Description :
The AA. studied relationships between geomorphic and riparian factors and large wood (LW) and large-wood jams (LWJ) structure in different geomorphic settings associated with old-growth and second-growth settings in the Porcupine Mountains along the south shore of Lake Superior. The analyses suggest differences in relationships between geomorphic factors and LW and LWJ structure. Channel width, distance from headwaters, gradient and sinuosity were identified by regression tree analysis as the most important variables for predicting LW characteristics, while channel width and confinement were the most important variables for predicting LWJ characteristics.
