| Abstract | Reducing jeopardy to pallid sturgeon in the Missouri River is a fundamental objective of the Missouri River Recovery Program (MRRP). Uncertainties related to potential management actions for how to accomplish this are expressed as “Big Questions”. We conducted a survey to inform MRRP interests of how Upper and Lower Missouri River pallid sturgeon professionals prioritized these Big Questions. Email lists from the Upper and Middle Basin Pallid Sturgeon Work Groups constituted pallid “experts’. Each group was surveyed independently and each was asked to rank the six Upper or Lower basin Big Question across seven levels ranging from Most Important to Least Important and also requested to write-in their own Big Question if an important issue was considered absent. Drift Dynamics (34%) and Spawning Cues (31%) were ranked as most important by Upper Basin respondents. However, 44% identified an additional Big Question as the most important issue. Sediment Augmentation (31%) and Population Augmentation (24%) were ranked as Least Important. Lower Basin respondents identified Food and Forage (39%) as the Most Important Big Question, although most respondents (44%) again ranked their additional Big Question as Most Important. Decline in pallid sturgeon condition was ranked highest by 5 of the 8 respondents as their Most Important Additional Big Question. Temperature control (25%) and Population Augmentation (14%) were ranked as Least Important by Lower Basin respondents. Results can help decision makers prioritize management actions to reduce pallid sturgeon jeopardy and identify additional issues considered significant by sturgeon professionals. Title: Research Framework to Support Missouri River Adaptive Management: Comprehensive Sturgeon Research Project 2018–2020 Author(s): Aaron J. DeLonay, Patrick J. Braaten, Kimberly A. Chojnacki, Caroline M. Elliott, Susannah O. Erwin, Edward J. Heist, Mather L. Rugg, and Casey A. Hickox Mailing Address of Presenter: Aaron J. DeLonay U.S. Geological Survey Columbia Environmental Research Center 4200 New Haven Road Columbia, MO 65202 Email Address of Presenter: adelonay@usgs.gov Abstract: The Comprehensive Sturgeon Research Project (CSRP) is an ongoing multiyear, multiagency collaborative research framework developed to support information needs for pallid sturgeon recovery and Missouri River management actions, including channel re-engineering, flow modification, and pallid sturgeon population augmentation. The CSRP science is developed building on previous years’ work, results of the Missouri River Pallid Sturgeon Effects Analysis (EA), and ongoing prioritization discussions emanating from the Missouri River Science and Adaptive Management Plan (MRSAMP). The project consists of several interdependent and complementary tasks that engage multiple disciplines. Planned research in 2018–2020 emphasizes information related to reproductive migrations, spawning, and embryo development, hatch, dispersal and retention. Studies include refined understanding of reproductive cues, characteristics of functional spawning habitats, spawning patch dynamics, and the interrelationships between physical processes and survival during critical early life stages. Physical and biological understanding will be used to refine existing models and to develop new models of spawning, dispersal of free embryos, and interception of young-of-year sturgeon into supportive habitats. Technologies will be developed to improve the use of telemetry and remote monitoring of sturgeon responses at the patch, bend and segment scale. Additional studies will assess fundamental questions about pallid sturgeon genetic structure, variation within subpopulations, effective population size, and hybridization frequency and extent. Information provided by CSRP will be collaboratively synthesized and assimilated into the science and adaptive management process.

Dixon, and James E. Vogelmann Mailing Address of Presenter: Nadeesha Dilrukshi Illeperum Archchige Done University of South Dakota 414 East Clark Street Vermillion, SD 57069 Email Address of Presenter: nadeesha.illeperumaa@coyotes.usd.edu Abstract: Dam construction along the Missouri River has reduced flooding, altering geomorphic processes and flood-plain vegetation. A major threat to riparian habitats is the spread of invasive species. Over the last several decades, eastern redcedar (Juniperus virginiana L.), a native upland species, has invaded the understory of cottonwood forests along the Missouri River. A major flood in 2011, however, caused significant die-off of redcedar at some locations. Our goal was to map the historical spread of redcedar, assess the impacts of the 2011 flood on redcedar abundance, and determine where significant post-flood recovery of redcedar has occurred within the Missouri National Recreational River. To accomplish this, we used ArcGIS and remote sensing techniques, including the use of spectral vegetation indices (Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI)), to map redcedar abundance in the study area from the 1980s to present. We determined the relationship between NDVI values with redcedar canopy cover using 2017 satellite images and field data. Results indicated a linear relationship between redcedar cover and NDVI values (P-value: 0.0001, R-square: 0.88). Historical time series maps which were generated from NDVI images showed that redcedar cover was detectable on less than 10% of the woodland and grassland area in 1982, expanded to nearly 55% by 2010, and then declined by nearly 10% after the 2011 flood. Our results show the utility of remote sensing methods for tracking cedar invasion and suggest the importance of historical floods for constraining invasion and maintaining native forest communities.
