appreciable popularity in recent
years. Presently there are ap
proximately 45 colleges and

regional contests in the fall to
determine which schools will
represent their region the
following spring in the national
contest.
Students benefit from this
activity by gaining a much better
understanding of the soil, its
characteristics, and its
capabilities.

plete cutting of mixed oak
hickory forest plots, regeneration
from root sprouts is exceedingly
rapid, says Dr. Robert D.
Shipman, ecologist for the School
of Forest Resources at The
Pennsylvania State University.
Such sprouts from dormant
buds on freshly cut stumps serve
as a major source of browse for
deer and as natural seedlings for
a new stand of timber, Dr.
Shipmanpointed out recently from
field experiments at Penn State.
The amount and kind of
hardwood sprouts that develop
after clearcutting are highly
variable he said, and depend
upon the quality of the site, its
soil nutrient and water holding
capacity, and upon the inherent
sprouting ability of the species.

Clearcutting for Hardwoods
BROWN & REA, INC.
Most hardwood growth after
clearcutting, he added, is
produced by species responding
best to full sunlight-such as the
oaks and hickories. Results from
small blocks of clearcuttings
showed that scarlet oak produced
the largest sprouts. However,
white oak sprouts produced the
highest number of sprouts per
stump and per acre.
The site is located in Penn
State’s Stone Valley Ex
perimental Forest, Huntingdon
County, and was clearcut in 1965.
Deer browse began to increase
the first growing season after
cutting and increased gradually
until 1970. By that time, prac
tically all species exceeded 7 feet
in height and were beyond the
reach of deer.
From a timber growing
standpoint, it is still too early to
determine how cutting has af-

fected the final species makeup
of the new hardwood forest. New
trees growing from stumps have
not yet reached the poletimber
category, 3 to 5 inches in
diameter.
Dr. Shipman indicated,
however, that the new oak forest
should be adequately stocked
with trees. He assumes that at
least one sprout per stump will
become dominant within the next
five years, with each of these
young trees occupying sufficient
growing space.
To assure maximum
development, a “weeding” of the
sapling stand is desirable For
example, sprouts of undesirable
species, where they are growing
taller than desirable “crop”
trees, should be removed-thus
freeing desirable stems and
improving growth of the new
forest.
The forest ecologist and his
associates have found that
hardwood seedling sprouts in
clearcut areas develop mostly
from stumps 4 to 12 inches in
diameter-or from stubs less than
2_ inches in diameter. The
remaining natural seedlings on
clearcut areas germinate from
seed stored in the forest floor.
Research was begun 10 years ago
to determine the effects of
complete tree removal on timber
wildlife relationships.
Since oaks and hickories are
heavy-seeded species, very little
if any seed in the test area was
blown there from adjoining uncut
areas. Thus, practically all of the
natural reproduction developed
from root sprouts.
Dr. Shipman and associates
will continue to study the growth
of trees and other plant species
invading clearcut areas. Present
research is investigating changes
in nutrient distribution, soil
characteristics, and soil moisture
conditions limiting the rate of
regrowth on clearcut areas.
Clearcutting of eastern hard
woods is done mostly on small
plots of five to 20 acres. This is
not to be confused with clear
cutting of western conifers where
slopes are steep and clearcut
blocks often exceed hundreds of
acres.

second event in the 48th annual
Dairy Exposition ending
Saturday.
Trophies were to be presented

scheduled for Saturday was the
