The pine stand in the Havraní Skála locality in the Bohemian Switzerland National Park was affected by an extensive mixed-severity wildfire in summer 2006. The fire severity, fire type and fire extent were assessed by various fire severity measures collected in the field (mean bole char height on stems on sample plots, content of oxidizable C and total N at a soil depth of 0–5 cm), as well as by classification and filtering of green canopy cover from time series of aerial photographs acquired before the fire (2005), soon after the fire (2006) and one year after the fire (2007). The specific image analyses made it possible to uncover the spatial and temporal pattern of the stand defoliation. The central part of the site was mainly affected by the crown fire and thus defoliated substantially right during the fire. On the contrary, the peripheral part of the site was mostly affected by low-severity ground fire and therefore defoliated progressively one year later. All the fire severity measures used were well related.

Research in the Sierra Nevada range of California, USA, has provided conflicting results about current trends of high-severity fire. Previous studies have used only a portion of available fire severity data, or considered only a portion of the Sierra Nevada. Our goal was to investigate whether a trend in fire severity is occurring in Sierra Nevada conifer forests currently, using satellite imagery. We analysed all available fire severity data, 1984–2010, over the whole ecoregion and found no trend in proportion, area or patch size of high-severity fire. The rate of high-severity fire has been lower since 1984 than the estimated historical rate. Responses of fire behaviour to climate change and fire suppression may be more complex than assumed. A better understanding of spatiotemporal patterns in fire regimes is needed to predict future fire regimes and their biological effects. Mechanisms underlying the lack of an expected climate- and time since fire-related trend in high-severity fire need to be identified to help calibrate projections of future fire. The effects of climate change on high-severity fire extent may remain small compared with fire suppression. Management could shift from a focus on reducing extent or severity of fire in wildlands to protecting human communities from fire.

Ten years of vegetation dynamics in a forest fire patch in Leuk (Valais) The stand-replacing forest fire of Leuk (2003) extends from 900 to 2100 m a.s.l. and covers an area of 300 ha, which represents a big disturbance event in Switzerland, although it is small in a global perspective. Its location along a wide elevational gradient has offered a unique opportunity to study the dynamics of plant species richness and natural tree regeneration in relation to different environmental drivers. The vegetation was assessed on a systematic grid including 148 relevé plots and 5 time steps. Results show a peak of species richness in the fourth year after the disturbance and a distinctly higher number of species compared to the pre-fire forests. The increase of species richness during the first four years was slower on plots with highest fire severity. Above 1600 m a.s.l. species richness rose quickly above average due to the appearance of various mountain species. Tree regeneration has advanced in all studied elevation belts. Ten years after the disturbance, sapling densities ≥25 cm reached a rather low level of 1800 to 3000 stems per hectare. Aspen (Populus tremula), willow (Salix appendiculata and S. caprea), as well as birch (Betula pendula) are most abundant up to 1700 m a.s.l., where up to 95% of the regeneration consists of broadleaves. Above, European larch (Larix decidua) and Norway spruce (Picea abies) each constitute 12% of the regenerating saplings. At lowest elevations, oaks (Quercus pubescens) have established more frequently (6.4%) after ten years than Scots pine (Pinus sylvestris; 3.7%), even though the proportion of these formerly stand-forming tree species is still quite modest compared to the total number of stems per ha. Looking ahead, a young forest will grow on the forest fire patch, developing towards a larch-spruce forest at high elevations and towards a mixed forest with a considerable proportion of oak at low elevations. It may take quite a while until prevailing aspen, willow and birch will be overgrown by conifers and oaks.
