These maps have been digitized along with maps of environmental factors (topography, soils), disturbance (1938 hurricane, historical land-use), and silvicultural treatments.
Modeling of aboveground woody C in the entire wildland acreage was done using multivariate linear regression with up to four environmental variables (topography, habitat, soil and ranch).
Furthermore, the controlling environmental factors of topography, land use, climate and soils at the catchment level are seldom analysed.
Proximity to capable faults, seismicity, availability of cooling water, population, flooding, topography, environmental sensitivity, proximity to national borders, electrical grid, transportation opportunities and hazardous facilities were chosen as screening criteria.
For the geospatial modeling, we used soil profile observations (585 for SOC stocks and 153 for active-layer thickness) and environmental variables (climate, topography, land cover, and surficial geology types) and generated fine-resolution (50-m spatial resolution) predictions of SOC stocks (to 1-m depth) and active-layer thickness across Alaska.
We examine the impact of spatial scale (1 km, 250 m, 10 m), environmental metrics (climate, topography, soils), and species overlap for 11 rare and endangered species in the dry forest of Oahu, Hawaii, which is one of the world's most endangered ecosystems, and contains some of the highest resolution data on species locations and environmental metrics for an oceanic island.
Plant communities were classified using TWINSPAN and the effects of environmental factors (soil, topography, current management and habitat continuity) were analysed by canonical correspondence analysis and regression analysis reducing for the effects of spatial autocorrelation by using principal coordinates of neighbour matrices.
The environmental setting and topography of the area are generally sloping towards east to south-east.
In comparison, biophysical aspects of vulnerability refer to topography, environmental conditions, land cover or hazards like earthquakes, storm or sea level rise.
However, tree height as the best variable for interpreting species diversity may suggest that forest structural complexity plays a more foundational role for species diversity, as tree height is a direct indicator of structural complexity (Franklin et al. 2002), which echoes forest development and succession, and also the limits of environmental conditions and topography.
