ENVIRONMENTAL CONSEQUENCES in rocky mountain coniferous ...

RESULTS
Planted
Planted seedlings survived very well on areas that had been scarified or
burned, exceeding 95 percent at 3 years and R7 percent at 5 years (fig. 1). ?!@an-
while, their counterparts fared poorly in the residues-removed and chips-spread
treatments. A1 though planted seed1 i ngs in the residues-removed treatment were
surviving at the rate of over 90 percent at 3 years, they had declined rapidly to 59
percent survival two years 1 ater . Planted seed1 i ngs in the chi ps-spread treatment
declined in a similar fashion, dropping from 84 percent survival at 3 years to 49
percent at age 5.
