Wood sorrel (Oxalis acetosella) is an occasional herb on Watershed 6.  It is more common toward the higher elevations in the spruce-fir-white birch forest. However it can be found throughout the watershed. It is often associated with rock outcrops, or found near streams or in or near very rotten logs. Since litterfall tends to completely cover up this species each year, areas where litter may not accumulate as deeply may be areas where wood sorrel can better survive. In the photo below it is in a cluster of rocks near the stream.
