Each summer the Northern Great Plains Exotic Plant Management Team visits the Niobrara NSR to spray noxious weeds and map treated acres. The NPS also works within the Middle Niobrara Weed Awareness Group (MNWAG) to encourage and assist private landowners in controlling noxious weeds. Both land (ATV and backpack) and aerial spraying have been utilized in controlling purple loosestrife, Canada thistle and leafy spurge. The NPS hopes to begin spraying with local park staff in 2008 to better control invasive species.
