I examined the colonization patterns of plants in the drawdown zone of Lake Mead. There was an increase in the mean number of species over time as well as differences in the colonization patterns of two non-native plant species, Brassica tournefortii and Tamarix ramosissima. I also examined the impact of germination order on competition between B. tournefortii and four native species under controlled environmental conditions and found effects of germination order on both aboveground and belowground biomass for all species in the study. These results can aid management of the Lake Mead drawdown zone by providing an overview of how the community develops and where non-native species are likely to invade. Also, this study indicates that competitive relationships between the non-native B. tournefortii and four common native species should be considered in any efforts to control B. tournefortii.
