Abstract
Banff National Park (BNP) is Canada’s oldest national park and a very popular one, with both year-round residents and millions of annual visitors. In turn, this means there are several busy road and rail transportation routes throughout the park. These factors can have a number of negative effects on local wildlife. The wildlife crossing structures of the Trans-Canada Highway in BNP have become a key conservation tool to conserve biodiversity in the park and beyond. As the first large-scale operation of highway mitigation of its kind in North America, it is a perfect case for understanding the conservation value of highway overpasses and underpasses for a variety of wildlife species including both large and small mammals. It was determined from the research that there is a vast majority of information available for large mammals compared to small mammals. Small mammals used the crossing structures to avoid predators, while large mammals used the crossing structures to avoid humans. The design of the structure was extremely influential on its effectiveness with black bears and cougars preferring narrow bridges with cover, elk preferring wide, open bridges, and smaller mammals, such as weasels, snowshoe hares, and some mice preferring culverts with vegetation cover.

Abstract
‘Ōhi‘a lehua is a species of tree endemic to the islands of Hawai‘i. Its existence is vital to the survival of many pollinator insects and endangered bird species and to the integrity of multiple islands’ watersheds. Rapid ‘Ōhi‘a Death (ROD) is an emerging fungal disease that poses a significant health risk for these trees and is spread by human traffic, ambrosia beetles, and wind dispersal. Loss of ‘ōhi’a forests will negatively affect Hawai‘i’s economy and ecology and will have detrimental impacts on Hawaiian culture, particularly because of the role of lehua flowers in hula. While transmission of ROD Death is not yet fully understood, human activity is currently considered the main proponent of its spread. Hawai‘i’s economy is largely built on the tourism industry; however, tourists are often unaware of the disease and the practices implemented to contain the current outbreak while visiting the Hawaiian Islands. ROD is a conservation issue that connects humans with the environment and must be addressed using a one-health perspective. This article aims to elucidate the anthropogenic factors contributing to the depletion of ‘ōhi‘a lehua through the spread of ROD and to propose prevention measures that can be adopted by citizens and visitors. At the end of this case study, readers will understand the cultural, ecological, and economic significance of ‘ōhi’a lehua. Readers will also be able to identify important stakeholders and examine the complexity of behavior change in conservation issues.
