Vegetation and geomorphic surfaces in the Elwha River delta, Washington, after dam removal, derived from 2016 and 2018 aerial imagery and 2007, 2014, and 2018 field surveys

Removal of two large dams from the Elwha River, Washington USA, in 2011-2014 released ~20.5 metric tons (Mt) of impounded sediment, ~5.4 Mt of which was deposited in the river delta and estuary. This dataset presents measurements of geomorphic surfaces, vegetation colonization, and plant community development in the Elwha River delta and estuary after dam removal. Geomorphic surfaces and vegetation colonization were estimated from aerial imagery of the delta and estuary in 2016 and 2018. Plant community development was quantified from field plot surveys of pioneer plant communities on new surfaces in 2014 and 2018 and of established delta and estuarine plant communities on older surfaces in 2007, 2014, and 2018....

Riparian vegetation, topography, and sediment quality along the Lower Virgin River 2010-2021 (ver. 2.0, January 2025)

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...
