. 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 ...
Although severely burned areas may function very differently than the pre-fire environment, these areas may provide unique habitat or structural components (i.e., high snag density, low tree canopy cover, high woody debris on the forest floor, many early successional plant species, etc.) that ...
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...
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 ...
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....
