Taxonomic notes


Why suggested for a Global Red List Assessment?

A rare species with a small distribution area. Proposed and data compiled by Göran Thor.

Suggested assessment by proposer: EN on A3bc, population decrease 80 (50-90) % the coming 100 years.


Geographic range

The species is only found in Northern Europe. It is red-listed in e.g. Germany and Sweden.


Population and Trends

The total population is small and large part of its population is on Fraxinus excelsior. About 10 localities are presently known from Sweden.

Population Trend:


Habitat and Ecology

The species occurs on Fraxinus excelsior and more rarely also on Corylus avellana, Fagus sylvatica and Quercus spp. in ancient woodlands with long tree continuity not severely affected by air pollution.


Threats

Ash dieback is a major threat, but also forestry and air pollution.


Conservation Actions

All localities where the species occurs on other tree species than Fraxinus excelsior should be protected.
