Kingdom Phylum Class Order Family
Plantae Marchantiophyta Jungermanniopsida Jungermanniales Jamesoniellaceae

Scientific Name: Jamesoniella undulifolia
Species Authority: (Nees) K.Muell.

Assessment Information [top]

Red List Category & Criteria: Vulnerable A1ac ver 2.3
Year Published: 2000
Date Assessed: 2000-01-01
Annotations:
Needs updating
Assessor(s): Bryophyte Specialist Group
Reviewer(s): Hallingbäck, T., Hodgetts, N., Geissler, P. & Tan, B. (Bryophyte Red List Authority)
Justification:
A decline of populations has occurred in at least part of its distribution area, and more than 20% of its populations have probably disappeared within the last 30 years (three generations). This species therefore meets the IUCN criteria for Vulnerable.

Geographic Range [top]

Range Description: Several old localities are known but it has disappeared from most of these in Europe; very few sites are unspoiled today except for several recently found sites in northern Asia (Siberia, Chukotka, Kamchatka, Manchuria) where it may be more common than is currently known.
Countries occurrence:
Native:
Austria; China (Heilongjiang, Jilin, Liaoning); Czech Republic; Denmark; Finland; France; Germany; Greenland; Korea, Democratic People's Republic of; Norway; Poland; Russian Federation; Sweden; Switzerland; United Kingdom (Great Britain)
