Dwarf
Mistletoe Study Block

This is a
research block to compare and contrast five different
approaches to restoration in a stand with moderate to
heavy dwarf mistletoe infestations. Dwarf mistletoes
are parasitic seed-bearing plants that depend almost
completely on their hosts (ponderosa pine trees, in
this case) for water and nutrients. Though natural in
ponderosa pine forests, dwarf mistletoes cause infected
host trees to be slowly weakened and generally killed
(tree size/vigor dependent) as the trees are drained
of water and nutrients. The longevity of trees infected
with dwarf mistletoe becomes an important factor in
restoration considerations.
Five treatments
(and one control unit) are proposed: presettlement model,
uneven-aged model, Forests Forever (Southwest Forest
Alliance), a model targeting dwarf mistletoe specifically,
and prescribed fire only. All units, except the control,
will be prescribed burned. These units are grouped together
for quick visual comparison. For scientific comparison,
the treatments utilize a series of permanent plots that
capture a host of tree, soil, small mammal, and understory
data.
