Abstract

The Ministry for Primary Industries (MPI) has targeted Salvinia molesta (salvinia) Eichhornia crassipes (water hyacinth) Sorghum halepense (Johnson grass) and Moraea flaccida (cape tulip) for eradication under the national interest pest response (NIPR) programme These weeds are both notifiable and unwanted organisms under the Biosecurity Act 1993 The NIPR eradication programme consists of educational campaigns; enforcement of the Biosecurity Act which prohibits propagation planting sowing sale and distribution of the weeds; removal and destruction of the weeds from known infested sites; and monitoring those sites for regrowth Assessment over the past two decades shows that Johnson grass and cape tulip have responded well to management As at 2013 the number of active Johnson grass sites has reduced by 100 and cape tulip by 74 The number of active sites for water hyacinth and salvinia however keeps rising and falling thus prolonging eradication
