Učka Mt. as a model for monitoring of climate change impact on flora – preliminary research

We have analysed data gathered during the flora mapping of northern part of Učka Nature Park with respect to their areal and life forms, using MTB 1/64 quadrants as a basic spatial units. We wanted to test whether on Učka Mt. beside horizontal (elevational) gradient, horizontal (latitudinal) gradient exist as well, especially because of north-south orientation of Učka Mt. For shares of particular life forms and areals we have calculated Pearsons correlation coefficients with elevation, latitude and longitude. With the exception of therophytes, for all life forms correlations of same directions (positive or negative) have been established with elevation and latitude. Among them, those for phanerophytes which share decrease with increase of elevation (r=-0.8 ; p
