Changes in forest structure and shifts in tree species composition have occurred globally due to climate change and altered disturbance regimes. With climate trending toward warmer and drier conditions, these altered forest communities may reorganize in diverse and unpredictable ways. This is especially true in mountain environments where a range of vegetation types and abiotic conditions coexist. In this study, we used long-term permanent plot data from a site spanning broad environmental gradients to assess regeneration and mortality patterns in populations of aspen (Populus tremuloides)....

National forests and grasslands are popular recreation destinations. Providing opportunities for visitors while protecting these natural attractions falls under the scope of recreation planning, but for recreation planners to do their jobs effectively, they need data—information that includes visitor demographics, reasons for visiting, and where visitors are coming from. Increasingly, recreation planners are using real-time visitor data from posts and photos of trip activities posted on crowdsourced platforms, such as social media or citizen or community science projects, to inform...
