Assessment Notes
Taxonomic notes
Why suggested for a Global Red List Assessment?
A globally rare species with very restricted habitat requirements (coniferous trees close to waterfalls and rapids). Proposed by Göran Thor.
Suggested assessment by proposer:: EN on the A criterium (A2bc), population decrease 80 (30-90) % the last 50 years in Sweden, population decrease the coming 100 years 30 (25-50) %.
Geographic range
Lobaria hallii is widely distributed in northern Europe eastwards to the Ural Mountains and in North America but there are few localities (9 in Sweden, a few in Norway, Finland, Russia and North America.
Population and Trends
The species has decreased in all of its distribution area and is red-listed in e.g. Finland, Norway and Sweden. The population is estimated to have decreased with 80 (30-90) % the last 50 years in Sweden.
Population Trend:
Habitat and Ecology
The species is found on branches of coniferous trees close to water falls or rapids where the humidity is constantly extremely high. The species is only found on localities with long tree continuity.
Threats
Forestry and building of hydro-electric power stations are threats. The distribution is fragmented which might also be a threat.
Conservation Actions
All remaining localities should be protected. Building of hydro-electric power stations should not be abandoned up-streams current localities
