The structural simplification of selection forests demonstrates
that retention of structural attributes should be considered in
treatment prescriptions for uneven-aged silvicultural systems
where appropriate. However, in this context the term ‘‘retention’’
implies that an attribute that would be removed under conventional
management is deliberately retained for conservation
purposes. This is fitting for most structural attributes retained in
a modified clearfelling system, such as variable retention harvesting.
The term is less appropriate for selection systems. In these
