Spatial units description
Spatial units are delineated based on biogeographic regions of the world. The range of this plant is circum-boreal and assessments of both its status and ecological functionality are meaningful only at this level.

Ecological Function
Functionality description
Functionality at a spatial unit level would be demonstrated by evidence that either (or both) sexual and/or asexual propagules travel between subpopulations within metapopulations. In highly natural systems, metapopulation interactions are evident from the existence of transient sub-sites, and their recurrence after local extinction. Another important indicator is the existence of keystone sites that supply propagules for transport to other sub-sites within a metapopulation via dispersal processes. At the spatial unit level, this functionality needs to be demonstrated within and between a significant majority of metapopulations. This may not be straightforward but confirmation of active metapopulation dynamism may be inferred when subpopulations are genetically diverse. Generally, however, confirmation of any form of recruitment will usually suffice and this may be inferred from increases in the sizes of subpopulations (including temporary ones) and the observation of new stands. Observation of active dispersal processes (e.g. geomorphological and animal movement links) within the geographical limits of a metapopulation are also indicative of functionality. The scale of observation is of course crucial; the species is so widespread that metapopulation functionality will only be observable between groups of sub-sites (and potential new sites) within the range of influence, and at the scale, of the dispersal processes (e.g. ranging distances of epizoochorous vectors, catchments of rivers, etc.) which can vary hugely.
