Abstract Research partnerships between Tribal Nations and rural colleges and universities can support rural development and strengthen Tribal Nation building through reclamation of economic, political, cultural, and social affairs. However, Tribal Nation–University relationships have received little attention in rural sociology. While scholars identify best practices for research engagement in light of colonial harms, the ideal visions that Tribally and university‐affiliated people have for research partnerships and the barriers to achieving those ideals are poorly understood. Without identifying these visions and barriers, we risk making wrong assumptions about each party's needs and cannot implement appropriate policies. Semi‐structured interviews with Tribally‐affiliated (n = 20) and university‐affiliated (n = 20) people in rural southeastern Idaho suggest, contrary to literature on best practices for collaborative research, that participants in both groups viewed what we term “Tribally‐responsive research engagement” as ideal, though few projects met this goal. Tribally‐responsive research directly addressed Tribal priorities but did not necessarily involve close collaboration. The University's failure to acknowledge past or colonial harms, university‐affiliated researchers' historicization of those harms, and negative Native student experiences reinforced distrust, limiting desired research engagement. In sum, Tribally‐responsive research engagement could strengthen Native Nation building, but requires universities to acknowledge harms, create more welcoming campus environments, and prioritize Tribal benefits in research. 

Abstract Increasing frequency of droughts and wildfire are sparking concerns that these compounded disturbance events are pushing forested ecosystems beyond recovery. An improved understanding of how compounded events affect tree physiology and mortality is needed given the reliance of fire management planning on accurate estimates of postfire tree mortality. In this study, we use a toxicological dose-response approach to quantify the impact of variable-intensity drought and fire on the physiology and mortality of Pinus monticola and Pseudotsuga menziesii saplings. We show that the dose-response relationship between fire intensity and mortality shifts toward increased vulnerability under drought, indicating higher mortality with increasing drought at any fire intensity. The trajectory we observed in postfire chlorophyll fluorescence, an indicator of photosynthetic efficiency and stress, was an effective early warning sign of impending tree death. Postfire mortality modeling shows that accurate mortality classification can be achieved using prefire physiology and morphology metrics combined with fire intensity. Variable importance measures indicate that physiological condition and fire intensity have greater influence on the classification accuracy than morphological metrics. The wide range in drought and fire responses observed between this study and others highlights the need for more research on compound disturbance effects. Study Implications: An improved understanding of how drought and fire affect tree physiology and mortality is needed by natural resource managers looking to predict postfire tree mortality. This study advances our compound disturbance understanding by subjecting conifer saplings to variable drought and fire intensities and quantifying and modeling moderate-term recovery and mortality. The results show reduced physiological recovery and amplified mortality in saplings exposed to greater drought and fire intensity. Overall, this study highlights the importance of physiological condition when modeling tree mortality and could potentially be used to inform current postfire tree mortality models. 

Background The increased interest in why and how trees die from fire has led to several syntheses of the potential mechanisms of fire-induced tree mortality. However, these generally neglect to consider experimental methods used to simulate fire behaviour conditions. Aims To describe, evaluate the appropriateness of and provide a historical timeline of the different approaches that have been used to simulate fire behaviour in fire-induced tree mortality studies. Methods We conducted a historical review of the different actual and fire proxy methods that have been used to further our understanding of fire-induced tree mortality. Key results Most studies that assess the mechanisms of fire-induced tree mortality in laboratory settings make use of fire proxies instead of real fires and use cut branches instead of live plants. Implications Further research should assess mechanisms of fire-induced tree mortality using live plants in paired combustion laboratory and landscape fire experiments. 

Understanding the indirect and interactive effects of environmental stressors is critical to planning conservation interventions, but such effects are poorly understood. For example, invasive species may modify fire effects by altering fire intensity or frequency, increasing or decreasing their abundance in response to fire, and/or changing the trajectory of post‐fire recovery. Without a clear understanding of the direct, indirect, and interactive effects of prescribed fire and invasive species on native plants, managers cannot design effective conservation measures and risk exacerbating invasion through fire or wasting resources on approaches that do not yield desired results. In this study, researchers worked directly with the manager of a wet meadow in southern Idaho to explore how prescribed fire would directly and indirectly impact an iconic native herb (Camassia quamash) in areas invaded by a perennial pasture grass (Alopecurus arundinaceus). We found that spring prescribed fire increased the abundance of invasiveA. arundinaceus, which indirectly strengthened its suppression ofC. quamashgrowth and reproduction. In contrast, fire reversed the negative influence ofA. arundinaceusonC. quamashsurvival. Survival rates ofC. quamashwere higher after fire in areas with greater invasive grass abundance. This study points to the importance of understanding the indirect and interactive effects of prescribed fire and invasives on native plants across their life cycle for restoration projects and suggests fire, at least in spring, is not an appropriate management strategy for reducingA. arundinaceusinvasion at this site. 

Background The decision making process undertaken during wildfire responses is complex and prone to uncertainty. In the US, decisions federal land managers make are influenced by numerous and often competing factors. Aims To assess and validate the presence of decision factors relevant to the wildfire decision making context that were previously known and to identify those that have emerged since the US federal wildfire policy was updated in 2009. Methods Interviews were conducted across the US while wildfires were actively burning to elucidate time-of-fire decision factors. Data were coded and thematically analysed. Key results Most previously known decision factors as well as numerous emergent factors were identified. Conclusions To contextualise decision factors within the decision making process, we offer a Wildfire Decision Framework that has value for policy makers seeking to improve decision making, managers improving their process and wildfire social science researchers. Implications Managers may gain a better understanding of their decision environment and use our framework as a tool to validate their deliberations. Researchers may use these data to help explain the various pressures and influences modern land and wildfire managers experience. Policy makers and agencies may take institutional steps to align the actions of their staff with desired wildfire outcomes. 

Water supply is a critical component of tree physiological health, influencing a tree’s photosynthetic activity and resilience to disturbances. The climatic regions of the western United States are particularly at risk from increasing drought, fire, and pest interactions. Existing methods for quantifying drought stress and a tree’s relative resilience against disturbances mostly use moderate-scale (20–30 m) multispectral satellite sensor data. However, tree water status (i.e., water stress) quantification using sensors like Landsat and Sentinel are error-prone given that the spectral reflectance of pixels are a mixture of the dominant tree canopy, surface vegetation, and soil. Uncrewed aerial systems (UAS) equipped with multispectral sensors could potentially provide individual tree water status. In this study, we assess whether the simulated band equivalent reflectance (BER) of a common UAS optical multispectral sensor can accurately quantify the foliar moisture content and water stress status of individual trees. To achieve this, water was withheld from groups of Douglas-fir and western white pine saplings. Then, measurements of each sapling’s foliar moisture content (FMC) and spectral reflectance were converted to BER of a consumer-grade multispectral camera commonly used on UAS. These bands were used in two classification models and three regression models to develop a best-performing FMC model for predicting either the water status (i.e., drought-stressed or healthy) or the foliar moisture content of each sapling, respectively. Our top-performing models were a logistic regression classification and a multiple linear regression which achieved a classification accuracy of 96.55% and an r2 of 82.62, respectively. These FMC models could provide an important tool for investigating tree crown level water stress, as well as drought interactions with other disturbances, and provide land managers with a vital indicator of tree resilience.
