In todays age the size is of little concern when it comes to logging.
Only the residual damage is increased with the size of the trees.
Bigger trees, biiger equipment, more damage unless increased care taken.

Selective harvest on steep slopes can cause enough site damage to equal
that of a clearcut, unless methods and techniques are designed for such
operations. In this as in any business there are those who can do it,
and those who don't care. Much depends on soil types, equipment used,
and the desire of the logger. There have been some efforts at baloon
and helicopter logging on extream sites, but some of our PNW observers
would need to comment on that aspect of logging.

Equipment demands on space and operational costs can limit the reduction
of clearcuts past a certain size, most sites need initial determinations
of methods and impacts prior to the sale. Many of the modern loggers
are taking this effort. In other words no clearcut (pun intended) answer
on smallest size.

Bottem line is, every job or site different, and the bottem line
determines methods, i.e., profit.
