Abstract Understanding the spatial patterns of fire occurrence and its response to climate change is vital risk mitigation vegetation management. Focusing on boreal forests in Northeast C hina, we used point pattern analysis model reported from 1965 2009. Our objectives were quantitate relative importance biotic, abiotic, human influences map distribution density (number fires occurring over a given area time period) under current future conditions. results showed human‐caused strongly...
Increasing evidence indicates that forest disturbances are changing in response to global change, yet local variability disturbance remains high. We quantified this considerable and analyzed whether recent episodes around the globe were consistently driven by climate, if human influence modulates patterns of disturbance. combined remote sensing data on (2001-2014) with in-depth information for 50 protected landscapes their surroundings across temperate biome. Disturbance highly variable,...
Understanding disturbance and recovery of forest landscapes is a challenge because complex interactions over range temporal spatial scales. Landscape simulation models offer an approach to studying such systems at broad Fire can be simulated spatially using mechanistic or stochastic approaches. We describe the fire module in explicit, model landscape dynamics (LANDIS) that incorporates fire, windthrow, harvest with species-level succession. A suited are designed simulate patterns large time...
The LANDIS model simulates ecological dynamics, including forest succession, disturbance, seed dispersal and establishment, fire wind their interactions. We describe the addition to of capabilities simulate vegetation management, harvest. Stands (groups cells) are prioritized for harvest using one four ranking algorithms that use criteria related management objectives. Cells within a selected stand harvested according species age cohort removal rules specified in prescription. These flexible...
Abstract: The lack of management experience at the landscape scale and limited feasibility experiments this have increased use scenario modeling to analyze effects different actions on focal species. However, current approaches are poorly suited for analysis viability in dynamic landscapes. Demographic (e.g., metapopulation) models species living these landscapes do not incorporate variability spatial patterns early successional habitats, been linked population models. We link a model...
Abstract The spatial pattern of forest fire locations is important in the study dynamics disturbance. In this article we used a point process modeling approach to quantitatively effects land cover, topography, roads, municipalities, ownership, and population density on occurrence reported between 1970 2002 Missouri Ozark Highland forests, where more than 90% fires are human-caused. We AIC (Akaike information criterion) method select an appropriate inhomogeneous Poisson model best fit data....
Abstract Extreme precipitation often persists for multiple days with variable duration but has usually been examined at fixed duration. Here we show that considering extreme persistent by complete event duration, rather than a temporal period, is necessary metric to account the complexity of changing precipitation. Observed global mean annual‐maximum significantly stronger (49.5%) extremes daily extremes. However, both globally observed and modeled rates relative increases are lower compared...
Abstract Treeline responses to environmental changes describe an important phenomenon in global change research. Often conflicting results and generally too short observations are, however, still challenging our understanding of climate‐induced treeline dynamics. Here, we use a state‐of‐the‐art dendroecological approach reconstruct long‐term the position alpine relation air temperature at two sides Changbai Mountains northeast China. Over past 160 years, increased by around 80 m, process...
Abstract Human activities have altered disturbance patterns in many parts of world, but there is no quantitative information on and trends forest regimes China. We applied a spectral-temporal segmentation approach over all available Landsat data to map individual patches characterize the rate, size, frequency, severity across China’s forests. From 1986 2020, about 39.7% forests were disturbed with an annual rate 1.16 ± 0.41% yr −1 . The decreased at −390 142 km 2 , primarily driven by...
Natural disturbance patterns can provide useful information for ecosystem management. Our objective was to a detailed spatial picture of the pre-European settlement vegetation cover northwestern Wisconsin Pine Barrens and compare it with present cover. We analyzed presettlement conditions using an extensive data set comprised U.S. General Land Office surveyor records from mid-19th century related in 1987 as depicted Landsat satellite forest classification. Changes were quantified by...
