This thesis investigates the patterns, causes and consequences of bryophyte distributions in Lancashire (north-west England). At a habitat scale, it is shown that species are spatially clustered and exhibit similarities in their ecologies within clusters, related in particular to gradients in disturbance and soil moisture. At a landscape scale. altitude is most strongly associated with differences in species distributions, correlated with important changes in habitats, water availability, nutrient availability and substrate pH. Changes in the solid geology also had an important influence in North Lancashire, where large exposures of limestone exist. Also at a landscape scale, high species-richness was found to be associated with high water availability, low nitrogen deposition and high cover of broad-leaved woodland.
