Bryophytes in Second and Old Growth Forests

I'm interested in bryophyte communities...which bryos like to hang out together...not only, say on a log, but in an ecological community as well....in a rich fen, or in  an oak-hickory woods for example. The following two illustrations show a generalized 'map' of the commonly found bryophytes in a second growth woods and an old growth woods.

Common Bryophytes of Second Growth Hardwood Forests

Common Bryophytes of Old Growth/Rich Woods

One of the things you'll notice is that the diversity is greater in the old growth compared to second growth woods. Also, due to high amounts of leaf litter, there are virtually no bryophytes on the ground.  Of course there are many more species found than illustrated here, but these are the species you are likely to run into in  these areas.

In my next post, i'll show some maps from specific places.
