Hot child in the city: Drivers of urban buffelgrass presence in Tucson, Arizona

Invasive species distributions and ecological impacts in natural ecosystems have been broadly studied, but invasive species urban distributions and impacts on human populations warrant further investigation. Urban areas are highly disturbed environments at high risk of invasion by non‐native species, and urban infrastructure can influence the dispersal and abundance of invasive species. Furthermore, in areas with concentrated human populations, invasive species may pose a risk to human as well as native biota. Here, we examine (1) how high‐traffic roadways and the presence of suitable habitat influence buffelgrass abundance in residential areas and (2) whether buffelgrass differentially invades residential areas across socioeconomic levels and racial diversity indices in Tucson, Arizona. We found that, within residential areas, the presence of vacant lots was positively associated with buffelgrass abundance; however, there was no relationship between other suitable habitat types and buffelgrass abundance. We found no relationship between road type and buffelgrass abundance in residential areas. We found that lower‐income communities were more likely to be invaded by buffelgrass, but there was no relationship between racial diversity index and buffelgrass abundance. Understanding drivers of invasive species presence and abundance in urban areas is necessary to inform urban management strategies to prevent spread to surrounding wildlands.
