Forest slash burning effects to be studied
A new Oregon State
University research pro
ject is aimed at developing
a system for predicting the
effect of residual smoke
from forest slash burning
on air quality
The system will provide
guidelines for scheduling
and regulating prescribed
slash burning in moun
tanious areas of the Nor
thwest
“ It will enable forest
slash — residue from logg
ing operations — to be
burned in such a manner as
to minimize the air pollu
tion impacts on smoke sen
sitive areas,“ says M A
( Mike) Wolf, associate pro
fessor in the department of
atmospheric sciences and
principal investigator for
this Air Resources Center
research program
The study is funded by
the U S Forest Service’s
Key to producing more ‘10s’

Cloning may help the
Northwest’s $40 million a-
year Christmas tree in
dustry produce more 10s
Prospects are good for
improving and steadying
the quality of Douglas F ir
Christmas trees by grow
ing them from cuttings
taken from high-quality-
trees instead of from seeds,
according to Oregon State
University horticulturist
Bill Proebsting
“ W ere hoping this will
substantially raise average
tree quality although the
odds of every tree becom
ing a 10 are small,” Pro
ebsting said.
The researcher is involv
ed in a seven year old clon
ing study in itiated by
retired OSU horticulturist
Al Roberts and funded by
OSU’s horticulture depart
ment and the Northwest
Christmas Tree Associa
tion

All methods of growing
plants without using seeds,
such as rooting and grow
ing cuttings, buds and
tissue cultures, are cloning
techniques, the researcher
explained
Cloning Christmas trees
produces genetically iden
tical trees and would help
growers avoid the varia
tions in quality that appear
in stands of Christmas
trees grown from seeds, he
said

An evaluation committee
participating in the study

old Christmas trees cloned
from cuttings an overall
quality rating of 7 or better
on a scale of 1 to 10 With
the same rating system,

There are obstacles, the
researcher pointed out
