“Wildfire and climate change adaptation of western US Forests"

Forest landscapes across western North America (wNA) have experienced extensive changes over the last two centuries, while climatic warming has become a rapidly expanding global reality over the last four decades. Resulting interactions between historical increases in forested area and density and recent rapid warming, increasing insect mortality, and wildfire burned areas, are now leading to substantial abrupt landscape alterations. These outcomes are forcing forest planners and managers to identify strategies that can modify future outcomes that are ecologically and/or socially undesirable. Past forest management, including widespread harvest of fire- and climate-tolerant large old trees and old forests, fire exclusion (both Indigenous and lightning ignitions), and highly effective wildfire suppression have contributed to the current state of wNA forests. These practices were successful at meeting short-term demands, but they match poorly to modern realities. I will concisely relate the findings in a recent trilogy of invited review articles. First, I will summarize a century of research reviewed in Hagmann et al. (2021) that details widespread changes in forested landscapes and wildfire regimes since the influx of European colonists. Next, I will recap research by Prichard et al. (2021) that addressed 10 common questions surrounding application and relevance of management practices historically applied by Indigenous tribes and currently applied by some managers to intentionally manage forests for climate adapted-resilient conditions. I will close by recapping recommendations for intentional adaptive management made in a third paper by Hessburg et al. (2021). To do so, I will discuss progress paralysis that can occur with strict adherence to the precautionary principle; offer insights for dealing with the problem of irreducible uncertainty; provide suggestions for reframing management and policy direction; and identify key knowledge gaps and research needs.

“Traditional ecological knowledge in the Klamath River Basin: a salmon and lamprey case study”

For tens of thousands of years, salmon, sturgeon, lamprey, and other fish have been keystone cultural species for Native American tribes of the Klamath River Basin. Such a long-term successful relationship exemplifies indigenous people’s ability to maintain a sustainable fishery. This illustrates the depth of knowledge tribes possess regarding fish and water management. As a tribal scientist, my work merges the paradigms of traditional ecological knowledge (TEK) and western ecological knowledge. Walking on both paths creates many challenges as the two concepts have significantly contrasting worldviews. The TEK worldview embodies that living resources and culture are singular, with nature completely intertwined with humanity. Language, ceremony, cultural construct, and food sources evolved synchronously. From a TEK conservation perspective, species loss not only represents a loss of biodiversity but a loss of cultural heritage as well. Therefore, protecting the remaining biodiversity on aboriginal lands is not optional because indigenous people and animal species share a common vulnerability – a struggle for survival. At the core of tribal sovereignty is food sovereignty. Traditional foods are a foundational part of tribal cultures which feed much more than physical bodies. Traditional foods feed Spirits because these foods represent a living link with the land. We truly are what we eat, we eat the earth.

Getting to the heart of science communication”

From droughts to fires to climate change, many issues that scientists and science communicators work on are highly emotional, often contentious, and sometimes traumatizing, with high stakes for practitioners -- who are often in precarious positions -- and communities alike. Relating, listening, working with conflict, and understanding trauma, all with an eye toward justice, are key tools in the 21st century science communication toolkit. Using examples from her own and other’s work, Dr. Kearns will also share tips on navigating sometimes difficult discussions.
