Several different silvicultural treatments were studied in two experiments. In the first, mechanical scarification, slash removal, vegetation control, clear-cut age and seedling types were investigated with respect to frost injury to Norway spruce (Picea abies (L.) Karst.) seedlings. Frost damage was also related to near-ground minimum temperature. In the other experiment, the effects of Scots pine (Pinus sylvestris (L.)) shelterwood density gradients, ranging from dense, uncut forest to complete clear-cuttings, were analysed. Near-ground temperature and radiation were monitored close to planted Norway spruce cuttings with a mobile data acquisition system. Growth, frost damage and chlorophyll fluorescence were monitored and analysed in rela...
