blocks; 2) commercially-grown potted aspen seedlings that were planted in an
<br />unirrigated fenced area approx 1 km from the irrigation study site, and; 3) natural
<br />aspen sprouts growing in an un-mined area of the Yoast mine that had been Geared
<br />of mature aspen. None of these study sites were replicated, so the survival, growth,
<br />and water status ftndings are applicable only for that site; and comparability of
<br />different un-replicated treatments within the same site must be made with caution.
<br />Although the commercially-grown potted aspen trees were planted on stored soil, it
<br />was not determined if the roots grew out of the potting mix into the stored soil during
<br />this first year of study.
<br />Natural sprouts were growing at random spacing, about 1 ft to 8 ft apart. Natural
<br />sprouts selected for measurement were thinned to no closer than 5 ft spacing. The
<br />potted and natural trees in all locations were from unknown genotypes, likely
<br />different from the irrigated study transplants. Each plant was labeled with an ID
<br />number: xx-yy, where xx =treatment (01-12) and y =plant number (01-50).
<br />
<br />Treatment codes are as follows:
<br />1. 2W mine, fenced site 1, transplanted sprouts, fresh topsoil, high irrigation
<br />2. 2W mine, fenced site 1, transplanted sprouts, fresh topsoil, medium irrigation
<br />3. 2W mine, fenced sfte 1, transplanted sprouts, fresh topsoil, no irrigation
<br />4. 2W mine, fenced site 1, transplanted sprouts, fresh topsoil, low irrigation
<br />5. 2W mine, fenced site 1, transplanted sprouts, stored topsoil, medium irrigation
<br />6. 2W mine, fenced site 1, transplanted sprouts, stored topsoil, no irrigation
<br />7. 2W mine, fenced site 1, transplanted sprouts, stored topsoil, high irrigation
<br />8. 2W mine, fenced site 1, transplanted sprouts, stored topsoil, low irrigation
<br />9. 2W mine, fenced site 1, root segment sprouts, fresh topsoil, no irrigation
<br />10. 2W mine, fenced site 1, root segment sprouts, stored topsoil, no irrigation
<br />11. 2W mine, fenced site 2, planted potted seedlings, stored topsoil, no irrigation
<br />12. Yoast mine, not fenced, natural sprouts, natural topsoil, no irrigation
