|Scientific Name:||Orthotrichum scanicum Grönvall|
Orthotrichum leucomitrium Bruch & Schimp.
Orthotrichum lewinskyae F. Lara, Garilleti & Mazimpaka
Orthotrichum holmenii from Kazakhstan shows that this taxon is conspecific with O. scanicum.
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Bryophyte Specialist Group|

The knowledge of the distribution of O. scanicum has improved significantly in recent years. It has been collected in many new localities and re-found at other older ones. Moreover, the size of several known subpopulations is very large, and it seems that previous considerations about this taxon being threatened were based on imperfect knowledge regarding its status. Hence the status of this species is changed to Least Concern.

|Range Description:||A large number of recent reports of O. scanicum and the examination of herbarium specimens have expanded the limits of distribution for this species considerably in the Mediterranean and Caucasian regions. In addition, the revision of the original collections of O. holmenii from Kazakhstan shows that this taxon is conspecific with O. scanicum. However, the name scanicum is older than holmenii. Today O. scanicum appears to occur throughout a wide circum-Tethyan area, including southern and Eastern Europe (Garilleti et al. 1999; Lara et al. 2001, 2003), northern Africa (Garilleti et al. 1997, Draper et al. 2003), Turkey (Erdag et al. 2004), and Georgia. However, it also spans a great part of central Europe and southern Fennoscandia, even if the subpopulations in some of these areas have vanished in recent years. It seems to have its optimum centre of occurrence in the mountainous areas of the Mediterranean Region, where it is frequent and abundant and colonizes several phorophytes (Draper et al. 2003; Erdag et al. 2004; Garilleti et al. 1999; Lara et al. 2001, 2003).|
Since the initial evaluation of the conservation status of this species our knowledge of the distribution of O. scanicum has remarkably improved. It has been collected in many new localities and re-found at other ones. Moreover, the size of several known populations is significant, so it seems that previous considerations were based on imperfect knowledge regarding its status.

|Population:||O. scanicum is no longer considered a rare moss in the mountains of the Mediterranean and the Caucasian regions, as it can be locally abundant in some forests, such as those of the Rif mountains in Morocco (Draper et al. 2003), or frequent in large areas, such as the Pyrenees (Garilleti et al. 1999), northern Greece (Lara et al. 2003) or northern Turkey (Erdag et al. 2004). However, in northern Europe it is still very rare and has not yet recovered from past decline.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It grows on trunks and branches of conifers as well as broad-leaf deciduous trees; is very rarely found on rocks (Garilleti et al. 1999).|
|Generation Length (years):||5|
|Major Threat(s):||Although there were past threats to this species in the northern European part of its range (logging and pollution), in the southern and eastern parts of its range there are no significant threats.|
|Conservation Actions:||Given its wide range this species must occur in a large number of protected areas.|
