Assessment Status Notes

Taxonomic notes

The name P. sieversiae has precedence over P. tatrensis Urban.


Why suggested for a Global Red List Assessment?

This is a well defined rust with characteristic teliospore morphology. There are only two known isolated sub-populations, one in North America (with roughly 6 specimens known from herbaria) and the other in northern Czech republic/southern Poland (with a further 5-6 specimens). The youngest known specimen is from 1965 from Utah, USA. The rust is autoecious on Geum sp. (G. turbinatum in NA, G. reptans in the Tatra mountains). The known hosts are uncommon, but not rare, and the scarcity of the rust does not appear to be on account of the rarity of the host plant.

Preliminary red list assessment: DD (Data deficient)
Lack of knowledge, not collected since 1965.


Geographic range

currently specimens exist from Poland, Czech Republic, Slovakia and north western USA.


Population and Trends

There are only around 12 specimens known worldwide (last known record 1965).

Population Trend:


Habitat and Ecology

appears to be restricted to Geum sp.

Temperate Shrubland

Threats

grazing of host plant

Nomadic grazing

Conservation Actions


Research needed

A targeted search for this species is recommended in the areas of know distribution of the host plant species.
