Some of these species are reported as invasive in Hungary for the first time, compared to previous published lists, such as that described previously in EPPO RS 2006/093:
- Azolla mexicana was previously not recorded in Hungary and is not known as invasive in other countries of the EPPO region,
- Azolla filiculoides was only considered casual in Hungary and is already known as invasive in the western area of the EPPO region,
- Cabomba caroliniana was not recorded in Hungary and is known as invasive in the Netherlands and in the United Kingdom.
- Elodea nutallii was recorded as casual in Hungary and is known as invasive in many countries of the north-western part of the EPPO region.
Of particular interest are the two climbers Echinocystis lobata and Humulus japonicus, which are not widely distributed in the EPPO region and may therefore represent emerging invaders.
