Near Threatened. One species is Extinct at the <strong>European</strong><br />
level, the Serbian endemic Trapa annosa; however the<br />
taxonomy <strong>of</strong> the genus Trapa is far from clear and it is not<br />
certain that T. annosa is a good species. The Greek endemic<br />
Isoetes heldreichii, is listed as Critically Endangered/<br />
Possibly Extinct as it has not been seen since 1885, in spite<br />
<strong>of</strong> searches in the type locality, however there is also a need<br />
to resolve the taxonomic status <strong>of</strong> this species, particularly<br />
in relation to populations recently found on the island <strong>of</strong><br />
Lesvos (I. Bazos pers. comm. 2010).<br />

Finally, it should be noted that the percentages <strong>of</strong> threatened<br />
aquatic plants mentioned above represent minimum<br />
estimates. A more realistic value may be calculated based<br />
only on the surviving species which have been assessed for<br />
their extinction risk (i.e. omitting DD and EX from the<br />
total). In this case, 7.9% <strong>of</strong> aquatic plants are threatened at<br />
<strong>European</strong> level and 8.1% at EU 27 level. The Extinct and<br />
threatened species (Critically Endangered, Endangered,<br />
and Vulnerable) at <strong>European</strong> and EU 27 level are listed<br />
in Table 10.<br />
