Assessment Notes

R-L categories correct, but text here does not match final assessment. Updated version will be published in IUCN´s Red List June or Nov 2019.

Justification

Gyroporus punctatus is a very rare ectomycorrhizal species known only from the south of Russian Far East and Japan. This unusual little bolete having characteristic appearance is associate with Quercus and has been found only in mature broadleaved forests. At present only 5 localities in Primorsky krai of Russia and 7 localities in Japan are known. This species is endangered because the area of natural habitats is noticeable reduced in recent years due to several reasons (human impact - ongoing intensive forest cutting, drying caused by probably climate change.
Preliminary assessment: in sum 12 localities is known; the total population is estimated approx. 100, what is correlated with 1000 mature individuals (low fragmentation of functional individual).  It leads to Vu under criterion D1 and C2a(i).

Why suggested for a Global Red List Assessment?

Gyroporus punctatus is a very rare species known only from the south of Russian Far East and Japan. It can be found only in natural oak forests. This species is endangered because the area of natural habitats is noticeable reduced in recent years due to several reasons (human impact, drying caused by illness, and probably climate change). (Data on this species were compiled by Eugenia Bulakh)


Geographic range

Gyroporus punctatus is an East Asian species with a small areal.  It’s known from Prymorsky Krai of the Russian Far East and from Japan (Hokkaido, Ishikawa, Kyoto, Hyogo, Tottori). All area of occurrence is less then 35 000 km2.


Population and Trends

At present only 12 localities is known: 5 localities in Primorsky krai of Russia and 7 localities in Japan. In Russia this species is included in Red Data Book of Prymorsky Krai (2007) and because of this it has been specially monitoring during about 15 years,  but all the records received belonged to the same areas. So it’s hardly possible to have many unknown localities.  Regarding Japan there are 12 records from 1980 till 2015 which related with 7 localities noted above. The area of natural habitats is noticeable reduced in recent years due to ongoing intensive forest cutting, and besides a problem of oak drying from illness interrelated probably with climate warming.
Preliminary assessment: in sum 12 localities is known; the total population is estimated approx. 100, what is correlated with 1000 mature individuals (it’s supposed low fragmentation of functional individual).  It leads to Vu under criterion D1 and C2a(i).

Population Trend: Decreasing


Habitat and Ecology

It is an ectomycorrhizal fungus associated with Quercus (e.g. Q. mongolica). It prefers mountain and submountain oak forests, sometimes in lowland. Usually it produces 1-2 fruitbodies per locality, it supposed to be low fragmentation of functional individual.

Temperate Forest

Threats

Reducing of the oak forest area due to deforestation or drying caused by environmental and climate changes.

Unintentional effects: large scale (species being assessed is not the target) [harvest]Recreational activitiesDroughts

Conservation Actions

Organization of new protected areas containing known localities, preservation of oak forests, measures against oak drying.
