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
