The process of recreating historical land cover dynamics, needed to nderstand trends and transient states in ecosystems, includes ifficulties such as the sensitivity of applied spatial analyses to eterogeneities in historical material. This paper compares the handling f quantitatively dominating categories in two matrix analyses of land over change within a Swedish boreal landscape (1725-1859). The focus is n how inconsistencies between historical maps can be handled without iolating the inherent semantic potential. The study shows that analyses f land cover support different indications of change depending on the reatment of dominating categories. The type of landscape and research uestions in focus should therefore be part of choosing matrix method nd classification scheme. The observed patterns need to be evaluated gainst drivers of change and semantic plasticity in classification chemes to separate ecological change from semantic confusion. This aper recommends aggregated classification schemes with maintained riginal relationships between categories in comprehensive analyses. owever, no pathway is persistent over time and categories should be llowed to disappear and new to appear. Analysis of historical dynamics ith extended transition matrixes is recommended to account for the ynamics of small categories in relation to dominating categories within landscape.
