Notes hydridization occurs between taxa ("a hybrid swarm").

The Condition and Trend of Aspen Communities in Kootenay and Yoho National Parks: Implications for Ecosystem Management and Ecological Integrity. Report to Parks Canada, Kootenay National Park and Yoho National Park. Utah State University, Logan, Utah, USA.
Unpublished report. Abstract only available. Contends that aspen does not reproduce from seed, but only from clones. Hence, aspen on burned areas is derived from clones that were there prior to fire, not from seed set after fire.

Ungulate Herbivory on Utah Aspen: Assessment of Long-term Exclosures. Journal of Range Management 53:145-153.
Examine data from exclusion plots. Conclude that climate does not affect aspen regeneration. Livestock browsing and big-game browsing (deer and elk) are advanced as major controls on regeneration. Regeneration most pronounced on plots where grazing excluded.

Kay, C. E., B. Patton, and C. A. White 1994
Assessment of Long-term Terrestrial Ecosystem States and Processes in Banff National Park and the Central Canadian Rockies. Report to Parks Canada.
AEU SCI QH 77 A3 K235 1994 Contends that aspen in the Canadian Rockies does not establish from seed but from clones. Suggests that the clones have survived through the entire Holocene, i.e., that they may be 10,000 years old. Contends that under the present situation in Banff Park, aspen is "approaching ecological extinction" (p. xiv).
