Abstract

The AA. develop and test a methodology to : 1) predict the occurrence of palsas, earth hummocks, sorted solifluction sheets and periglacial deflation sites in a subarctic landscape and 2) determine the most important environmental factors affecting the distribution of these features at the landscape scale. The study was performed using an empirically-derived data-set of landforms from an area in northern Finland. Logistic regression and hierarchical partitioning were used to analyse the data and the predictive performance of the models was evaluated using area under the curve (AUC) measures. The results encourage further application of the grid-based modelling approach
