forest conversionregeneration failurewildfiresWildfire-mediated changes to forests have prompted numerous studies on post-fire forest recovery of coniferous forests. Given climate change, a growing body of work demonstrates that conifer regeneration in temperate and boreal forests is declining, a phenomenon ...
. Among them, disturbance severity has been shown to strongly influence seedling recruitment (Turner et al.1999,2003; Jayen et al.2006; Maia et al.2012; Hollingsworth et al.2013). In particular, fire can produce different impacts on the below- and above-ground components of forest ecosystems...
However, for other wildland regions that are less affected by human activity, anthropogenic climate change still exerts predominant impacts on fire by increasing lightning ignitions in boreal forest12 and permafrost13 regions, and modulating either fuel availability in resource-limited fire regimes (e....
摘要: One approach to ecosystem management is to emulate the effects of natural disturbance in producing landscape patterns; this approach requires a spatial analysis of the pattern and ... 查看全部>>关键词: Boreal forest Ecosystem management Equilibrium Fire frequency Fire history Forest fires Forest...
What causes are attributed to low tree regeneration densities post fire? 3) What are the ecological and management implications for the future throughout the West, particularly where extensive mature tree mortality due to fire is coupled with low regeneration densities?
fire could destabilize forest carbon and biodiversity, thus protection priority areas were identified when both including (left columns) and excluding (right columns) forestland with high future vulnerability as simulated with CLM4.5. These forest priority areas were identified by sequentially combining ...
Forest decline Tree canopy loss associated with a complex interaction of biotic and abiotic factors leading to decreasing tree vigor and mortality; forest decline is not associated with fire, wind, harvest, or land use changes. Forest health A subjective concept incorporating themes such as biodiversi...
In arid and semi-arid forest ecosystems, soil fertility is often reduced due to the low vegetation cover, overgrazing fire and erosion (Faramarzi et al. 2018; Bracken et al. 2019; Moradizadeh et al. 2020; Yıldız et al. 2022). Thus, in these regions, where temporal and spatial ...
The primary aim of this study was to decipher the effect of fire disturbances on the changes in the forest composition during the past ca. 10,700 years. We also paid attention to the effect of impact of human, herbivore, pathogens, and climatic disturbance factors on the forest development....
Prevalence of “fire weather”—a function of temperature, precipitation, humidity, and wind speed—may be ENSO-modulated (Mason et al., 2017; Shen et al., 2019), but aside from fuel-limited drylands, and accounting for variable forest-management practices, burned area is expected to ...
