Geographic location of data collection (where was data collected?): The associated data file was collected within the Kains Switch South (KSS) forest management site in collaboration with the University of Minnesota, U.S. Geological Survey, and U. S. Army Corps of Engineers to quantify survival and growth of planted floodplain species. 6. Information about funding sources that supported the collection of the data: Funding for this project was provided by Northern Forest CESU agreement between the U.S. Army Corps of Engineers and University of Minnesota (W912HZ-18-2-0004), Minnesota Agriculture Experiment Station (MIN-42-108), and the U.S. Army Corps of Engineers Upper Mississippi River Restoration Program 7. Overview of the data (abstract): The study site is within the Kains Switch South (KSS) forest management site, a U. S. Army Corps of Engineers’ forest management site located on the western edge of the Upper Mississippi River floodplain between river miles 668.2 and 670.3 and within navigation Pool 9. The site is approximately 5 miles (8 km) south of New Albin, IA, and the Minnesota/Iowa border in Allamakee County, IA. Nine plots were established at KSS spanning an elevation gradient, with three plots per elevation quantile (high, 626.5 to 628.5 ft [190.9 to 191.6 m]; intermediate, 624.5 to 626.5 ft [190.3 – 190.9 m]; and low, 622.5 to 624.5 ft [189.7 to 190.3 m]). A total of 64 seedlings were planted in each plot in an 8 x 8 grid with 10 ft x 10 ft cell sizes (3 by 3 m), with 16 individuals representing each of the following species: swamp white oak (Quercus bicolor Willd.), silver maple (Acer saccharinum L.), sycamore (Platanus occidentalis L.), and hackberry (Celtis occidentalis L.). Orientation of the grid was north/south. Species’ cell assignments were random and placement within the 10 ft x 10 ft (3 by 3 m) cell was also random. Initial measurements of species, basal diameter, height, and initial notes regarding seedling vigor and health and evidence of herbivory occurred in June 2020. End-of-growing-season measurements (same as initial variables) occurred in September 2020 and October 2021and included the same measurements as the initial measurements. An additional survival assessment occurred in June 2021. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

Description of methods used for collection/generation of data: The study site is within the Kains Switch South (KSS) forest management site, a USACE forest management site located on the western edge of the Mississippi River floodplain between river miles 668.2 and 670.3 within navigation Pool 9. The site is approximately 5 miles (8 km) south of New Albin, IA, and the Minnesota/Iowa border in Allamakee County, IA. The KSS encompasses 660.5 ac (267.3 ha) of USACE-owned lands and is within one of the largest contiguous tracts of floodplain forest of the USACE Ð St. Paul District. We utilized elevation gradients as a surrogate for a suite of environmental conditions believed to influence forest composition and structure (e.g., soil moisture, nutrient availability, texture, and inundation regime). We divided the distribution of elevations at KSS into three quantiles and mapped these quantiles to identify high (highest elevation quantile; (626.5 to 628.5 ft [190.9 to 191.6 m]), intermediate (moderate elevation quantile; (624.5 to 626.5 ft [190.3 Ð 190.9 m]), and low (lowest elevation quantile; 622.5 to 624.5 ft [189.7 to 190.3 m]) elevation zones. Within each of the three zones, locations with intermediate canopy coverage (~60 percent closed) were identified using first-return light detection and ranging (lidar) data (Sattler and Hoy 2020), followed by on-site assessments to confirm canopy densities. The final plots were randomly selected from the set of viable locations identified during the on-site assessments; plot size was 0.143 ac (578 m2). Three plots that had similar overstory canopy coverage (~60 percent overstory canopy) were selected within each zone, resulting in a total of nine plots. Competing vegetation was present on most plots but was variable in composition and density; one of the highest elevation sites had high densities of reed canary grass, but wood nettle (Laportea canadensis L.), giant ragweed (Ambrosia trifida L.), and rice cutgrass (Leersia oryzoides L.) were more prevalent competitors across most sites. Within each of the 9 plots, a total of 64 seedlings were planted in an 8 x 8 grid with 10 ft x 10 ft cell sizes (3 by 3 m), with 16 individuals representing each of the following species: swamp white oak (Quercus bicolor Willd.), silver maple, sycamore (Platanus occidentalis L.), and hackberry (Celtis occidentalis L.). Orientation of the grid was north/south. SpeciesÕ cell assignments were randomly assigned, and placement within the 10 ft x 10 ft (3 by 3 m) cell was also random. Seedlings were planted over two days (May 21 and 22) in the spring of 2020 by staff from the USACE and USFWS; staff received training on tree planting. Initial measurements of the seedlings were conducted one week later by staff at the University of Minnesota; measurements included species, basal diameter, height, and initial notes regarding seedling vigor and health, and evidence of herbivory. Each individual seedling was mapped within the plot for detailed record for future measurements. During the 2020 and 2021 field seasons, field crews applied herbivory protection (PlantSkydd¨) once annually in June. Later in the growing season (late June or early July), competing vegetation was controlled manually with a brush saw to maintain a free-to-grow condition. End-of-growing-season measurements (same as initial variables) occurred in September and October 2020 and 2021, respectively, and include the same measurements as the initial measurements. An additional survival assessment occurred in June 2021. Methods from: Windmuller-Campione, M., Van Appledorn, M., Meier, A., Reuling, L. in press.
