This data release consists of the following components: Sex ratio data from cottonwood trees at random points on the floodplain in the North and South units of Theodore Roosevelt National Park, ND. These data were used to investigate the effects of age, height above, and distance from the channel on mortality of male and female trees of plains cottonwood (Populus deltoides subsp. monilifera) as described in the Friedman and Griffin (2017) report. Tree core and tree ring data from the North and South Units of Theodore Roosevelt National Park, North Dakota. South Unit data was collected in April 2012, North Unit data was collected in the summer and fall of 2010. The trees are located on the floodplain of the Little...
In 1990 the US Geological Survey Fort Collins Science Center and National Park Service Water Resources Division established 133 permanent 1meter (m) X 2 m plots along the Gunnison River near Warner Point in Black Canyon of the Gunnison National Park. A one-dimensional hydraulic model was calibrated to determine the inundation necessary to inundate each plot, and this can be combined with daily flow data to determine the inundation duration or percentage of time a plot is under water. Occurrence of all plant species in these plots was determined in late July of 1990, 1994, 2001, 2006 and 2013. This data set includes 3 csv files of plot data. One file gives characteristics of plots, including plot name, inundating...

This dataset contains tree-ring data from plains cottonwood (Populus deltoides subsp. monilifera), narrowleaf cottonwood (Populus angustifolia) and their hybrids collected from floodplains within the Wind River Indian Reservation, Wyoming in 2017 and 2018. Samples were collected from trees at three sites: the Wind River upstream of Boysen Reservoir (latitude 43.127 N, longitude -108.232 W), the Wind River downstream of Diversion Dam (latitude 43.219 N, longitude -108.940 W) and Owl Creek near Arapaho Ranch, latitude 43.725 N, longitude -108.570 W. There are 3 files. Cottonwood_Wind_Tree_Data.csv contains descriptive information about each of the sampled trees, Cottonwood_Wind_Ring_Widths contains the tree-ring widths...
