DISTRIBUTION AND OCCURRENCE
SPECIES: Pleurozium schreberi | Schreber's Moss 



GENERAL DISTRIBUTION : 
Schreber's moss is a widespread and common moss ranging from Greenland
to Alaska south (principally in uplands) to North Carolina, Tennessee,
Arkansas, South Dakota, Colorado and west to Washington, California and
Oregon.  It also is found in South America, Europe, and Asia [16,35].
It occurs in the Cordilleran Ranges and southward to Costa Rica,
Columbia, Ecuador, Peru, and Patagonia [35].  Schreber's moss is new to
Mexico, where it has been found on the Cofre de Perote Volcano [18].

HABITAT TYPES AND PLANT COMMUNITIES : 
Schreber's moss typically occurs as a dominant or codominant ground
cover in stands dominanted by white spruce (Picea glauca) or black
spruce (P. mariana).  The black spruce-Schreber's moss forest community
described by Foster [13] is the most widespread vegetation type in
southern Labrador and occupies a wide range of sites from poorly drained
outwash plains to convex slopes and hill crests.  In the black spruce/
bog blueberry (Vaccinium uliginosum)-bog Labrador tea (Ledum
groenlandium)/Schreber's moss community type described by Foote [12],
Schreber's moss commonly covers about half of the forest floor.
Published classification schemes idenitifying Schreber's moss as a
ground cover dominant or codominant are as follows:

Some forest types of central Newfoundland and their relation to
  environmental factors [7].
Forest community types of west-central Alberta in relation to selected
  environmental factors [6].
Classification, description, and dynamics of plant communities after
  fire in the taiga of interior Alaska [12].
A review of forest site classification activities in Newfoundland and
  Labrador [25].

  Alaska [28].
