The Upper Tisa Valley. Preparatory proposal for Ramsay

Part 2.
The flora and vegetation of the Hungarian section
of the River Tisa valley, from Tiszabecs to Tokaj
This part contains, in separation, the vascular flora & vegetation the Hungarian
section of the River Tisa valley from Tiszabecs (Ukrainian - Hungarian Border) to the
Tokaj region.
The reasons for the separation are:
1. – Drăgulescu, C. and A. Mihály used a different taxonomy-system from what
we use. We followed the Soó system with their species-numbering. Moreover,
separating these two parts from each other seems to be reasonable for another reason:
the Upper Tisa section has more natural flora & vegetation while the Hungarian
section has a richer one with weeds and introduced species in abundance.
2. - For this reason we made a classification of the flora of this section
following Simon (1988, 1991, 1992). The table shows the Nature Conservation ranks
of the vascular flora of the Hungarian section of the River Tisa valley from Tiszabecs
to Tokaj.
