“…Human desire for large ungulates for subsistence, aesthetics, or recreational purposes, while simultaneously eliminating key predators, in some locales, has resulted in runaway populations and concomitant vegetation impacts [43], such as the changes in understorey vegetation implicated here. In areas, undergoing rapid climate warming such as the broad region of the current study, combined effects of extended drought and herbivory are particularly detrimental to sustained aspen communities [19,24,49]. Third, we have seen here that understorey plant assemblages (and presumably dependent fauna) will be altered by aspen's response to human decisions-in cutting, recreational use, herbivore management, and other developments (i.e., roads, houses, campgrounds, and trails)-in the form of canopy openings and varying degrees of recruitment success.…”

“…Future management actions within Pando, using the wisdom of hindsight alongside results here, would do well to manage stable aspen within functionally appropriate aspen prescriptions [4]; meaning selection and group tree felling would promote more resilient uneven-aged forests. Second, herbivory is now a common threat to survival of aspen forests, not only in North America, but across Europe as well [10,32,48,49]. Human desire for large ungulates for subsistence, aesthetics, or recreational purposes, while simultaneously eliminating key predators, in some locales, has resulted in runaway populations and concomitant vegetation impacts [43], such as the changes in understorey vegetation implicated here.…”

“…Trembling aspen (Populus tremuloides Michx) is an ecologically and commercially important tree species with high genetic diversity and a broad natural range, including the boreal forest of North America, the eastern United States, and the western mountain ranges from Mexico to Alaska [1,2]. Aspen can regenerate both via sexual and asexual reproduction [2,3] Competing interests: I have read the journal's policy and the authors of this manuscript have the following competing interests: AH received a research grant that included matching financial contributions from industry partners to a government research grant for this study.…”

“…Populus davidiana (David's aspen), one of the six aspen species (Populus spp.) across the world, is a deciduous tree of the family Salicaceae and is widely distributed in eastern Asia (northeast China, Korean peninsula) [16]. The harvest rotations of P. davidiana are generally short and the fast growth facilitates commercial forestry, so it is widely planted in China through the encouragement of government programs targeting conversion of crop lands to forest cover [17].…”

“…All these provide a basis for the protection and utilization of P. davidiana. However, Rogers et al [16] highlighted that climate warming is one of the common threats to aspen ecosystems from a global point of view for six aspen species by means of a qualitative survey and systematic literature analysis. Although Zhao et al [29] took a preliminary step in this area and suggested that moderate drought may favor quick regeneration of P. davidiana based on monitoring of past community data, few studies have explored its vulnerability under future climate change.…”
