Note: This data release has been preceded by version 1.0, available here: https://doi.org/10.5066/P97KZJGP.
The data release presents observations of riparian vegetation, topography, and sediment quality in five river reaches of the Lower Virgin River extending downstream 62 river kilometers (rkm), from near the town of Littlefield (Arizona) to approximately 15 rkm upstream from the confluence with the Muddy River (Nevada). Methods included field observations and analysis of the plant community before substantial biocontrol-induced dieback of invasive Tamarix spp. shrubs (surveys in 2010 and 2012) and after (surveys in 2015, 2017, and 2021). The first survey was conducted before a 40-year return period flood (December 2010, at the gaging station “Virgin River near Littlefield” (USGS gage #09415000)). The data release includes four .csv files related to field observations: UTM coordinates of field transect and vegetation plot locations; vegetation and topography; species codes; and sediment quality.
