    其他: Its early emergence and great height combine to shade out other vegetation and prohibit regeneration of other species (Sukopp and Sukopp 1988, in Seiger, 1991). Thus, it reduces species diversity and damages wildlife habitat (Palmer 1990, Scott and Mars 1984, Wiegman pers. comm., in Seiger, 1991).
    改變演化模式: It is a dominant pioneer in the primary succession of volcanic slopes and is frequently a coloniser in secondary succession (Hirose, 1984, in Seiger, 1991).
    改變營養機制: Seiger (1991) states that it contributes to the development of the ecosystem, in part, by acting as a nutrient reservoir.
    競爭: Remaley (1997) states that it spreads quickly to form dense thickets that exclude native vegetation and greatly alter natural ecosystems.
