Tree loss is increasing rapidly due to drought- and heat-related mortality and intensifying fire activity. Consequently, the fate of many forests depends on the ability of juvenile trees to withstand heightened climate and disturbance anomalies. Extreme climatic events, such as droughts and heatwaves, are increasing in frequency and severity, and trees in mountainous regions must contend with these landscape-level climate episodes. Recent research focuses on how mortality of individual tree species may be driven by drought and heatwaves, but how juvenile mortality under these conditions would vary among species spanning an elevational gradient—given concurrent variation in climate, ecohydrology, and physiology–remains...

Temporal dynamics of each GCPO priority system are recognized as important contributors to the overall system integrity. The Integrated Science Agenda (ISA) alludes to the desired condition that forest structure should be dominated by mature upland hardwood stands across the greater landscape. However, to ensure future forest sustainability a small portion (≤10% of the landscape) should be in a state of regeneration, or early forest succession. The ISA provides this endpoint as a general target, but lacks specificity regarding the desired composition of forest stand ages because there is limited literature available that assesses upland hardwood stand age from an ecosystem integrity perspective. Priority wildlife...
