“…Annual variation in weather conditions will affect these controlling factors, but the weather also directly influences the physiology and propagation rate of herbivorous insects [ 76 ]. Increases in mean temperature because of climate warming affect the warming-induced distribution shift of forest insects towards high latitudes [ 24 , 26 ] and high altitudes [ 76 ]. Thus, in the future, a higher risk of insect outbreaks in boreal and subarctic forests will come from more frequent outbreaks of native species and additional outbreaks by invasive exotic forest insects.…”

“…I. typographus attacks are predicted to increase on P. abies [ 26 ], with increased effective temperature sums coinciding with more favorable conditions for swarming. Areas with favorable temperature sums for the complete development of bivoltine populations of I. typographus (>1500 degree days (DD)) shifted northwards by an average of 450 km during the entire study period of 1960–2016 [ 26 ]. Massive 2.5 M ha outbreaks of the Siberian silk moth Dendrolimus sibiricus have shifted northward by up to 500 km in the Siberian boreal conifer forest during the last 40 years with the shift promoted by droughts and an increase in the temperature sum [ 81 , 82 ].…”

“…Insects are the major poikilothermic animal group to take advantage of a warming climate. There is already evidence that rapidly reproducing and invasive insect herbivores have become more common at northern latitudes and attack forest trees at higher rates causing serious outbreaks and forest decline in boreal conifer forests [ 24 , 25 , 26 ] and in subarctic deciduous forest [ 27 , 28 ].…”

Compared to most other forest ecosystems, circumpolar boreal and subarctic forests have few tree species, and are prone to mass outbreaks of herbivorous insects. A short growing season with long days allows rapid plant growth, which will be stimulated by predicted warming of polar areas. Emissions of biogenic volatile organic compounds (BVOC) from soil and vegetation could be substantial on sunny and warm days and biotic stress may accelerate emission rates. In the atmosphere, BVOCs are involved in various gas-phase chemical reactions within and above forest canopies. Importantly, the oxidation of BVOCs leads to secondary organic aerosol (SOA) formation. SOA particles scatter and absorb solar radiation and grow to form cloud condensation nuclei (CCN) and participate in cloud formation. Through BVOC and moisture release and SOA formation and condensation processes, vegetation has the capacity to affect the abiotic environment at the ecosystem scale. Recent BVOC literature indicates that both temperature and herbivory have a major impact on BVOC emissions released by woody species. Boreal conifer forest is the largest terrestrial biome and could be one of the largest sources of biogenic mono- and sesquiterpene emissions due to the capacity of conifer trees to store terpene-rich resins in resin canals above and belowground. Elevated temperature promotes increased diffusion of BVOCs from resin stores. Moreover, insect damage can break resin canals in needles, bark, and xylem and cause distinctive bursts of BVOCs during outbreaks. In the subarctic, mountain birch forests have cyclic outbreaks of Geometrid moths. During outbreaks, trees are often completely defoliated leading to an absence of BVOC-emitting foliage. However, in the years following an outbreak there is extended shoot growth, a greater number of leaves, and greater density of glandular trichomes that store BVOCs. This can lead to a delayed chemical defense response resulting in the highest BVOC emission rates from subarctic forest in the 1–3 years after an insect outbreak. Climate change is expected to increase insect outbreaks at high latitudes due to warmer seasons and arrivals of invasive herbivore species. Increased BVOC emission will affect tropospheric ozone (O3) formation and O3 induced oxidation of BVOCs. Herbivore-induced BVOC emissions from deciduous and coniferous trees are also likely to increase the formation rate of SOA and further growth of the particles in the atmosphere. Field experiments measuring the BVOC emission rates, SOA formation rate and particle concentrations within and above the herbivore attacked forest stands are still urgently needed.

Under the moderate future greenhouse gas emissions scenario (RCP4.5), climate model simulations project that the annual mean temperature will increase in Europe by up to 2–3 °C by the middle of this century, compared to the end of the nineteenth century. The temperature increase is projected to be larger in Northern Europe than in Central and Southern Europe. The annual precipitation is projected to decrease in Southern Europe and increase in Northern and Central Europe. The projected changes in temperature and precipitation are expected to be higher in the winter than in the summer months. In Northern Europe, forest growth is generally projected to increase due to warmer and longer growing seasons. In southern Europe in particular, warmer and dryer summers are projected to decrease forest growth. Climate change is expected also to expose forests and forestry to multiple abiotic and biotic risks throughout Europe. The greatest abiotic risks to forests are caused by windstorms, drought, forest fires and extreme snow loading on trees. The warmer climate will also increase biotic risks to forests, such as damage caused by European spruce bark beetle (Ips typographus) outbreaks in Norway spruce (Picea abies) forests and wood decay by Heterobasidion spp. root rot in Norway spruce and Scots pine (Pinus sylvestris) forests. Different adaptation and risk management actions may be needed, depending on geographical region and time span, in order to maintain forest resilience, which is also important for climate change mitigation.

Natural disturbances drive forest dynamics and biodiversity at different spatial and temporal scales. Forests in the boreal biome are shaped by several types of disturbance, including fire, windthrow, and insect outbreaks, that vary in frequency, extent, severity, and specificity. In managed forests, disturbances also affect the amount and quality of available timber. Ecosystem management uses information on disturbance regimes as a guide to finding a balance between ecological, economic, and social viewpoints. In this chapter, we review current knowledge on disturbance regimes in boreal forests and discuss some implications for managing the impact and risk of disturbances in the context of forest ecosystem management and restoration.
