狀態: 外來 入侵: 出現紀錄: ????? 來源: Mullerova et al, 2005; Perglova et al, 2006; Hejda et al, 2009; Westbrooks, 1991; EPPO, 2006 此地點的物種說明: Heralceum mantegazzianum was introduced to the Czech Rebublic as a garden ornamental in 1862 (Mullerova et al, 2005). It was introduced in the park of a chateau at Lázně Kynžvart and has heavily invaded Slavkovský les (Perglova et al, 2006).. It is recorded from over 600 localities in the Czech Republic and continues to spread (Nehrbass et al, 2006). It popularity as an ornamental is the principal factor contributing to its spread (Pysek, 1991). 影響: 生態系統變化: Heracleum mantegazzianum increases the erosion of river banks after plants dieback in the winter (Pysek, 1991). 降低本地生物多樣性: Heracleum mantegazzianum forms monospecific stands which reduce species diversity in the Czech Republic (Hejda et al, 2009; Nehrbass et al, 2006; Pysek, 1991). 最後修改 : 23/02/2011 3:18:59 p.m.
