Mean and standard error of the environmental parameters at all the altitudes studied. analysis plant species recorded were assigned to fteirrespective life-fonn based on Raunkiær classifications following Ostenfeld’s, (1905- ' 908) divison ofthe Faroese flora. To assess ^hether our data was representative for ^aunkiær biological spectra for the Faroese Oora, we calculated the number of vascular P'ant species belonging to each life-form type as a percentage of the total number of vascular plant species on all the five stud- ied mountains. This was then compared with the distribution of Raunkiær’s life-forms in the whole of the Faroese flora (Raunkiær, 1934), allowing us to determine if the life- form data from our study showed the same trends and, thus, is representative of the flora in the Faroe lslands. Correlations between life-forms and the environmental parameters were tested using
