Summer climatic influences on Pinus ponderosa planted on mined lands in eastern Montana.

Seedlings did not survive 6 wk of drought in 1981. Of the 1- and 3-yr old seedlings planted in 1982, 89 and 88%, respectively, survived through 1983 despite above-average temperatures and below-normal precipitation in July and August. High survival was attributed to seedling quality, favorable precipitation patterns and lower temperatures during the first summer of seedling establishment.-from Authors
