Miller (1966: 1) observed "Forest covers much of that portion of the earth that receives some of its precipitation in the form of snowfall. Yet many questions about the amount of snowfall that penetrates forests to reach the soil surface remain unanswered." Nearly two decades later Miller's statement remains true. The effects of forest on snow cover are variable. Seppanen (1961) reported that in some places in Finland, more snow accumulated in forest than in open locations, and in other places less; the relationship differed between years. Harestad (1979) documented the same pnenomenon on Vancouver Island.
