties of the slope influence the glide velocity (Ceaglio et al, 2017;McClung and Schaerer, 1999;Margreth, 2007). Friction originated by the vegetation depends on its composition and height (Höller et al, 2009). Both the vegetation and the micro relief depend on the land use, which is an input for snow glide modeling (Leitinger et al, 2008;Maggioni et al, 2016).…”
