Impacts of coarse woody debris and edge effects on Engelmann spruce regeneration
MetadataShow full item record
Engelmann spruce (Picea engelmannii Parry ex Engelm.) is a notoriously difficult species to regenerate, and there has been a history of regeneration failures following group selection cuts on the Uncompahgre Plateau. Our goal was to investigate edge effects and coarse woody debris management on regeneration success in group selection openings. Group selection is an uneven-aged system used in the West to regenerate high elevation spruce-fir forests with small (<1 ac) openings. We implemented an Engelmann spruce germination study on the Uncompahgre Plateau in group selection openings. Permanent ...
