Russian-thistle field and seed bank data at Petrified Forest National Park, Arizona, 2015-2016

April 9, 2019

These data were compiled as part of a field and growth chamber study of the establishment of Salsola tragus (Russian thistle), an invasive non-native annual plant in North America. Field work was conducted at Petrified Forest National Park, Arizona in 2015 and 2016 and the growth chamber study was conducted in 2016. The data represent field measurements of Salsola germination and growth (cover) and sediment movement at two field sites, one a stabilized sand sheet (SS) and the other on the ridge of a sand dune (SD). The data also represent a growth chamber assessment of the soil and litter seed bank from representative samples take at the two field sites.
