“Combining
single-tree selection with group selection … may work to maintain some vertical structure while permitting

“One kind of structure that may have promise for
production and long-term
maintenance of owl habitat is a multi-aged mosaic of small, even-aged groups or aggregations … in size from
about 2 acres down to a
quarter-acre, or possibly less. Probably this type of structure best approximates presettlement stand
structures, thus warranting
serious consideration.” (p. 271)
“Management plans should focus on addressing undesirable
trends, designing potential
solutions, and proceeding experimentally to implement those plans on the landscape.” (p. 273)
