Mapping Mountain Pine Beetle Mortality through Growth Trend Analysis of Time-Series Landsat Data
Disturbances are key processes in the carbon cycle of forests and other ecosystems. In recent decades, mountain pine beetle (MPB; Dendroctonus ponderosae) outbreaks have become more frequent and extensive in western North America. Remote sensing has the ability to fill the data gaps of long-term infestation monitoring, but the elimination of observational noise and attributing changes quantitat...
متن کاملMapping Percent Tree Mortality Due to Mountain Pine Beetle Damage
The mountain pine beetle (Dendroctonus ponderosae Hopkins) is a pervasive and particularly destructive species of insect that has killed vast areas of conifers in western North America. To map large areas of infestation satellite imagery is often used because of its ability to cover large areas, but the spatial resolution often precludes fine-scale analysis. Furthermore, maps of insect-caused t...
متن کاملMountain Pine Beetle Epidemiology in Lodgepole Pine
The following brief synthesis of mountain pine beetle epidemiology is based on host-beetle interaction. In the first part I briefly describe the relationship between the dynamics of lodgepole pine and mountain pine beetle. The second part describes the phases in the infestation cycle and their main characteristics. This synthesis is based on published information on infestation behaviour in wes...
متن کاملSpatiotemporal analysis of remotely sensed Landsat time series data for monitoring 32 years of urbanization
The world is witnessing a dramatic shift of settlement pattern from rural to urban population, particularly in developing countries. The rapid Addis Ababa urbanization reflects this global phenomenon and the subsequent socio-economic and environmental impacts, are causing massive public uproar and political instability. The objective of this study was to use remotely sensed Landsat data to iden...
متن کاملIntrinsic and extrinsic determinants of mountain pine beetle population growth
1 Mountain pine beetle Dendroctonus ponderosae populations have large, economically significant outbreaks. Density dependence and environmental variability are expected to have important effects on their dynamics. We analysed time series data from an outbreak in the 1930s to determine the relative importance of population density and environmental variability on local population growth rates. 2...
