The Role Of Disease & Insects In Aspen Ecology, John C. Guyon Ii
The Role Of Disease & Insects In Aspen Ecology, John C. Guyon Ii
Aspen Bibliography
Aspen is a keystone species in montane forests, and enhances a number of key resource values including wildlife habitat, water resources, and fire behavior. Recently, aspen forests have experienced episodes of dieback and decline across western North America (Worrall et al. 2010, Guyon and Hoffman 2011). A large proportion of the dieback and decline has been linked to drought stress or drought-prone locations (Hanna and Kulakowski 2012). However, insects and diseases are commonly found in declining aspen stands, leading to confusion about the role of insects and diseases in aspen ecology. Additionally, aspen has a reputation for being susceptible to …
Aspen Ecology And Management In The Western United States, Norbert V. Debyle
Aspen Ecology And Management In The Western United States, Norbert V. Debyle
Aspen Bibliography
Quaking aspen occurs on more than seven million acres of the interior western United States. It is seral in most sites, usually giving way to more shade-tolerant conifers. Regeneration is almost exclusively by root suckering -- seedlings are a rarity. Discrete clones that occupy several acres are the rule on mountainous western landscapes. Management practices reflect the values of this ecosystem. These values, in decreasing order of importance, are: livestock forage, wildlife habitat, watershed cover, esthetics and recreation, and wood products. Wood products are gaining in importance, thus encouraging more active management of this important type.

Aspen Grove Use By Deer, Elk, And Cattle In Southwestern Coniferous Forests, Hudson G. Reynolds
Aspen Grove Use By Deer, Elk, And Cattle In Southwestern Coniferous Forests, Hudson G. Reynolds
Aspen Bibliography
Aspen groves within mixed conifer forests produce more herbaceous understory than adjacent forest. Thinning aspen groves improves herbaceous understory and aspen regeneration. Higher deer and cattle use of aspen groves is associated with the greater abundance of understory vegetation.
