In the new publication, researchers have emphasizes on the idea of Mega conservation of widespread, common species like Aspen over traditional and single-species conservation. Aspen forests have been greatly affected by favoring high-value timber trees, domestic and wild herbivore mismanagement, fire suppression, mining, etc.  Fourteen leading aspen ecologists from eight countries were assembled to the issues related to Aspen. Aspen forest is not the only potential ” Keystone communities” that require Mega conservation.  Sage-steppe lands in Europe and North America, vast taiga forests of Eurasia and Eucalypt forests across Australia are other potential “Keystone communities.”
