Carex magellanica. Tall bog sedge.

Life-form & Growth Form:  

Hemicryptophyte. Herbaceous perennial. Rhizomatous, rhizome short-creeping.  

Flowering period: 

July and August.


Flushes within montane blanket bog. Upland sphagnum bogs. Wet level moorland. Clearings in swampy woods. 


Habitat loss and fragmentation through peat cutting, peatland drainage, encroachment of scrub and woodland, coniferous afforestation, and burning of bog vegetation. Eutrophication from adjacent intensive agriculture also threatens peatland habitat at many sites, allowing mesotrophic species to invade and dominate. The Garron and Sperrins populations are distant from one another, greatly increasing the risk of one or more further local extinctions within Northern Ireland. In addition, the Sperrins populations are also spatially segregated through habitat loss and fragmentation.
