|Ground spraying to remove competing vegetation prior to planting (MNDNR)
There are a wide array of silvicultural activities that can be used in
established red pine stands. These activities may be aimed at controlling
stand density, increasing growth, improving tree form and quality, or
controlling competing vegetation. We discuss these activities separately
from those focused on regeneration because they are generally aimed at
achieving objectives other than establishing a new cohort of trees. This
is not to say that establishing new seedlings of red pine, or other tree
species, would never be an objective in established stands. In fact, this
may be an objective (see Managing for ecological objectives), in
which case certain stand tending activities, for example thinning, might be
combined with regeneration practices (see Regenerating red pine) to
establish new trees in the understory.
In this section, we highlight the
primary silvicultural tools you might use in established stands, with
specific reference to application in red pine forests.
You should also
refer back to applicable, but more general topics in Forest Management 101,
for example control of competing vegetation (Weeding and Cleaning).
