Gathering information about forest variables is an expensive and arduous activity. As such, directly collecting the data required to produce high-resolution maps over large spatial domains is infeasible. Next generation collection initiatives of remotely sensed Light Detection and Ranging (LiDAR) data are specifically aimed at producing complete-coverage maps over large spatial domains. Given that LiDAR data and forest characteristics are often strongly correlated, it is possible to make use of the former to model, predict, and map forest variables over regions of interest. This entails dealing with the high-dimensional (∼102 ) spatially dependent LiDAR outcomes over a large number …

Interactions among disturbances are seldom quantified, and how they will be affected by climate change is even more uncertain. In this study, we sought to better understand how interactions among disturbances shift under climate change by applying a process-based landscape disturbance and succession model (LANDIS-II) to project disturbance regimes under climate change in north-central Minnesota, USA. Specifically, we (1) contrasted mortality rates and the extent of disturbance for four individual (single) disturbance regimes (fire, insects, wind, or forest management) vs. all four disturbance regimes operating simultaneously (concurrent) under multiple climate change scenarios and (2) determined how climate change interacts with …

The urban ecosystems we inhabit provide essential ecosystem services to humans, such as air pollution removal, as well as effective means to avoid costs related to urban development, such as stormwater treatment. A better understanding of the value of ecosystem services and their spatial distribution in urban areas is vital to widespread, wholistic understanding of the relationship of environmental, economic, and social conditions. As such, it should be a component of education in grades 6-12, college, and continuing education. i-Tree Landscape is a free, online model developed by the USDA Forest Service in which users can select a geography (i.e. …
First Stewards: Ecological Outcomes Of Forest And Wildlife Stewardship By Indigenous Peoples Of Wisconsin, Usa, Donald M. Waller, Nicholas J. Reo
First Stewards: Ecological Outcomes Of Forest And Wildlife Stewardship By Indigenous Peoples Of Wisconsin, Usa, Donald M. Waller, Nicholas J. Reo

Indigenous peoples manage forestlands and wildlife differently than public and private forestland managers. To evaluate ecological outcomes from these differences, we compared the structure, composition, and diversity of Ojibwe and Menominee tribal forests to nearby nontribal forestlands in northern Wisconsin. These indigenous peoples seek to manage forests for mature conditions, accommodate wolves and other predators, and hunt deer to sustain traditional livelihood values. Their forests are often more mature with higher tree volume, higher rates of tree regeneration, more plant diversity, and fewer invasive species than nearby nontribal forestlands. In contrast, nontribal forestlands lost appreciable plant diversity in the 20th …
