Ribbed bog moss grows on peat and other organic soil layers more often than on downed bark or wood, but is reported growing on woody debris or other dead wood in a few locations.
32.
There are hollows colonised by bog asphodel ( " Narthecium ossifragum " ) and moss " Campylopus atrovirens " and the bog moss " Sphagnum contortum " also occurs.
33.
Ribbed bog moss grew on peat of all particle sizes but was most frequent on small ( 0.5-1 inch ( 1.25-2.5 cm ) ) peat particles.
34.
In a study of alpine mires in Italy, ribbed bog moss was intermediate in mire pH and mineral content compared to associated nonvascular and vascular plant species, occurring on both poor and rich mires.
35.
Ferns and gorse are common too, and in areas where peat has been cut in the past, there are bog mosses, the bog bean " Menyanthus trifoliata ", and marsh pennywort.
36.
There are also areas of grassland and a secondary woodland of downy birch, " Betula pubescens ", with a groundcover of rush, bog mosses and purple moor-grass, " Molinia caerulea ".

It is joined at West Charity Farm by Sleightholme Beck, its main tributary, which runs north-east from its source between Bog Moss and Sleightholme Moor where it is formed by the confluence of Dry Gill and Frumming Beck.
38.
Ribbed bog moss was found on downed woody debris in a mixed quaking balsam fir ( " Populus tremuloides-Betula papyrifera-Abies balsamifera " ) forest in east-central Alberta and on stumps in a mixed-hardwood forest in Wisconsin.
39.
On mires across British Columbia and Alberta, ribbed bog moss grows in mires with broad ranges of water pH and electrical conductivity, but is most common on strongly acidic peatlands ( water pH < 5.5 ) with moderate calcium and magnesium levels ( < 200 �S / cm * * ).
40.
Black bogrush ( " Schoenus nigricans " ) are prominent in the wetter, more base-rich parts, whereas bog mosses ( " Sphagnum spp . " ) and the insectivorous round-leaved sundew ( " Drosera rotundifolia " ) can be found in the wet hollows.
