    Impacts:
    Agricultural: Mehrhoff et al (2001) states that, "Buckthorn control is also of interest to small grain producers; the shrub is an alternate host of the crown rust of oats, which affects oat yield and quality."
    Modification of fire regime: Mehrhoff et al (2001) states that, "In fire-adapted ecosystems such as savannas and prairies, the lack of vegetation under buckthorn prohibits fires."
    Reduction in native biodiversity: Mehrhoff et al (2001) states that, "R. cathartica tends to form dense, even-aged thickets, crowding and shading out native shrubs and herbs, often completely obliterating them."
