Hello just wondering if this is senecio madagascariensis which I understand is "a highly invasive and toxic pest plant which is declared a Weed of National Significance. The species is a prohibited and notifiable pest plant in the ACT." or if it's Senecio pinnatifolius . In other words, should we pull out the 4 small seedlings that appeared 1 year after cultural burn or not! Thank you for your help with this.
